+
+## Introduction
+
+GLFW is an Open Source, multi-platform library for OpenGL, OpenGL ES and Vulkan
+application development.  It provides a simple, platform-independent API for
+creating windows, contexts and surfaces, reading input, handling events, etc.
+
+GLFW natively supports Windows, macOS and Linux and other Unix-like systems.  On
+Linux both X11 and Wayland are supported.
+
+GLFW is licensed under the [zlib/libpng
+license](http://www.glfw.org/license.html).
+
+You can [download](http://www.glfw.org/download.html) the latest stable release
+as source or Windows binaries, or fetch the `latest` branch from GitHub.  Each
+release starting with 3.0 also has a corresponding [annotated
+tag](https://github.com/glfw/glfw/releases) with source and binary archives.
+
+The [documentation](http://www.glfw.org/docs/latest/) is available online and is
+included in all source and binary archives.  See the [release
+notes](https://www.glfw.org/docs/latest/news.html) for new features, caveats and
+deprecations in the latest release.  For more details see the [version
+history](http://www.glfw.org/changelog.html).
+
+The `master` branch is the stable integration branch and _should_ always compile
+and run on all supported platforms, although details of newly added features may
+change until they have been included in a release.  New features and many bug
+fixes live in [other branches](https://github.com/glfw/glfw/branches/all) until
+they are stable enough to merge.
+
+If you are new to GLFW, you may find the
+[tutorial](http://www.glfw.org/docs/latest/quick.html) for GLFW 3 useful.  If
+you have used GLFW 2 in the past, there is a [transition
+guide](http://www.glfw.org/docs/latest/moving.html) for moving to the GLFW
+3 API.
+
+
+## Compiling GLFW
+
+GLFW itself requires only the headers and libraries for your OS and window
+system.  It does not need the headers for any context creation API (WGL, GLX,
+EGL, NSGL, OSMesa) or rendering API (OpenGL, OpenGL ES, Vulkan) to enable
+support for them.
+
+GLFW supports compilation on Windows with Visual C++ 2010 and later, MinGW and
+MinGW-w64, on macOS with Clang and on Linux and other Unix-like systems with GCC
+and Clang.  It will likely compile in other environments as well, but this is
+not regularly tested.
+
+There are [pre-compiled Windows binaries](http://www.glfw.org/download.html)
+available for all supported compilers.
+
+See the [compilation guide](http://www.glfw.org/docs/latest/compile.html) for
+more information about how to compile GLFW yourself.
+
+
+## Using GLFW
+
+See the [documentation](http://www.glfw.org/docs/latest/) for tutorials, guides
+and the API reference.
+
+
+## Contributing to GLFW
+
+See the [contribution
+guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for
+more information.
+
+
+## System requirements
+
+GLFW supports Windows XP and later and macOS 10.8 and later.  Linux and other
+Unix-like systems running the X Window System are supported even without
+a desktop environment or modern extensions, although some features require
+a running window or clipboard manager.  The OSMesa backend requires Mesa 6.3.
+
+See the [compatibility guide](http://www.glfw.org/docs/latest/compat.html)
+in the documentation for more information.
+
+
+## Dependencies
+
+GLFW itself depends only on the headers and libraries for your window system.
+
+The (experimental) Wayland backend also depends on the `extra-cmake-modules`
+package, which is used to generate Wayland protocol headers.
+
+The examples and test programs depend on a number of tiny libraries.  These are
+located in the `deps/` directory.
+
+ - [getopt\_port](https://github.com/kimgr/getopt_port/) for examples
+   with command-line options
+ - [TinyCThread](https://github.com/tinycthread/tinycthread) for threaded
+   examples
+ - [glad2](https://github.com/Dav1dde/glad) for loading OpenGL and Vulkan
+   functions
+ - [linmath.h](https://github.com/datenwolf/linmath.h) for linear algebra in
+   examples
+ - [Nuklear](https://github.com/vurtun/nuklear) for test and example UI
+ - [stb\_image\_write](https://github.com/nothings/stb) for writing images to disk
+
+The documentation is generated with [Doxygen](http://doxygen.org/) if CMake can
+find that tool.
+
+
+## Reporting bugs
+
+Bugs are reported to our [issue tracker](https://github.com/glfw/glfw/issues).
+Please check the [contribution
+guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for
+information on what to include when reporting a bug.
+
+
+## Changelog
+
+ - [Win32] Bugfix: Super key was not released after Win+V hotkey (#1622)
+ - [Win32] Bugfix: `glfwGetKeyName` could access out of bounds and return an
+   invalid pointer
+ - [Win32] Bugfix: Some synthetic key events were reported as `GLFW_KEY_UNKNOWN`
+   (#1623)
+ - [Cocoa] Added support for `VK_EXT_metal_surface` (#1619)
+ - [Cocoa] Added locating the Vulkan loader at runtime in an application bundle
+ - [X11] Bugfix: `glfwFocusWindow` could terminate on older WMs or without a WM
+ - [X11] Bugfix: Creating an undecorated window could fail with BadMatch (#1620)
+ - [X11] Bugfix: Querying a disconnected monitor could segfault (#1602)

+ * The master copy of khrplatform.h is maintained in the Khronos EGL
+ * Registry repository at https://github.com/KhronosGroup/EGL-Registry
+ * The last semantic modification to khrplatform.h was at commit ID:
+ *      67a3e0864c2d75ea5287b9f3d2eb74a745936692
+ *
+ * Adopters may modify this file to suit their platform. Adopters are
+ * encouraged to submit platform specific modifications to the Khronos
+ * group so that they can be included in future versions of this file.
+ * Please submit changes by filing pull requests or issues on
+ * the EGL Registry repository linked above.
+ *
+ *
+ * See the Implementer's Guidelines for information about where this file
+ * should be located on your system and for more details of its use:
+ *    http://www.khronos.org/registry/implementers_guide.pdf
+ *
+ * This file should be included as
+ *        #include <KHR/khrplatform.h>
+ * by Khronos client API header files that use its types and defines.
+ *
+ * The types in khrplatform.h should only be used to define API-specific types.
+ *
+ * Types defined in khrplatform.h:
+ *    khronos_int8_t              signed   8  bit
+ *    khronos_uint8_t             unsigned 8  bit
+ *    khronos_int16_t             signed   16 bit
+ *    khronos_uint16_t            unsigned 16 bit
+ *    khronos_int32_t             signed   32 bit
+ *    khronos_uint32_t            unsigned 32 bit
+ *    khronos_int64_t             signed   64 bit
+ *    khronos_uint64_t            unsigned 64 bit
+ *    khronos_intptr_t            signed   same number of bits as a pointer
+ *    khronos_uintptr_t           unsigned same number of bits as a pointer
+ *    khronos_ssize_t             signed   size
+ *    khronos_usize_t             unsigned size
+ *    khronos_float_t             signed   32 bit floating point
+ *    khronos_time_ns_t           unsigned 64 bit time in nanoseconds
+ *    khronos_utime_nanoseconds_t unsigned time interval or absolute time in
+ *                                         nanoseconds
+ *    khronos_stime_nanoseconds_t signed time interval in nanoseconds
+ *    khronos_boolean_enum_t      enumerated boolean type. This should
+ *      only be used as a base type when a client API's boolean type is
+ *      an enum. Client APIs which use an integer or other type for
+ *      booleans cannot use this as the base type for their boolean.
+ *
+ * Tokens defined in khrplatform.h:
+ *
+ *    KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
+ *
+ *    KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
+ *    KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.

+ * Calling convention macros defined in this file:
+ *    KHRONOS_APICALL
+ *    KHRONOS_APIENTRY

+/// ## About
+/// This is a minimal state immediate mode graphical user interface toolkit
+/// written in ANSI C and licensed under public domain. It was designed as a simple
+/// embeddable user interface for application and does not have any dependencies,
+/// a default renderbackend or OS window and input handling but instead provides a very modular
+/// library approach by using simple input state for input and draw
+/// commands describing primitive shapes as output. So instead of providing a
+/// layered library that tries to abstract over a number of platform and
+/// render backends it only focuses on the actual UI.
+///
+/// ## Highlights
+/// - Graphical user interface toolkit
+/// - Single header library
+/// - Written in C89 (a.k.a. ANSI C or ISO C90)
+/// - Small codebase (~18kLOC)
+/// - Focus on portability, efficiency and simplicity
+/// - No dependencies (not even the standard library if not wanted)
+/// - Fully skinnable and customizable
+/// - Low memory footprint with total memory control if needed or wanted
+/// - UTF-8 support
+/// - No global or hidden state
+/// - Customizable library modules (you can compile and use only what you need)
+/// - Optional font baker and vertex buffer output
+///
+/// ## Features
+/// - Absolutely no platform dependent code
+/// - Memory management control ranging from/to
+///     - Ease of use by allocating everything from standard library
+///     - Control every byte of memory inside the library
+/// - Font handling control ranging from/to
+///     - Use your own font implementation for everything
+///     - Use this libraries internal font baking and handling API
+/// - Drawing output control ranging from/to
+///     - Simple shapes for more high level APIs which already have drawing capabilities
+///     - Hardware accessible anti-aliased vertex buffer output
+/// - Customizable colors and properties ranging from/to
+///     - Simple changes to color by filling a simple color table
+///     - Complete control with ability to use skinning to decorate widgets
+/// - Bendable UI library with widget ranging from/to
+///     - Basic widgets like buttons, checkboxes, slider, ...
+///     - Advanced widget like abstract comboboxes, contextual menus,...
+/// - Compile time configuration to only compile what you need
+///     - Subset which can be used if you do not want to link or use the standard library
+/// - Can be easily modified to only update on user input instead of frame updates
+///
+/// ## Usage
+/// This library is self contained in one single header file and can be used either
+/// in header only mode or in implementation mode. The header only mode is used
+/// by default when included and allows including this header in other headers
+/// and does not contain the actual implementation. <br /><br />
+///
+/// The implementation mode requires to define  the preprocessor macro
+/// NK_IMPLEMENTATION in *one* .c/.cpp file before #includeing this file, e.g.:
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~C
+///     #define NK_IMPLEMENTATION
+///     #include "nuklear.h"
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// Also optionally define the symbols listed in the section "OPTIONAL DEFINES"
+/// below in header and implementation mode if you want to use additional functionality
+/// or need more control over the library.
+///
+/// !!! WARNING
+///     Every time nuklear is included define the same compiler flags. This very important not doing so could lead to compiler errors or even worse stack corruptions.
+///
+/// ### Flags
+/// Flag                            | Description
+/// --------------------------------|------------------------------------------
+/// NK_PRIVATE                      | If defined declares all functions as static, so they can only be accessed inside the file that contains the implementation
+/// NK_INCLUDE_FIXED_TYPES          | If defined it will include header `<stdint.h>` for fixed sized types otherwise nuklear tries to select the correct type. If that fails it will throw a compiler error and you have to select the correct types yourself.
+/// NK_INCLUDE_DEFAULT_ALLOCATOR    | If defined it will include header `<stdlib.h>` and provide additional functions to use this library without caring for memory allocation control and therefore ease memory management.
+/// NK_INCLUDE_STANDARD_IO          | If defined it will include header `<stdio.h>` and provide additional functions depending on file loading.
+/// NK_INCLUDE_STANDARD_VARARGS     | If defined it will include header <stdio.h> and provide additional functions depending on file loading.
+/// NK_INCLUDE_VERTEX_BUFFER_OUTPUT | Defining this adds a vertex draw command list backend to this library, which allows you to convert queue commands into vertex draw commands. This is mainly if you need a hardware accessible format for OpenGL, DirectX, Vulkan, Metal,...
+/// NK_INCLUDE_FONT_BAKING          | Defining this adds `stb_truetype` and `stb_rect_pack` implementation to this library and provides font baking and rendering. If you already have font handling or do not want to use this font handler you don't have to define it.
+/// NK_INCLUDE_DEFAULT_FONT         | Defining this adds the default font: ProggyClean.ttf into this library which can be loaded into a font atlas and allows using this library without having a truetype font
+/// NK_INCLUDE_COMMAND_USERDATA     | Defining this adds a userdata pointer into each command. Can be useful for example if you want to provide custom shaders depending on the used widget. Can be combined with the style structures.
+/// NK_BUTTON_TRIGGER_ON_RELEASE    | Different platforms require button clicks occurring either on buttons being pressed (up to down) or released (down to up). By default this library will react on buttons being pressed, but if you define this it will only trigger if a button is released.
+/// NK_ZERO_COMMAND_MEMORY          | Defining this will zero out memory for each drawing command added to a drawing queue (inside nk_command_buffer_push). Zeroing command memory is very useful for fast checking (using memcmp) if command buffers are equal and avoid drawing frames when nothing on screen has changed since previous frame.

+///
+/// !!! WARNING
+///     The following flags if defined need to be defined for both header and implementation:

+/// --------------------------------|---------------------------------------
+/// NK_BUFFER_DEFAULT_INITIAL_SIZE  | Initial buffer size allocated by all buffers while using the default allocator functions included by defining NK_INCLUDE_DEFAULT_ALLOCATOR. If you don't want to allocate the default 4k memory then redefine it.
+/// NK_MAX_NUMBER_BUFFER            | Maximum buffer size for the conversion buffer between float and string Under normal circumstances this should be more than sufficient.
+/// NK_INPUT_MAX                    | Defines the max number of bytes which can be added as text input in one frame. Under normal circumstances this should be more than sufficient.

+///     - NK_INPUT_MAX
+///
+/// ### Dependencies
+/// Function    | Description
+/// ------------|---------------------------------------------------------------
+/// NK_ASSERT   | If you don't define this, nuklear will use <assert.h> with assert().
+/// NK_MEMSET   | You can define this to 'memset' or your own memset implementation replacement. If not nuklear will use its own version.
+/// NK_MEMCPY   | You can define this to 'memcpy' or your own memcpy implementation replacement. If not nuklear will use its own version.
+/// NK_SQRT     | You can define this to 'sqrt' or your own sqrt implementation replacement. If not nuklear will use its own slow and not highly accurate version.
+/// NK_SIN      | You can define this to 'sinf' or your own sine implementation replacement. If not nuklear will use its own approximation implementation.
+/// NK_COS      | You can define this to 'cosf' or your own cosine implementation replacement. If not nuklear will use its own approximation implementation.
+/// NK_STRTOD   | You can define this to `strtod` or your own string to double conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!).
+/// NK_DTOA     | You can define this to `dtoa` or your own double to string conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!).
+/// NK_VSNPRINTF| If you define `NK_INCLUDE_STANDARD_VARARGS` as well as `NK_INCLUDE_STANDARD_IO` and want to be safe define this to `vsnprintf` on compilers supporting later versions of C or C++. By default nuklear will check for your stdlib version in C as well as compiler version in C++. if `vsnprintf` is available it will define it to `vsnprintf` directly. If not defined and if you have older versions of C or C++ it will be defined to `vsprintf` which is unsafe.

+/*/// ### Input
+/// The input API is responsible for holding the current input state composed of
+/// mouse, key and text input states.
+/// It is worth noting that no direct OS or window handling is done in nuklear.
+/// Instead all input state has to be provided by platform specific code. This on one hand
+/// expects more work from the user and complicates usage but on the other hand
+/// provides simple abstraction over a big number of platforms, libraries and other
+/// already provided functionality.
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// nk_input_begin(&ctx);
+/// while (GetEvent(&evt)) {
+///     if (evt.type == MOUSE_MOVE)
+///         nk_input_motion(&ctx, evt.motion.x, evt.motion.y);
+///     else if (evt.type == [...]) {
+///         // [...]
+///     }
+/// } nk_input_end(&ctx);
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// #### Usage
+/// Input state needs to be provided to nuklear by first calling `nk_input_begin`
+/// which resets internal state like delta mouse position and button transistions.
+/// After `nk_input_begin` all current input state needs to be provided. This includes
+/// mouse motion, button and key pressed and released, text input and scrolling.
+/// Both event- or state-based input handling are supported by this API
+/// and should work without problems. Finally after all input state has been
+/// mirrored `nk_input_end` needs to be called to finish input process.
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// struct nk_context ctx;
+/// nk_init_xxx(&ctx, ...);

+ * =============================================================================*/
+/*/// ### Drawing
+/// This library was designed to be render backend agnostic so it does
+/// not draw anything to screen directly. Instead all drawn shapes, widgets
+/// are made of, are buffered into memory and make up a command queue.
+/// Each frame therefore fills the command buffer with draw commands
+/// that then need to be executed by the user and his own render backend.
+/// After that the command buffer needs to be cleared and a new frame can be
+/// started. It is probably important to note that the command buffer is the main
+/// drawing API and the optional vertex buffer API only takes this format and
+/// converts it into a hardware accessible format.
+///
+/// #### Usage
+/// To draw all draw commands accumulated over a frame you need your own render
+/// backend able to draw a number of 2D primitives. This includes at least
+/// filled and stroked rectangles, circles, text, lines, triangles and scissors.
+/// As soon as this criterion is met you can iterate over each draw command
+/// and execute each draw command in a interpreter like fashion:
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// const struct nk_command *cmd = 0;
+/// nk_foreach(cmd, &ctx) {
+///     switch (cmd->type) {
+///     case NK_COMMAND_LINE:
+///         your_draw_line_function(...)
+///         break;
+///     case NK_COMMAND_RECT
+///         your_draw_rect_function(...)
+///         break;
+///     case //...:
+///         //[...]
+///     }
+/// }
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// In program flow context draw commands need to be executed after input has been
+/// gathered and the complete UI with windows and their contained widgets have
+/// been executed and before calling `nk_clear` which frees all previously
+/// allocated draw commands.
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// struct nk_context ctx;
+/// nk_init_xxx(&ctx, ...);
+/// while (1) {
+///     Event evt;
+///     nk_input_begin(&ctx);
+///     while (GetEvent(&evt)) {
+///         if (evt.type == MOUSE_MOVE)
+///             nk_input_motion(&ctx, evt.motion.x, evt.motion.y);
+///         else if (evt.type == [...]) {
+///             [...]
+///         }
+///     }
+///     nk_input_end(&ctx);
+///     //
+///     // [...]
+///     //
+///     const struct nk_command *cmd = 0;
+///     nk_foreach(cmd, &ctx) {
+///     switch (cmd->type) {
+///     case NK_COMMAND_LINE:
+///         your_draw_line_function(...)
+///         break;
+///     case NK_COMMAND_RECT
+///         your_draw_rect_function(...)
+///         break;
+///     case ...:
+///         // [...]
+///     }
+///     nk_clear(&ctx);
+/// }
+/// nk_free(&ctx);
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// You probably noticed that you have to draw all of the UI each frame which is
+/// quite wasteful. While the actual UI updating loop is quite fast rendering
+/// without actually needing it is not. So there are multiple things you could do.
+///
+/// First is only update on input. This of course is only an option if your
+/// application only depends on the UI and does not require any outside calculations.
+/// If you actually only update on input make sure to update the UI two times each
+/// frame and call `nk_clear` directly after the first pass and only draw in
+/// the second pass. In addition it is recommended to also add additional timers
+/// to make sure the UI is not drawn more than a fixed number of frames per second.
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// struct nk_context ctx;
+/// nk_init_xxx(&ctx, ...);
+/// while (1) {
+///     // [...wait for input ]
+///     // [...do two UI passes ...]
+///     do_ui(...)
+///     nk_clear(&ctx);
+///     do_ui(...)
+///     //
+///     // draw
+///     const struct nk_command *cmd = 0;
+///     nk_foreach(cmd, &ctx) {
+///     switch (cmd->type) {
+///     case NK_COMMAND_LINE:
+///         your_draw_line_function(...)
+///         break;
+///     case NK_COMMAND_RECT
+///         your_draw_rect_function(...)
+///         break;
+///     case ...:
+///         //[...]
+///     }
+///     nk_clear(&ctx);
+/// }
+/// nk_free(&ctx);
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// The second probably more applicable trick is to only draw if anything changed.
+/// It is not really useful for applications with continuous draw loop but
+/// quite useful for desktop applications. To actually get nuklear to only
+/// draw on changes you first have to define `NK_ZERO_COMMAND_MEMORY` and
+/// allocate a memory buffer that will store each unique drawing output.
+/// After each frame you compare the draw command memory inside the library
+/// with your allocated buffer by memcmp. If memcmp detects differences
+/// you have to copy the command buffer into the allocated buffer
+/// and then draw like usual (this example uses fixed memory but you could
+/// use dynamically allocated memory).
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// //[... other defines ...]
+/// #define NK_ZERO_COMMAND_MEMORY
+/// #include "nuklear.h"
+/// //
+/// // setup context
+/// struct nk_context ctx;
+/// void *last = calloc(1,64*1024);
+/// void *buf = calloc(1,64*1024);
+/// nk_init_fixed(&ctx, buf, 64*1024);
+/// //
+/// // loop
+/// while (1) {
+///     // [...input...]
+///     // [...ui...]
+///     void *cmds = nk_buffer_memory(&ctx.memory);
+///     if (memcmp(cmds, last, ctx.memory.allocated)) {
+///         memcpy(last,cmds,ctx.memory.allocated);
+///         const struct nk_command *cmd = 0;
+///         nk_foreach(cmd, &ctx) {
+///             switch (cmd->type) {
+///             case NK_COMMAND_LINE:
+///                 your_draw_line_function(...)
+///                 break;
+///             case NK_COMMAND_RECT
+///                 your_draw_rect_function(...)
+///                 break;
+///             case ...:
+///                 // [...]

+///         }
+///     }
+///     nk_clear(&ctx);
+/// }
+/// nk_free(&ctx);
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// Finally while using draw commands makes sense for higher abstracted platforms like
+/// X11 and Win32 or drawing libraries it is often desirable to use graphics
+/// hardware directly. Therefore it is possible to just define
+/// `NK_INCLUDE_VERTEX_BUFFER_OUTPUT` which includes optional vertex output.
+/// To access the vertex output you first have to convert all draw commands into
+/// vertexes by calling `nk_convert` which takes in your preferred vertex format.

+ *
+ * =============================================================================
+/// ### Window
+/// Windows are the main persistent state used inside nuklear and are life time
+/// controlled by simply "retouching" (i.e. calling) each window each frame.
+/// All widgets inside nuklear can only be added inside the function pair `nk_begin_xxx`
+/// and `nk_end`. Calling any widgets outside these two functions will result in an
+/// assert in debug or no state change in release mode.<br /><br />
+///
+/// Each window holds frame persistent state like position, size, flags, state tables,
+/// and some garbage collected internal persistent widget state. Each window
+/// is linked into a window stack list which determines the drawing and overlapping
+/// order. The topmost window thereby is the currently active window.<br /><br />
+///
+/// To change window position inside the stack occurs either automatically by
+/// user input by being clicked on or programmatically by calling `nk_window_focus`.
+/// Windows by default are visible unless explicitly being defined with flag
+/// `NK_WINDOW_HIDDEN`, the user clicked the close button on windows with flag
+/// `NK_WINDOW_CLOSABLE` or if a window was explicitly hidden by calling
+/// `nk_window_show`. To explicitly close and destroy a window call `nk_window_close`.<br /><br />
+///
+/// #### Usage
+/// To create and keep a window you have to call one of the two `nk_begin_xxx`
+/// functions to start window declarations and `nk_end` at the end. Furthermore it
+/// is recommended to check the return value of `nk_begin_xxx` and only process
+/// widgets inside the window if the value is not 0. Either way you have to call
+/// `nk_end` at the end of window declarations. Furthermore, do not attempt to
+/// nest `nk_begin_xxx` calls which will hopefully result in an assert or if not
+/// in a segmentation fault.
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// if (nk_begin_xxx(...) {
+///     // [... widgets ...]
+/// }
+/// nk_end(ctx);
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// In the grand concept window and widget declarations need to occur after input
+/// handling and before drawing to screen. Not doing so can result in higher
+/// latency or at worst invalid behavior. Furthermore make sure that `nk_clear`
+/// is called at the end of the frame. While nuklear's default platform backends
+/// already call `nk_clear` for you if you write your own backend not calling
+/// `nk_clear` can cause asserts or even worse undefined behavior.
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// struct nk_context ctx;
+/// nk_init_xxx(&ctx, ...);
+/// while (1) {
+///     Event evt;
+///     nk_input_begin(&ctx);
+///     while (GetEvent(&evt)) {
+///         if (evt.type == MOUSE_MOVE)
+///             nk_input_motion(&ctx, evt.motion.x, evt.motion.y);
+///         else if (evt.type == [...]) {
+///             nk_input_xxx(...);
+///         }
+///     }
+///     nk_input_end(&ctx);
+///
+///     if (nk_begin_xxx(...) {
+///         //[...]
+///     }
+///     nk_end(ctx);
+///
+///     const struct nk_command *cmd = 0;

+ *
+ * =============================================================================
+/// ### Layouting
+/// Layouting in general describes placing widget inside a window with position and size.
+/// While in this particular implementation there are five different APIs for layouting
+/// each with different trade offs between control and ease of use. <br /><br />
+///
+/// All layouting methods in this library are based around the concept of a row.
+/// A row has a height the window content grows by and a number of columns and each
+/// layouting method specifies how each widget is placed inside the row.
+/// After a row has been allocated by calling a layouting functions and then
+/// filled with widgets will advance an internal pointer over the allocated row. <br /><br />
+///
+/// To actually define a layout you just call the appropriate layouting function
+/// and each subsequent widget call will place the widget as specified. Important
+/// here is that if you define more widgets then columns defined inside the layout
+/// functions it will allocate the next row without you having to make another layouting <br /><br />
+/// call.
+///
+/// Biggest limitation with using all these APIs outside the `nk_layout_space_xxx` API
+/// is that you have to define the row height for each. However the row height
+/// often depends on the height of the font. <br /><br />
+///
+/// To fix that internally nuklear uses a minimum row height that is set to the
+/// height plus padding of currently active font and overwrites the row height
+/// value if zero. <br /><br />
+///
+/// If you manually want to change the minimum row height then
+/// use nk_layout_set_min_row_height, and use nk_layout_reset_min_row_height to
+/// reset it back to be derived from font height. <br /><br />
+///
+/// Also if you change the font in nuklear it will automatically change the minimum
+/// row height for you and. This means if you change the font but still want
+/// a minimum row height smaller than the font you have to repush your value. <br /><br />
+///
+/// For actually more advanced UI I would even recommend using the `nk_layout_space_xxx`
+/// layouting method in combination with a cassowary constraint solver (there are
+/// some versions on github with permissive license model) to take over all control over widget
+/// layouting yourself. However for quick and dirty layouting using all the other layouting
+/// functions should be fine.
+///
+/// #### Usage
+/// 1.  __nk_layout_row_dynamic__<br /><br />
+///     The easiest layouting function is `nk_layout_row_dynamic`. It provides each
+///     widgets with same horizontal space inside the row and dynamically grows
+///     if the owning window grows in width. So the number of columns dictates
+///     the size of each widget dynamically by formula:
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     widget_width = (window_width - padding - spacing) * (1/colum_count)
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+///     Just like all other layouting APIs if you define more widget than columns this
+///     library will allocate a new row and keep all layouting parameters previously
+///     defined.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // first row with height: 30 composed of two widgets
+///         nk_layout_row_dynamic(&ctx, 30, 2);
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // second row with same parameter as defined above
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // third row uses 0 for height which will use auto layouting
+///         nk_layout_row_dynamic(&ctx, 0, 2);
+///         nk_widget(...);
+///         nk_widget(...);
+///     }
+///     nk_end(...);
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// 2.  __nk_layout_row_static__<br /><br />
+///     Another easy layouting function is `nk_layout_row_static`. It provides each
+///     widget with same horizontal pixel width inside the row and does not grow
+///     if the owning window scales smaller or bigger.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // first row with height: 30 composed of two widgets with width: 80
+///         nk_layout_row_static(&ctx, 30, 80, 2);
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // second row with same parameter as defined above
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // third row uses 0 for height which will use auto layouting
+///         nk_layout_row_static(&ctx, 0, 80, 2);
+///         nk_widget(...);
+///         nk_widget(...);
+///     }
+///     nk_end(...);
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// 3.  __nk_layout_row_xxx__<br /><br />
+///     A little bit more advanced layouting API are functions `nk_layout_row_begin`,
+///     `nk_layout_row_push` and `nk_layout_row_end`. They allow to directly
+///     specify each column pixel or window ratio in a row. It supports either
+///     directly setting per column pixel width or widget window ratio but not
+///     both. Furthermore it is a immediate mode API so each value is directly
+///     pushed before calling a widget. Therefore the layout is not automatically
+///     repeating like the last two layouting functions.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // first row with height: 25 composed of two widgets with width 60 and 40
+///         nk_layout_row_begin(ctx, NK_STATIC, 25, 2);
+///         nk_layout_row_push(ctx, 60);
+///         nk_widget(...);
+///         nk_layout_row_push(ctx, 40);
+///         nk_widget(...);
+///         nk_layout_row_end(ctx);
+///         //
+///         // second row with height: 25 composed of two widgets with window ratio 0.25 and 0.75
+///         nk_layout_row_begin(ctx, NK_DYNAMIC, 25, 2);
+///         nk_layout_row_push(ctx, 0.25f);
+///         nk_widget(...);
+///         nk_layout_row_push(ctx, 0.75f);
+///         nk_widget(...);
+///         nk_layout_row_end(ctx);
+///         //
+///         // third row with auto generated height: composed of two widgets with window ratio 0.25 and 0.75
+///         nk_layout_row_begin(ctx, NK_DYNAMIC, 0, 2);
+///         nk_layout_row_push(ctx, 0.25f);
+///         nk_widget(...);
+///         nk_layout_row_push(ctx, 0.75f);
+///         nk_widget(...);
+///         nk_layout_row_end(ctx);
+///     }
+///     nk_end(...);
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// 4.  __nk_layout_row__<br /><br />
+///     The array counterpart to API nk_layout_row_xxx is the single nk_layout_row
+///     functions. Instead of pushing either pixel or window ratio for every widget
+///     it allows to define it by array. The trade of for less control is that
+///     `nk_layout_row` is automatically repeating. Otherwise the behavior is the
+///     same.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // two rows with height: 30 composed of two widgets with width 60 and 40
+///         const float size[] = {60,40};
+///         nk_layout_row(ctx, NK_STATIC, 30, 2, ratio);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // two rows with height: 30 composed of two widgets with window ratio 0.25 and 0.75
+///         const float ratio[] = {0.25, 0.75};
+///         nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // two rows with auto generated height composed of two widgets with window ratio 0.25 and 0.75
+///         const float ratio[] = {0.25, 0.75};
+///         nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///     }
+///     nk_end(...);
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// 5.  __nk_layout_row_template_xxx__<br /><br />
+///     The most complex and second most flexible API is a simplified flexbox version without
+///     line wrapping and weights for dynamic widgets. It is an immediate mode API but
+///     unlike `nk_layout_row_xxx` it has auto repeat behavior and needs to be called
+///     before calling the templated widgets.
+///     The row template layout has three different per widget size specifier. The first
+///     one is the `nk_layout_row_template_push_static`  with fixed widget pixel width.
+///     They do not grow if the row grows and will always stay the same.
+///     The second size specifier is `nk_layout_row_template_push_variable`
+///     which defines a minimum widget size but it also can grow if more space is available
+///     not taken by other widgets.
+///     Finally there are dynamic widgets with `nk_layout_row_template_push_dynamic`
+///     which are completely flexible and unlike variable widgets can even shrink
+///     to zero if not enough space is provided.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // two rows with height: 30 composed of three widgets
+///         nk_layout_row_template_begin(ctx, 30);
+///         nk_layout_row_template_push_dynamic(ctx);
+///         nk_layout_row_template_push_variable(ctx, 80);
+///         nk_layout_row_template_push_static(ctx, 80);
+///         nk_layout_row_template_end(ctx);
+///         //
+///         // first row
+///         nk_widget(...); // dynamic widget can go to zero if not enough space
+///         nk_widget(...); // variable widget with min 80 pixel but can grow bigger if enough space
+///         nk_widget(...); // static widget with fixed 80 pixel width
+///         //
+///         // second row same layout
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///     }
+///     nk_end(...);
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// 6.  __nk_layout_space_xxx__<br /><br />
+///     Finally the most flexible API directly allows you to place widgets inside the
+///     window. The space layout API is an immediate mode API which does not support
+///     row auto repeat and directly sets position and size of a widget. Position
+///     and size hereby can be either specified as ratio of allocated space or
+///     allocated space local position and pixel size. Since this API is quite
+///     powerful there are a number of utility functions to get the available space
+///     and convert between local allocated space and screen space.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // static row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered)
+///         nk_layout_space_begin(ctx, NK_STATIC, 500, INT_MAX);
+///         nk_layout_space_push(ctx, nk_rect(0,0,150,200));
+///         nk_widget(...);
+///         nk_layout_space_push(ctx, nk_rect(200,200,100,200));

+ *                                  GROUP
+ *
+ * =============================================================================
+/// ### Groups
+/// Groups are basically windows inside windows. They allow to subdivide space
+/// in a window to layout widgets as a group. Almost all more complex widget
+/// layouting requirements can be solved using groups and basic layouting
+/// fuctionality. Groups just like windows are identified by an unique name and
+/// internally keep track of scrollbar offsets by default. However additional
+/// versions are provided to directly manage the scrollbar.
+///
+/// #### Usage
+/// To create a group you have to call one of the three `nk_group_begin_xxx`
+/// functions to start group declarations and `nk_group_end` at the end. Furthermore it
+/// is required to check the return value of `nk_group_begin_xxx` and only process
+/// widgets inside the window if the value is not 0.
+/// Nesting groups is possible and even encouraged since many layouting schemes
+/// can only be achieved by nesting. Groups, unlike windows, need `nk_group_end`
+/// to be only called if the corosponding `nk_group_begin_xxx` call does not return 0:
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// if (nk_group_begin_xxx(ctx, ...) {
+///     // [... widgets ...]
+///     nk_group_end(ctx);
+/// }
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// In the grand concept groups can be called after starting a window
+/// with `nk_begin_xxx` and before calling `nk_end`:
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// struct nk_context ctx;
+/// nk_init_xxx(&ctx, ...);
+/// while (1) {
+///     // Input
+///     Event evt;
+///     nk_input_begin(&ctx);
+///     while (GetEvent(&evt)) {
+///         if (evt.type == MOUSE_MOVE)
+///             nk_input_motion(&ctx, evt.motion.x, evt.motion.y);
+///         else if (evt.type == [...]) {
+///             nk_input_xxx(...);
+///         }
+///     }
+///     nk_input_end(&ctx);
+///     //
+///     // Window
+///     if (nk_begin_xxx(...) {
+///         // [...widgets...]
+///         nk_layout_row_dynamic(...);
+///         if (nk_group_begin_xxx(ctx, ...) {
+///             //[... widgets ...]
+///             nk_group_end(ctx);
+///         }
+///     }
+///     nk_end(ctx);
+///     //
+///     // Draw
+///     const struct nk_command *cmd = 0;
+///     nk_foreach(cmd, &ctx) {
+///     switch (cmd->type) {

+ * ============================================================================= 
+/// ### Tree
+/// Trees represent two different concept. First the concept of a collapsable
+/// UI section that can be either in a hidden or visibile state. They allow the UI
+/// user to selectively minimize the current set of visible UI to comprehend.
+/// The second concept are tree widgets for visual UI representation of trees.<br /><br />
+///
+/// Trees thereby can be nested for tree representations and multiple nested
+/// collapsable UI sections. All trees are started by calling of the
+/// `nk_tree_xxx_push_tree` functions and ended by calling one of the
+/// `nk_tree_xxx_pop_xxx()` functions. Each starting functions takes a title label
+/// and optionally an image to be displayed and the initial collapse state from
+/// the nk_collapse_states section.<br /><br />
+///
+/// The runtime state of the tree is either stored outside the library by the caller
+/// or inside which requires a unique ID. The unique ID can either be generated
+/// automatically from `__FILE__` and `__LINE__` with function `nk_tree_push`,
+/// by `__FILE__` and a user provided ID generated for example by loop index with
+/// function `nk_tree_push_id` or completely provided from outside by user with
+/// function `nk_tree_push_hashed`.
+///
+/// #### Usage
+/// To create a tree you have to call one of the seven `nk_tree_xxx_push_xxx`
+/// functions to start a collapsable UI section and `nk_tree_xxx_pop` to mark the
+/// end.
+/// Each starting function will either return `false(0)` if the tree is collapsed
+/// or hidden and therefore does not need to be filled with content or `true(1)`
+/// if visible and required to be filled.
+///
+/// !!! Note
+///     The tree header does not require and layouting function and instead
+///     calculates a auto height based on the currently used font size
+///
+/// The tree ending functions only need to be called if the tree content is
+/// actually visible. So make sure the tree push function is guarded by `if`
+/// and the pop call is only taken if the tree is visible.
+///

+/// ### Properties
+/// Properties are the main value modification widgets in Nuklear. Changing a value
+/// can be achieved by dragging, adding/removing incremental steps on button click
+/// or by directly typing a number.
+///
+/// #### Usage
+/// Each property requires a unique name for identifaction that is also used for
+/// displaying a label. If you want to use the same name multiple times make sure
+/// add a '#' before your name. The '#' will not be shown but will generate a
+/// unique ID. Each propery also takes in a minimum and maximum value. If you want
+/// to make use of the complete number range of a type just use the provided
+/// type limits from `limits.h`. For example `INT_MIN` and `INT_MAX` for
+/// `nk_property_int` and `nk_propertyi`. In additional each property takes in
+/// a increment value that will be added or subtracted if either the increment
+/// decrement button is clicked. Finally there is a value for increment per pixel
+/// dragged that is added or subtracted from the value.

+/*  Font handling in this library was designed to be quite customizable and lets
+    you decide what you want to use and what you want to provide. There are three
+    different ways to use the font atlas. The first two will use your font
+    handling scheme and only requires essential data to run nuklear. The next
+    slightly more advanced features is font handling with vertex buffer output.
+    Finally the most complex API wise is using nuklear's font baking API.
+
+    1.) Using your own implementation without vertex buffer output
+    --------------------------------------------------------------
+    So first up the easiest way to do font handling is by just providing a
+    `nk_user_font` struct which only requires the height in pixel of the used
+    font and a callback to calculate the width of a string. This way of handling
+    fonts is best fitted for using the normal draw shape command API where you
+    do all the text drawing yourself and the library does not require any kind
+    of deeper knowledge about which font handling mechanism you use.
+    IMPORTANT: the `nk_user_font` pointer provided to nuklear has to persist
+    over the complete life time! I know this sucks but it is currently the only
+    way to switch between fonts.
+
+        float your_text_width_calculation(nk_handle handle, float height, const char *text, int len)
+        {
+            your_font_type *type = handle.ptr;
+            float text_width = ...;
+            return text_width;
+        }
+
+        struct nk_user_font font;
+        font.userdata.ptr = &your_font_class_or_struct;
+        font.height = your_font_height;
+        font.width = your_text_width_calculation;
+
+        struct nk_context ctx;
+        nk_init_default(&ctx, &font);
+
+    2.) Using your own implementation with vertex buffer output
+    --------------------------------------------------------------
+    While the first approach works fine if you don't want to use the optional
+    vertex buffer output it is not enough if you do. To get font handling working
+    for these cases you have to provide two additional parameters inside the
+    `nk_user_font`. First a texture atlas handle used to draw text as subimages
+    of a bigger font atlas texture and a callback to query a character's glyph
+    information (offset, size, ...). So it is still possible to provide your own
+    font and use the vertex buffer output.
+
+        float your_text_width_calculation(nk_handle handle, float height, const char *text, int len)
+        {
+            your_font_type *type = handle.ptr;
+            float text_width = ...;
+            return text_width;
+        }
+        void query_your_font_glyph(nk_handle handle, float font_height, struct nk_user_font_glyph *glyph, nk_rune codepoint, nk_rune next_codepoint)
+        {
+            your_font_type *type = handle.ptr;
+            glyph.width = ...;
+            glyph.height = ...;
+            glyph.xadvance = ...;
+            glyph.uv[0].x = ...;
+            glyph.uv[0].y = ...;
+            glyph.uv[1].x = ...;
+            glyph.uv[1].y = ...;
+            glyph.offset.x = ...;
+            glyph.offset.y = ...;
+        }
+
+        struct nk_user_font font;
+        font.userdata.ptr = &your_font_class_or_struct;
+        font.height = your_font_height;
+        font.width = your_text_width_calculation;
+        font.query = query_your_font_glyph;
+        font.texture.id = your_font_texture;
+
+        struct nk_context ctx;
+        nk_init_default(&ctx, &font);
+
+    3.) Nuklear font baker
+    ------------------------------------
+    The final approach if you do not have a font handling functionality or don't
+    want to use it in this library is by using the optional font baker.
+    The font baker APIs can be used to create a font plus font atlas texture
+    and can be used with or without the vertex buffer output.
+
+    It still uses the `nk_user_font` struct and the two different approaches
+    previously stated still work. The font baker is not located inside
+    `nk_context` like all other systems since it can be understood as more of
+    an extension to nuklear and does not really depend on any `nk_context` state.
+
+    Font baker need to be initialized first by one of the nk_font_atlas_init_xxx
+    functions. If you don't care about memory just call the default version
+    `nk_font_atlas_init_default` which will allocate all memory from the standard library.
+    If you want to control memory allocation but you don't care if the allocated
+    memory is temporary and therefore can be freed directly after the baking process
+    is over or permanent you can call `nk_font_atlas_init`.
+
+    After successfully initializing the font baker you can add Truetype(.ttf) fonts from
+    different sources like memory or from file by calling one of the `nk_font_atlas_add_xxx`.
+    functions. Adding font will permanently store each font, font config and ttf memory block(!)
+    inside the font atlas and allows to reuse the font atlas. If you don't want to reuse
+    the font baker by for example adding additional fonts you can call
+    `nk_font_atlas_cleanup` after the baking process is over (after calling nk_font_atlas_end).
+
+    As soon as you added all fonts you wanted you can now start the baking process
+    for every selected glyph to image by calling `nk_font_atlas_bake`.
+    The baking process returns image memory, width and height which can be used to
+    either create your own image object or upload it to any graphics library.
+    No matter which case you finally have to call `nk_font_atlas_end` which
+    will free all temporary memory including the font atlas image so make sure
+    you created our texture beforehand. `nk_font_atlas_end` requires a handle
+    to your font texture or object and optionally fills a `struct nk_draw_null_texture`
+    which can be used for the optional vertex output. If you don't want it just
+    set the argument to `NULL`.
+
+    At this point you are done and if you don't want to reuse the font atlas you
+    can call `nk_font_atlas_cleanup` to free all truetype blobs and configuration
+    memory. Finally if you don't use the font atlas and any of it's fonts anymore
+    you need to call `nk_font_atlas_clear` to free all memory still being used.
+
+        struct nk_font_atlas atlas;
+        nk_font_atlas_init_default(&atlas);
+        nk_font_atlas_begin(&atlas);
+        nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, 0);
+        nk_font *font2 = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font2.ttf", 16, 0);
+        const void* img = nk_font_atlas_bake(&atlas, &img_width, &img_height, NK_FONT_ATLAS_RGBA32);
+        nk_font_atlas_end(&atlas, nk_handle_id(texture), 0);
+
+        struct nk_context ctx;
+        nk_init_default(&ctx, &font->handle);
+        while (1) {
+
+        }
+        nk_font_atlas_clear(&atlas);
+
+    The font baker API is probably the most complex API inside this library and
+    I would suggest reading some of my examples `example/` to get a grip on how
+    to use the font atlas. There are a number of details I left out. For example
+    how to merge fonts, configure a font with `nk_font_config` to use other languages,
+    use another texture coordinate format and a lot more:
+
+        struct nk_font_config cfg = nk_font_config(font_pixel_height);
+        cfg.merge_mode = nk_false or nk_true;
+        cfg.range = nk_font_korean_glyph_ranges();
+        cfg.coord_type = NK_COORD_PIXEL;
+        nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, &cfg);

+ *                          MEMORY BUFFER
+ *
+ * ===============================================================*/
+/*  A basic (double)-buffer with linear allocation and resetting as only
+    freeing policy. The buffer's main purpose is to control all memory management
+    inside the GUI toolkit and still leave memory control as much as possible in
+    the hand of the user while also making sure the library is easy to use if
+    not as much control is needed.
+    In general all memory inside this library can be provided from the user in
+    three different ways.
+
+    The first way and the one providing most control is by just passing a fixed
+    size memory block. In this case all control lies in the hand of the user
+    since he can exactly control where the memory comes from and how much memory
+    the library should consume. Of course using the fixed size API removes the
+    ability to automatically resize a buffer if not enough memory is provided so
+    you have to take over the resizing. While being a fixed sized buffer sounds
+    quite limiting, it is very effective in this library since the actual memory
+    consumption is quite stable and has a fixed upper bound for a lot of cases.
+
+    If you don't want to think about how much memory the library should allocate
+    at all time or have a very dynamic UI with unpredictable memory consumption
+    habits but still want control over memory allocation you can use the dynamic
+    allocator based API. The allocator consists of two callbacks for allocating
+    and freeing memory and optional userdata so you can plugin your own allocator.
+
+    The final and easiest way can be used by defining
+    NK_INCLUDE_DEFAULT_ALLOCATOR which uses the standard library memory
+    allocation functions malloc and free and takes over complete control over
+    memory in this library.

+ *
+ * ===============================================================*/
+/* Editing text in this library is handled by either `nk_edit_string` or
+ * `nk_edit_buffer`. But like almost everything in this library there are multiple
+ * ways of doing it and a balance between control and ease of use with memory
+ * as well as functionality controlled by flags.
+ *
+ * This library generally allows three different levels of memory control:
+ * First of is the most basic way of just providing a simple char array with
+ * string length. This method is probably the easiest way of handling simple
+ * user text input. Main upside is complete control over memory while the biggest
+ * downside in comparison with the other two approaches is missing undo/redo.
+ *
+ * For UIs that require undo/redo the second way was created. It is based on
+ * a fixed size nk_text_edit struct, which has an internal undo/redo stack.
+ * This is mainly useful if you want something more like a text editor but don't want
+ * to have a dynamically growing buffer.
+ *
+ * The final way is using a dynamically growing nk_text_edit struct, which
+ * has both a default version if you don't care where memory comes from and an
+ * allocator version if you do. While the text editor is quite powerful for its
+ * complexity I would not recommend editing gigabytes of data with it.
+ * It is rather designed for uses cases which make sense for a GUI library not for
+ * an full blown text editor.

+ *
+ *                          DRAWING
+ *
+ * ===============================================================*/
+/*  This library was designed to be render backend agnostic so it does
+    not draw anything to screen. Instead all drawn shapes, widgets
+    are made of, are buffered into memory and make up a command queue.
+    Each frame therefore fills the command buffer with draw commands
+    that then need to be executed by the user and his own render backend.
+    After that the command buffer needs to be cleared and a new frame can be
+    started. It is probably important to note that the command buffer is the main
+    drawing API and the optional vertex buffer API only takes this format and
+    converts it into a hardware accessible format.
+
+    To use the command queue to draw your own widgets you can access the
+    command buffer of each window by calling `nk_window_get_canvas` after
+    previously having called `nk_begin`:
+
+        void draw_red_rectangle_widget(struct nk_context *ctx)
+        {
+            struct nk_command_buffer *canvas;
+            struct nk_input *input = &ctx->input;
+            canvas = nk_window_get_canvas(ctx);
+
+            struct nk_rect space;
+            enum nk_widget_layout_states state;
+            state = nk_widget(&space, ctx);
+            if (!state) return;
+
+            if (state != NK_WIDGET_ROM)
+                update_your_widget_by_user_input(...);
+            nk_fill_rect(canvas, space, 0, nk_rgb(255,0,0));
+        }
+
+        if (nk_begin(...)) {
+            nk_layout_row_dynamic(ctx, 25, 1);
+            draw_red_rectangle_widget(ctx);
+        }
+        nk_end(..)
+
+    Important to know if you want to create your own widgets is the `nk_widget`
+    call. It allocates space on the panel reserved for this widget to be used,
+    but also returns the state of the widget space. If your widget is not seen and does
+    not have to be updated it is '0' and you can just return. If it only has
+    to be drawn the state will be `NK_WIDGET_ROM` otherwise you can do both
+    update and draw your widget. The reason for separating is to only draw and
+    update what is actually necessary which is crucial for performance.

+    probably not faster it is still fast and accurate enough for
+    nuklear's use cases. IMPORTANT: this requires float format IEEE 754
+
+    Sine/Cosine
+    -----------
+    All constants inside both function are generated Remez's minimax
+    approximations for value range 0...2*PI. The reason why I decided to
+    approximate exactly that range is that nuklear only needs sine and
+    cosine to generate circles which only requires that exact range.
+    In addition I used Remez instead of Taylor for additional precision:
+    www.lolengine.net/blog/2011/12/21/better-function-approximations.
+
+    The tool I used to generate constants for both sine and cosine
+    (it can actually approximate a lot more functions) can be
+    found here: www.lolengine.net/wiki/oss/lolremez

+/// - 2018/04/01 (4.00.0) - BREAKING CHANGE: nk_draw_list_clear no longer tries to
+///                         clear provided buffers. So make sure to either free
+///                         or clear each passed buffer after calling nk_convert.
+/// - 2018/02/23 (3.00.6) - Fixed slider dragging behavior
+/// - 2018/01/31 (3.00.5) - Fixed overcalculation of cursor data in font baking process
+/// - 2018/01/31 (3.00.4) - Removed name collision with stb_truetype
+/// - 2018/01/28 (3.00.3) - Fixed panel window border drawing bug
+/// - 2018/01/12 (3.00.2) - Added `nk_group_begin_titled` for separed group identifier and title
+/// - 2018/01/07 (3.00.1) - Started to change documentation style
+/// - 2018/01/05 (3.00.0) - BREAKING CHANGE: The previous color picker API was broken
+///                        because of conversions between float and byte color representation.
+///                        Color pickers now use floating point values to represent
+///                        HSV values. To get back the old behavior I added some additional
+///                        color conversion functions to cast between nk_color and
+///                        nk_colorf.

+/// - 2017/09/14 (2.00.1) - Fixed window closing behavior
+/// - 2017/09/14 (2.00.0) - BREAKING CHANGE: Modifing window position and size funtions now
+///                        require the name of the window and must happen outside the window
+///                        building process (between function call nk_begin and nk_end).
+/// - 2017/09/11 (1.40.9) - Fixed window background flag if background window is declared last
+/// - 2017/08/27 (1.40.8) - Fixed `nk_item_is_any_active` for hidden windows
+/// - 2017/08/27 (1.40.7) - Fixed window background flag
+/// - 2017/07/07 (1.40.6) - Fixed missing clipping rect check for hovering/clicked
+///                        query for widgets
+/// - 2017/07/07 (1.40.5) - Fixed drawing bug for vertex output for lines and stroked
+///                        and filled rectangles
+/// - 2017/07/07 (1.40.4) - Fixed bug in nk_convert trying to add windows that are in
+///                        process of being destroyed.
+/// - 2017/07/07 (1.40.3) - Fixed table internal bug caused by storing table size in
+///                        window instead of directly in table.
+/// - 2017/06/30 (1.40.2) - Removed unneeded semicolon in C++ NK_ALIGNOF macro
+/// - 2017/06/30 (1.40.1) - Fixed drawing lines smaller or equal zero
+/// - 2017/06/08 (1.40.0) - Removed the breaking part of last commit. Auto layout now only
+///                        comes in effect if you pass in zero was row height argument
+/// - 2017/06/08 (1.40.0) - BREAKING CHANGE: while not directly API breaking it will change
+///                        how layouting works. From now there will be an internal minimum
+///                        row height derived from font height. If you need a row smaller than
+///                        that you can directly set it by `nk_layout_set_min_row_height` and
+///                        reset the value back by calling `nk_layout_reset_min_row_height.
+/// - 2017/06/08 (1.39.1) - Fixed property text edit handling bug caused by past `nk_widget` fix
+/// - 2017/06/08 (1.39.0) - Added function to retrieve window space without calling a nk_layout_xxx function
+/// - 2017/06/06 (1.38.5) - Fixed `nk_convert` return flag for command buffer
+/// - 2017/05/23 (1.38.4) - Fixed activation behavior for widgets partially clipped
+/// - 2017/05/10 (1.38.3) - Fixed wrong min window size mouse scaling over boundries
+/// - 2017/05/09 (1.38.2) - Fixed vertical scrollbar drawing with not enough space
+/// - 2017/05/09 (1.38.1) - Fixed scaler dragging behavior if window size hits minimum size
+/// - 2017/05/06 (1.38.0) - Added platform double-click support
+/// - 2017/04/20 (1.37.1) - Fixed key repeat found inside glfw demo backends

+/// - 2017/03/25 (1.35.2) - Fixed popup overlapping for `NK_WINDOW_BACKGROUND` windows
+/// - 2017/03/25 (1.35.1) - Fixed windows closing behavior

+/// - 2017/01/24 (1.33.0) - Added programatic way of remove edit focus
+/// - 2017/01/24 (1.32.3) - Fixed wrong define for basic type definitions for windows
+/// - 2017/01/21 (1.32.2) - Fixed input capture from hidden or closed windows
+/// - 2017/01/21 (1.32.1) - Fixed slider behavior and drawing
+/// - 2017/01/13 (1.32.0) - Added flag to put scaler into the bottom left corner
+/// - 2017/01/13 (1.31.0) - Added additional row layouting method to combine both
+///                        dynamic and static widgets.
+/// - 2016/12/31 (1.30.0) - Extended scrollbar offset from 16-bit to 32-bit
+/// - 2016/12/31 (1.29.2)- Fixed closing window bug of minimized windows
+/// - 2016/12/03 (1.29.1)- Fixed wrapped text with no seperator and C89 error
+/// - 2016/12/03 (1.29.0) - Changed text wrapping to process words not characters
+/// - 2016/11/22 (1.28.6)- Fixed window minimized closing bug
+/// - 2016/11/19 (1.28.5)- Fixed abstract combo box closing behavior
+/// - 2016/11/19 (1.28.4)- Fixed tooltip flickering
+/// - 2016/11/19 (1.28.3)- Fixed memory leak caused by popup repeated closing
+/// - 2016/11/18 (1.28.2)- Fixed memory leak caused by popup panel allocation
+/// - 2016/11/10 (1.28.1)- Fixed some warnings and C++ error
+/// - 2016/11/10 (1.28.0)- Added additional `nk_button` versions which allows to directly
+///                        pass in a style struct to change buttons visual.
+/// - 2016/11/10 (1.27.0)- Added additional 'nk_tree' versions to support external state
+///                        storage. Just like last the `nk_group` commit the main
+///                        advantage is that you optionally can minimize nuklears runtime
+///                        memory consumption or handle hash collisions.
+/// - 2016/11/09 (1.26.0)- Added additional `nk_group` version to support external scrollbar
+///                        offset storage. Main advantage is that you can externalize
+///                        the memory management for the offset. It could also be helpful
+///                        if you have a hash collision in `nk_group_begin` but really
+///                        want the name. In addition I added `nk_list_view` which allows
+///                        to draw big lists inside a group without actually having to
+///                        commit the whole list to nuklear (issue #269).
+/// - 2016/10/30 (1.25.1)- Fixed clipping rectangle bug inside `nk_draw_list`
+/// - 2016/10/29 (1.25.0)- Pulled `nk_panel` memory management into nuklear and out of
+///                        the hands of the user. From now on users don't have to care
+///                        about panels unless they care about some information. If you
+///                        still need the panel just call `nk_window_get_panel`.
+/// - 2016/10/21 (1.24.0)- Changed widget border drawing to stroked rectangle from filled
+///                        rectangle for less overdraw and widget background transparency.
+/// - 2016/10/18 (1.23.0)- Added `nk_edit_focus` for manually edit widget focus control
+/// - 2016/09/29 (1.22.7)- Fixed deduction of basic type in non `<stdint.h>` compilation
+/// - 2016/09/29 (1.22.6)- Fixed edit widget UTF-8 text cursor drawing bug
+/// - 2016/09/28 (1.22.5)- Fixed edit widget UTF-8 text appending/inserting/removing
+/// - 2016/09/28 (1.22.4)- Fixed drawing bug inside edit widgets which offset all text
+///                        text in every edit widget if one of them is scrolled.
+/// - 2016/09/28 (1.22.3)- Fixed small bug in edit widgets if not active. The wrong
+///                        text length is passed. It should have been in bytes but
+///                        was passed as glyphes.
+/// - 2016/09/20 (1.22.2)- Fixed color button size calculation
+/// - 2016/09/20 (1.22.1)- Fixed some `nk_vsnprintf` behavior bugs and removed
+///                        `<stdio.h>` again from `NK_INCLUDE_STANDARD_VARARGS`.
+/// - 2016/09/18 (1.22.0)- C89 does not support vsnprintf only C99 and newer as well
+///                        as C++11 and newer. In addition to use vsnprintf you have
+///                        to include <stdio.h>. So just defining `NK_INCLUDE_STD_VAR_ARGS`
+///                        is not enough. That behavior is now fixed. By default if
+///                        both varargs as well as stdio is selected I try to use
+///                        vsnprintf if not possible I will revert to vsprintf. If
+///                        varargs but not stdio was defined I will use my own function.
+/// - 2016/09/15 (1.21.2)- Fixed panel `close` behavior for deeper panel levels
+/// - 2016/09/15 (1.21.1)- Fixed C++ errors and wrong argument to `nk_panel_get_xxxx`
+/// - 2016/09/13 (1.21.0) - !BREAKING! Fixed nonblocking popup behavior in menu, combo,
+///                        and contextual which prevented closing in y-direction if
+///                        popup did not reach max height.
+///                        In addition the height parameter was changed into vec2
+///                        for width and height to have more control over the popup size.
+/// - 2016/09/13 (1.20.3) - Cleaned up and extended type selection
+/// - 2016/09/13 (1.20.2)- Fixed slider behavior hopefully for the last time. This time
+///                        all calculation are correct so no more hackery.
+/// - 2016/09/13 (1.20.1)- Internal change to divide window/panel flags into panel flags and types.
+///                        Suprisinly spend years in C and still happened to confuse types
+///                        with flags. Probably something to take note.
+/// - 2016/09/08 (1.20.0)- Added additional helper function to make it easier to just
+///                        take the produced buffers from `nk_convert` and unplug the
+///                        iteration process from `nk_context`. So now you can
+///                        just use the vertex,element and command buffer + two pointer
+///                        inside the command buffer retrieved by calls `nk__draw_begin`
+///                        and `nk__draw_end` and macro `nk_draw_foreach_bounded`.
+/// - 2016/09/08 (1.19.0)- Added additional asserts to make sure every `nk_xxx_begin` call
+///                        for windows, popups, combobox, menu and contextual is guarded by
+///                        `if` condition and does not produce false drawing output.
+/// - 2016/09/08 (1.18.0)- Changed confusing name for `NK_SYMBOL_RECT_FILLED`, `NK_SYMBOL_RECT`
+///                        to hopefully easier to understand `NK_SYMBOL_RECT_FILLED` and
+///                        `NK_SYMBOL_RECT_OUTLINE`.
+/// - 2016/09/08 (1.17.0)- Changed confusing name for `NK_SYMBOL_CIRLCE_FILLED`, `NK_SYMBOL_CIRCLE`
+///                        to hopefully easier to understand `NK_SYMBOL_CIRCLE_FILLED` and
+///                        `NK_SYMBOL_CIRCLE_OUTLINE`.
+/// - 2016/09/08 (1.16.0)- Added additional checks to select correct types if `NK_INCLUDE_FIXED_TYPES`
+///                        is not defined by supporting the biggest compiler GCC, clang and MSVC.
+/// - 2016/09/07 (1.15.3)- Fixed `NK_INCLUDE_COMMAND_USERDATA` define to not cause an error
+/// - 2016/09/04 (1.15.2)- Fixed wrong combobox height calculation
+/// - 2016/09/03 (1.15.1)- Fixed gaps inside combo boxes in OpenGL
+/// - 2016/09/02 (1.15.0) - Changed nuklear to not have any default vertex layout and
+///                        instead made it user provided. The range of types to convert
+///                        to is quite limited at the moment, but I would be more than
+///                        happy to accept PRs to add additional.
+/// - 2016/08/30 (1.14.2) - Removed unused variables
+/// - 2016/08/30 (1.14.1) - Fixed C++ build errors
+/// - 2016/08/30 (1.14.0) - Removed mouse dragging from SDL demo since it does not work correctly
+/// - 2016/08/30 (1.13.4) - Tweaked some default styling variables
+/// - 2016/08/30 (1.13.3) - Hopefully fixed drawing bug in slider, in general I would
+///                        refrain from using slider with a big number of steps.
+/// - 2016/08/30 (1.13.2) - Fixed close and minimize button which would fire even if the
+///                        window was in Read Only Mode.
+/// - 2016/08/30 (1.13.1) - Fixed popup panel padding handling which was previously just
+///                        a hack for combo box and menu.
+/// - 2016/08/30 (1.13.0) - Removed `NK_WINDOW_DYNAMIC` flag from public API since
+///                        it is bugged and causes issues in window selection.
+/// - 2016/08/30 (1.12.0) - Removed scaler size. The size of the scaler is now
+///                        determined by the scrollbar size
+/// - 2016/08/30 (1.11.2) - Fixed some drawing bugs caused by changes from 1.11
+/// - 2016/08/30 (1.11.1) - Fixed overlapping minimized window selection
+/// - 2016/08/30 (1.11.0) - Removed some internal complexity and overly complex code
+///                        handling panel padding and panel border.
+/// - 2016/08/29 (1.10.0) - Added additional height parameter to `nk_combobox_xxx`
+/// - 2016/08/29 (1.10.0) - Fixed drawing bug in dynamic popups
+/// - 2016/08/29 (1.10.0) - Added experimental mouse scrolling to popups, menus and comboboxes
+/// - 2016/08/26 (1.10.0) - Added window name string prepresentation to account for
+///                        hash collisions. Currently limited to NK_WINDOW_MAX_NAME
+///                        which in term can be redefined if not big enough.
+/// - 2016/08/26 (1.10.0) - Added stacks for temporary style/UI changes in code
+/// - 2016/08/25 (1.10.0) - Changed `nk_input_is_key_pressed` and 'nk_input_is_key_released'
+///                        to account for key press and release happening in one frame.
+/// - 2016/08/25 (1.10.0) - Added additional nk_edit flag to directly jump to the end on activate
+/// - 2016/08/17 (1.09.6)- Removed invalid check for value zero in nk_propertyx
+/// - 2016/08/16 (1.09.5)- Fixed ROM mode for deeper levels of popup windows parents.
+/// - 2016/08/15 (1.09.4)- Editbox are now still active if enter was pressed with flag
+///                        `NK_EDIT_SIG_ENTER`. Main reasoning is to be able to keep
+///                        typing after commiting.
+/// - 2016/08/15 (1.09.4)- Removed redundant code
+/// - 2016/08/15 (1.09.4)- Fixed negative numbers in `nk_strtoi` and remove unused variable
+/// - 2016/08/15 (1.09.3)- Fixed `NK_WINDOW_BACKGROUND` flag behavior to select a background
+///                        window only as selected by hovering and not by clicking.
+/// - 2016/08/14 (1.09.2)- Fixed a bug in font atlas which caused wrong loading
+///                        of glyphes for font with multiple ranges.
+/// - 2016/08/12 (1.09.1)- Added additional function to check if window is currently
+///                        hidden and therefore not visible.
+/// - 2016/08/12 (1.09.1)- nk_window_is_closed now queries the correct flag `NK_WINDOW_CLOSED`
+///                        instead of the old flag `NK_WINDOW_HIDDEN`
+/// - 2016/08/09 (1.09.0) - Added additional double version to nk_property and changed
+///                        the underlying implementation to not cast to float and instead
+///                        work directly on the given values.
+/// - 2016/08/09 (1.08.0) - Added additional define to overwrite library internal
+///                        floating pointer number to string conversion for additional
+///                        precision.
+/// - 2016/08/09 (1.08.0) - Added additional define to overwrite library internal
+///                        string to floating point number conversion for additional
+///                        precision.
+/// - 2016/08/08 (1.07.2)- Fixed compiling error without define NK_INCLUDE_FIXED_TYPE
+/// - 2016/08/08 (1.07.1)- Fixed possible floating point error inside `nk_widget` leading
+///                        to wrong wiget width calculation which results in widgets falsly
+///                        becomming tagged as not inside window and cannot be accessed.
+/// - 2016/08/08 (1.07.0) - Nuklear now differentiates between hiding a window (NK_WINDOW_HIDDEN) and
+///                        closing a window (NK_WINDOW_CLOSED). A window can be hidden/shown
+///                        by using `nk_window_show` and closed by either clicking the close
+///                        icon in a window or by calling `nk_window_close`. Only closed
+///                        windows get removed at the end of the frame while hidden windows
+///                        remain.
+/// - 2016/08/08 (1.06.0) - Added `nk_edit_string_zero_terminated` as a second option to
+///                        `nk_edit_string` which takes, edits and outputs a '\0' terminated string.
+/// - 2016/08/08 (1.05.4)- Fixed scrollbar auto hiding behavior
+/// - 2016/08/08 (1.05.3)- Fixed wrong panel padding selection in `nk_layout_widget_space`
+/// - 2016/08/07 (1.05.2)- Fixed old bug in dynamic immediate mode layout API, calculating
+///                        wrong item spacing and panel width.
+///- 2016/08/07 (1.05.1)- Hopefully finally fixed combobox popup drawing bug
+///- 2016/08/07 (1.05.0) - Split varargs away from NK_INCLUDE_STANDARD_IO into own
+///                        define NK_INCLUDE_STANDARD_VARARGS to allow more fine
+///                        grained controlled over library includes.
+/// - 2016/08/06 (1.04.5)- Changed memset calls to NK_MEMSET
+/// - 2016/08/04 (1.04.4)- Fixed fast window scaling behavior
+/// - 2016/08/04 (1.04.3)- Fixed window scaling, movement bug which appears if you
+///                        move/scale a window and another window is behind it.
+///                        If you are fast enough then the window behind gets activated
+///                        and the operation is blocked. I now require activating
+///                        by hovering only if mouse is not pressed.
+/// - 2016/08/04 (1.04.2)- Fixed changing fonts
+/// - 2016/08/03 (1.04.1)- Fixed `NK_WINDOW_BACKGROUND` behavior
+/// - 2016/08/03 (1.04.0) - Added color parameter to `nk_draw_image`
+/// - 2016/08/03 (1.04.0) - Added additional window padding style attributes for
+///                        sub windows (combo, menu, ...)
+/// - 2016/08/03 (1.04.0) - Added functions to show/hide software cursor
+/// - 2016/08/03 (1.04.0) - Added `NK_WINDOW_BACKGROUND` flag to force a window
+///                        to be always in the background of the screen
+/// - 2016/08/03 (1.03.2)- Removed invalid assert macro for NK_RGB color picker
+/// - 2016/08/01 (1.03.1)- Added helper macros into header include guard
+/// - 2016/07/29 (1.03.0) - Moved the window/table pool into the header part to
+///                        simplify memory management by removing the need to
+///                        allocate the pool.
+/// - 2016/07/29 (1.02.0) - Added auto scrollbar hiding window flag which if enabled
+///                        will hide the window scrollbar after NK_SCROLLBAR_HIDING_TIMEOUT
+///                        seconds without window interaction. To make it work
+///                        you have to also set a delta time inside the `nk_context`.
+/// - 2016/07/25 (1.01.1) - Fixed small panel and panel border drawing bugs
+/// - 2016/07/15 (1.01.0) - Added software cursor to `nk_style` and `nk_context`
+/// - 2016/07/15 (1.01.0) - Added const correctness to `nk_buffer_push' data argument
+/// - 2016/07/15 (1.01.0) - Removed internal font baking API and simplified
+///                        font atlas memory management by converting pointer
+///                        arrays for fonts and font configurations to lists.
+/// - 2016/07/15 (1.00.0) - Changed button API to use context dependend button
+///                        behavior instead of passing it for every function call.

+/* stb_image_write - v1.02 - public domain - http://nothings.org/stb/stb_image_write.h
+   writes out PNG/BMP/TGA images to C stdio - Sean Barrett 2010-2015
+                                     no warranty implied; use at your own risk
+
+   Before #including,
+
+       #define STB_IMAGE_WRITE_IMPLEMENTATION
+
+   in the file that you want to have the implementation.
+
+   Will probably not work correctly with strict-aliasing optimizations.
+
+ABOUT:
+
+   This header file is a library for writing images to C stdio. It could be
+   adapted to write to memory or a general streaming interface; let me know.
+
+   The PNG output is not optimal; it is 20-50% larger than the file
+   written by a decent optimizing implementation. This library is designed
+   for source code compactness and simplicity, not optimal image file size
+   or run-time performance.
+
+BUILDING:
+
+   You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h.
+   You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace
+   malloc,realloc,free.
+   You can define STBIW_MEMMOVE() to replace memmove()
+
+USAGE:
+
+   There are four functions, one for each image file format:
+
+     int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes);
+     int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data);
+     int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data);
+     int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data);
+
+   There are also four equivalent functions that use an arbitrary write function. You are
+   expected to open/close your file-equivalent before and after calling these:
+
+     int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data, int stride_in_bytes);
+     int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data);
+     int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data);
+     int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data);
+
+   where the callback is:
+      void stbi_write_func(void *context, void *data, int size);
+
+   You can define STBI_WRITE_NO_STDIO to disable the file variant of these
+   functions, so the library will not use stdio.h at all. However, this will
+   also disable HDR writing, because it requires stdio for formatted output.
+
+   Each function returns 0 on failure and non-0 on success.
+
+   The functions create an image file defined by the parameters. The image
+   is a rectangle of pixels stored from left-to-right, top-to-bottom.
+   Each pixel contains 'comp' channels of data stored interleaved with 8-bits
+   per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is
+   monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall.
+   The *data pointer points to the first byte of the top-left-most pixel.
+   For PNG, "stride_in_bytes" is the distance in bytes from the first byte of
+   a row of pixels to the first byte of the next row of pixels.
+
+   PNG creates output files with the same number of components as the input.
+   The BMP format expands Y to RGB in the file format and does not
+   output alpha.
+
+   PNG supports writing rectangles of data even when the bytes storing rows of
+   data are not consecutive in memory (e.g. sub-rectangles of a larger image),
+   by supplying the stride between the beginning of adjacent rows. The other
+   formats do not. (Thus you cannot write a native-format BMP through the BMP
+   writer, both because it is in BGR order and because it may have padding
+   at the end of the line.)
+
+   HDR expects linear float data. Since the format is always 32-bit rgb(e)
+   data, alpha (if provided) is discarded, and for monochrome data it is
+   replicated across all three channels.
+
+   TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed
+   data, set the global variable 'stbi_write_tga_with_rle' to 0.

+*
+* @section intro_sec Introduction
+* TinyCThread is a minimal, portable implementation of basic threading
+* classes for C.
+*
+* They closely mimic the functionality and naming of the C11 standard, and
+* should be easily replaceable with the corresponding standard variants.
+*
+* @section port_sec Portability
+* The Win32 variant uses the native Win32 API for implementing the thread
+* classes, while for other systems, the POSIX threads API (pthread) is used.
+*
+* @section misc_sec Miscellaneous
+* The following special keywords are available: #_Thread_local.
+*
+* For more detailed information, browse the different sections of this
+* documentation. A good place to start is:
+* tinycthread.h.

+## Asking a question
+
+Questions about how to use GLFW should be asked either in the [support
+section](https://discourse.glfw.org/c/support) of the forum, under the [Stack
+Overflow tag](https://stackoverflow.com/questions/tagged/glfw) or [Game
+Development tag](https://gamedev.stackexchange.com/questions/tagged/glfw) on
+Stack Exchange or in the IRC channel `#glfw` on
+[Freenode](http://freenode.net/).
+
+Questions about the design or implementation of GLFW or about future plans
+should be asked in the [dev section](https://discourse.glfw.org/c/dev) of the
+forum or in the IRC channel.  Please don't open a GitHub issue to discuss design
+questions without first checking with a maintainer.
+
+
+## Reporting a bug
+
+If GLFW is behaving unexpectedly at run-time, start by setting an [error
+callback](https://www.glfw.org/docs/latest/intro_guide.html#error_handling).
+GLFW will often tell you the cause of an error via this callback.  If it
+doesn't, that might be a separate bug.
+
+If GLFW is crashing or triggering asserts, make sure that all your object
+handles and other pointers are valid.
+
+For bugs where it makes sense, a short, self contained example is absolutely
+invaluable.  Just put it inline in the body text.  Note that if the bug is
+reproducible with one of the test programs that come with GLFW, just mention
+that instead.
+
+__Don't worry about adding too much information__.  Unimportant information can
+be abbreviated or removed later, but missing information can stall bug fixing,
+especially when your schedule doesn't align with that of the maintainer.
+
+__Please provide text as text, not as images__.  This includes code, error
+messages and any other text.  Text in images cannot be found by other users
+searching for the same problem and may have to be re-typed by maintainers when
+debugging.
+
+You don't need to manually indent your code or other text to quote it with
+GitHub Markdown; just surround it with triple backticks:
+
+    ```
+    Some quoted text.
+    ```
+
+You can also add syntax highlighting by appending the common file extension:
+
+    ```c

+it already has everything, give it a :+1:.
+
+
+### Reporting a compile or link bug
+
+__Note:__ GLFW needs many system APIs to do its job, which on some platforms
+means linking to many system libraries.  If you are using GLFW as a static
+library, that means your application needs to link to these in addition to GLFW.
+
+__Note:__ Check the [Compiling
+GLFW](https://www.glfw.org/docs/latest/compile.html) guide and or [Building
+applications](https://www.glfw.org/docs/latest/build.html) guide for before
+opening an issue of this kind.  Most issues are caused by a missing package or
+linker flag.
+
+Always include the __operating system name and version__ (e.g. `Windows
+7 64-bit` or `Ubuntu 15.10`) and the __compiler name and version__ (e.g. `Visual
+C++ 2015 Update 2`).  If you are using an official release of GLFW,
+include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the
+__GLFW commit ID__ (e.g.  `3795d78b14ef06008889cc422a1fb8d642597751`) from Git.
+
+Please also include the __complete build log__ from your compiler and linker,
+even if it's long.  It can always be shortened later, if necessary.

+### Reporting a segfault or other crash bug
+
+Always include the __operating system name and version__ (e.g. `Windows
+7 64-bit` or `Ubuntu 15.10`).  If you are using an official release of GLFW,
+include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the
+__GLFW commit ID__ (e.g.  `3795d78b14ef06008889cc422a1fb8d642597751`) from Git.
+
+Please also include any __error messages__ provided to your application via the
+[error
+callback](https://www.glfw.org/docs/latest/intro_guide.html#error_handling) and
+the __full call stack__ of the crash, or if the crash does not occur in debug
+mode, mention that instead.

+
+### Reporting a context creation bug
+
+__Note:__ Windows ships with graphics drivers that do not support OpenGL.  If
+GLFW says that your machine lacks support for OpenGL, it very likely does.
+Install drivers from the computer manufacturer or graphics card manufacturer
+([Nvidia](https://www.geforce.com/drivers),
+[AMD](https://www.amd.com/en/support),
+[Intel](https://www-ssl.intel.com/content/www/us/en/support/detect.html)) to
+fix this.
+
+__Note:__ AMD only supports OpenGL ES on Windows via EGL.  See the
+[GLFW\_CONTEXT\_CREATION\_API](https://www.glfw.org/docs/latest/window_guide.html#window_hints_ctx)
+hint for how to select EGL.
+
+Please verify that context creation also fails with the `glfwinfo` tool before
+reporting it as a bug.  This tool is included in the GLFW source tree as
+`tests/glfwinfo.c` and is built along with the library.  It has switches for all
+GLFW context and framebuffer hints.  Run `glfwinfo -h` for a complete list.
+
+Always include the __operating system name and version__ (e.g. `Windows
+7 64-bit` or `Ubuntu 15.10`).  If you are using an official release of GLFW,
+include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the
+__GLFW commit ID__ (e.g.  `3795d78b14ef06008889cc422a1fb8d642597751`) from Git.
+
+If you are running your program in a virtual machine, please mention this and
+include the __VM name and version__ (e.g. `VirtualBox 5.1`).
+
+Please also include the __GLFW version string__ (`3.2.0 X11 EGL clock_gettime
+/dev/js`), as described
+[here](https://www.glfw.org/docs/latest/intro.html#intro_version_string), the
+__GPU model and driver version__ (e.g. `GeForce GTX660 with 352.79`), and the
+__output of `glfwinfo`__ (with switches matching any hints you set in your
+code) when reporting this kind of bug.  If this tool doesn't run on the machine,
+mention that instead.

+
+### Reporting a monitor or video mode bug
+
+__Note:__ On headless systems on some platforms, no monitors are reported.  This
+causes glfwGetPrimaryMonitor to return `NULL`, which not all applications are
+prepared for.
+
+__Note:__ Some third-party tools report more video modes than are approved of
+by the OS.  For safety and compatibility, GLFW only reports video modes the OS
+wants programs to use.  This is not a bug.
+
+The `monitors` tool is included in the GLFW source tree as `tests/monitors.c`
+and is built along with the library.  It lists all information GLFW provides
+about monitors it detects.
+
+Always include the __operating system name and version__ (e.g. `Windows
+7 64-bit` or `Ubuntu 15.10`).  If you are using an official release of GLFW,
+include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the
+__GLFW commit ID__ (e.g.  `3795d78b14ef06008889cc422a1fb8d642597751`) from Git.
+
+If you are running your program in a virtual machine, please mention this and
+include the __VM name and version__ (e.g. `VirtualBox 5.1`).
+
+Please also include any __error messages__ provided to your application via the
+[error
+callback](https://www.glfw.org/docs/latest/intro_guide.html#error_handling) and
+the __output of `monitors`__ when reporting this kind of bug.  If this tool
+doesn't run on the machine, mention this instead.

+
+### Reporting a window, input or event bug
+
+__Note:__ The exact ordering of related window events will sometimes differ.
+
+__Note:__ Window moving and resizing (by the user) will block the main thread on
+some platforms.  This is not a bug.  Set a [refresh
+callback](https://www.glfw.org/docs/latest/window.html#window_refresh) if you
+want to keep the window contents updated during a move or size operation.
+
+The `events` tool is included in the GLFW source tree as `tests/events.c` and is
+built along with the library.  It prints all information provided to every
+callback supported by GLFW as events occur.  Each event is listed with the time
+and a unique number to make discussions about event logs easier.  The tool has
+command-line options for creating multiple windows and full screen windows.
+
+Always include the __operating system name and version__ (e.g. `Windows
+7 64-bit` or `Ubuntu 15.10`).  If you are using an official release of GLFW,
+include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the
+__GLFW commit ID__ (e.g.  `3795d78b14ef06008889cc422a1fb8d642597751`) from Git.

+
+__X11:__ If possible, please include what desktop environment (e.g. GNOME,
+Unity, KDE) and/or window manager (e.g. Openbox, dwm, Window Maker) you are

+### Reporting a documentation bug
+
+If you found a bug in the documentation, including this file, then it's fine to
+just link to that web page or mention that source file.  You don't need to match
+the source to the output or vice versa.
+
+
+### Reporting a website bug
+
+If the bug is in the documentation (anything under `/docs/`) then please see the
+section above.  Bugs in the rest of the site are reported to the [website
+source repository](https://github.com/glfw/website/issues).
+
+
+## Requesting a feature
+
+Please explain why you need the feature and how you intend to use it.  If you
+have a specific API design in mind, please add that as well.  If you have or are
+planning to write code for the feature, see the section below.
+
+If there already is a request for the feature you need, add your specific use
+case unless it is already mentioned.  If it is, give it a :+1:.
+
+
+## Contributing a bug fix
+
+__Note:__ You must have all necessary [intellectual
+property rights](https://en.wikipedia.org/wiki/Intellectual_property) to any
+code you contribute.  If you did not write the code yourself, you must explain
+where it came from and under what license you received it.  Even code using the
+same license as GLFW may not be copied without attribution.
+
+__There is no preferred patch size__.  A one character fix is just as welcome as
+a thousand line one, if that is the appropriate size for the fix.
+
+In addition to the code, a complete bug fix includes:
+
+- Change log entry in `README.md`, describing the incorrect behavior
+- Credits entries for all authors of the bug fix
+
+Bug fixes will not be rejected because they don't include all the above parts,
+but please keep in mind that maintainer time is finite and that there are many
+other bugs and features to work on.
+
+If the patch fixes a bug introduced after the last release, it should not get
+a change log entry.
+
+If you haven't already, read the excellent article [How to Write a Git Commit
+Message](https://chris.beams.io/posts/git-commit/).

+## Contributing a feature
+
+__Note:__ You must have all necessary rights to any code you contribute.  If you
+did not write the code yourself, you must explain where it came from and under
+what license.  Even code using the same license as GLFW may not be copied
+without attribution.
+
+__Note:__ If you haven't already implemented the feature, check first if there
+already is an open issue for it and if it's already being developed in an
+[experimental branch](https://github.com/glfw/glfw/branches/all).
+
+__There is no preferred patch size__.  A one character change is just as welcome
+as one adding a thousand line one, if that is the appropriate size for the
+feature.
+
+In addition to the code, a complete feature includes:
+
+- Change log entry in `README.md`, listing all new symbols
+- News page entry, briefly describing the feature
+- Guide documentation, with minimal examples, in the relevant guide
+- Reference documentation, with all applicable tags
+- Cross-references and mentions in appropriate places
+- Credits entries for all authors of the feature
+
+If the feature requires platform-specific code, at minimum stubs must be added
+for the new platform function to all supported and experimental platforms.
+
+If it adds a new callback, support for it must be added to `tests/event.c`.
+
+If it adds a new monitor property, support for it must be added to
+`tests/monitor.c`.
+
+If it adds a new OpenGL, OpenGL ES or Vulkan option or extension, support
+for it must be added to `tests/glfwinfo.c` and the behavior of the library when
+the extension is missing documented in `docs/compat.dox`.
+
+If you haven't already, read the excellent article [How to Write a Git Commit
+Message](https://chris.beams.io/posts/git-commit/).
+
+Features will not be rejected because they don't include all the above parts,
+but please keep in mind that maintainer time is finite and that there are many
+other features and bugs to work on.
+
+Please also keep in mind that any part of the public API that has been included
+in a release cannot be changed until the next _major_ version.  Features can be
+added and existing parts can sometimes be overloaded (in the general sense of
+doing more things, not in the C++ sense), but code written to the API of one
+minor release should both compile and run on subsequent minor releases.

+
+@page build_guide Building applications
+
+@tableofcontents
+
+This is about compiling and linking applications that use GLFW.  For information on
+how to write such applications, start with the
+[introductory tutorial](@ref quick_guide).  For information on how to compile
+the GLFW library itself, see @ref compile_guide.
+
+This is not a tutorial on compilation or linking.  It assumes basic
+understanding of how to compile and link a C program as well as how to use the
+specific compiler of your chosen development environment.  The compilation
+and linking process should be explained in your C programming material and in
+the documentation for your development environment.
+
+
+@section build_include Including the GLFW header file
+
+You should include the GLFW header in the source files where you use OpenGL or
+GLFW.
+
+@code
+#include <GLFW/glfw3.h>
+@endcode
+
+This header declares the GLFW API and by default also includes the OpenGL header
+from your development environment.  See below for how to control this.
+
+The GLFW header also defines any platform-specific macros needed by your OpenGL
+header, so it can be included without needing any window system headers.
+
+For example, under Windows you are normally required to include `windows.h`
+before the OpenGL header, which would bring in the whole Win32 API.  The GLFW
+header duplicates the small number of macros needed.
+
+It does this only when needed, so if `windows.h` _is_ included, the GLFW header
+does not try to redefine those symbols.  The reverse is not true, i.e.
+`windows.h` cannot cope if any of its symbols have already been defined.
+
+In other words:
+
+ - Do _not_ include the OpenGL headers yourself, as GLFW does this for you
+ - Do _not_ include `windows.h` or other platform-specific headers unless you
+   plan on using those APIs directly
+ - If you _do_ need to include such headers, do it _before_ including
+   the GLFW header and it will handle this
+
+If you are using an OpenGL extension loading library such as
+[glad](https://github.com/Dav1dde/glad), the extension loader header should
+be included _before_ the GLFW one.
+
+@code
+#include <glad/gl.h>
+#include <GLFW/glfw3.h>
+@endcode
+
+Alternatively the @ref GLFW_INCLUDE_NONE macro (described below) can be used to
+prevent the GLFW header from including the OpenGL header.
+
+@code
+#define GLFW_INCLUDE_NONE
+#include <GLFW/glfw3.h>
+#include <glad/gl.h>
+@endcode
+
+
+@subsection build_macros GLFW header option macros
+
+These macros may be defined before the inclusion of the GLFW header and affect
+its behavior.
+
+@anchor GLFW_DLL
+__GLFW_DLL__ is required on Windows when using the GLFW DLL, to tell the
+compiler that the GLFW functions are defined in a DLL.
+
+The following macros control which OpenGL or OpenGL ES API header is included.
+Only one of these may be defined at a time.
+
+@note GLFW does not provide any of the API headers mentioned below.  They are
+provided by your development environment or your OpenGL, OpenGL ES or Vulkan
+SDK, and most of them can be downloaded from the
+[Khronos Registry](https://www.khronos.org/registry/).
+
+@anchor GLFW_INCLUDE_GLCOREARB
+__GLFW_INCLUDE_GLCOREARB__ makes the GLFW header include the modern
+`GL/glcorearb.h` header (`OpenGL/gl3.h` on macOS) instead of the regular OpenGL
+header.
+
+@anchor GLFW_INCLUDE_ES1
+__GLFW_INCLUDE_ES1__ makes the GLFW header include the OpenGL ES 1.x `GLES/gl.h`
+header instead of the regular OpenGL header.
+
+@anchor GLFW_INCLUDE_ES2
+__GLFW_INCLUDE_ES2__ makes the GLFW header include the OpenGL ES 2.0
+`GLES2/gl2.h` header instead of the regular OpenGL header.
+
+@anchor GLFW_INCLUDE_ES3
+__GLFW_INCLUDE_ES3__ makes the GLFW header include the OpenGL ES 3.0
+`GLES3/gl3.h` header instead of the regular OpenGL header.
+
+@anchor GLFW_INCLUDE_ES31
+__GLFW_INCLUDE_ES31__ makes the GLFW header include the OpenGL ES 3.1
+`GLES3/gl31.h` header instead of the regular OpenGL header.
+
+@anchor GLFW_INCLUDE_ES32
+__GLFW_INCLUDE_ES31__ makes the GLFW header include the OpenGL ES 3.2
+`GLES3/gl32.h` header instead of the regular OpenGL header.
+
+@anchor GLFW_INCLUDE_NONE
+__GLFW_INCLUDE_NONE__ makes the GLFW header not include any OpenGL or OpenGL ES
+API header.  This is useful in combination with an extension loading library.
+
+If none of the above inclusion macros are defined, the standard OpenGL `GL/gl.h`
+header (`OpenGL/gl.h` on macOS) is included.
+
+The following macros control the inclusion of additional API headers.  Any
+number of these may be defined simultaneously, and/or together with one of the
+above macros.
+
+@anchor GLFW_INCLUDE_VULKAN
+__GLFW_INCLUDE_VULKAN__ makes the GLFW header include the Vulkan
+`vulkan/vulkan.h` header in addition to any selected OpenGL or OpenGL ES header.
+
+@anchor GLFW_INCLUDE_GLEXT
+__GLFW_INCLUDE_GLEXT__ makes the GLFW header include the appropriate extension
+header for the OpenGL or OpenGL ES header selected above after and in addition
+to that header.
+
+@anchor GLFW_INCLUDE_GLU
+__GLFW_INCLUDE_GLU__ makes the header include the GLU header in addition to the
+header selected above.  This should only be used with the standard OpenGL header
+and only for compatibility with legacy code.  GLU has been deprecated and should
+not be used in new code.
+
+@note None of these macros may be defined during the compilation of GLFW itself.
+If your build includes GLFW and you define any these in your build files, make
+sure they are not applied to the GLFW sources.
+
+
+@section build_link Link with the right libraries
+
+GLFW is essentially a wrapper of various platform-specific APIs and therefore
+needs to link against many different system libraries.  If you are using GLFW as
+a shared library / dynamic library / DLL then it takes care of these links.
+However, if you are using GLFW as a static library then your executable will
+need to link against these libraries.
+
+On Windows and macOS, the list of system libraries is static and can be
+hard-coded into your build environment.  See the section for your development
+environment below.  On Linux and other Unix-like operating systems, the list
+varies but can be retrieved in various ways as described below.
+
+A good general introduction to linking is
+[Beginner's Guide to Linkers](https://www.lurklurk.org/linkers/linkers.html) by
+David Drysdale.
+
+
+@subsection build_link_win32 With MinGW or Visual C++ on Windows
+
+The static version of the GLFW library is named `glfw3`.  When using this
+version, it is also necessary to link with some libraries that GLFW uses.
+
+When using MinGW to link an application with the static version of GLFW, you
+must also explicitly link with `gdi32`. Other toolchains including MinGW-w64
+include it in the set of default libraries along with other dependencies like
+`user32` and `kernel32`.
+
+The link library for the GLFW DLL is named `glfw3dll`.  When compiling an
+application that uses the DLL version of GLFW, you need to define the @ref
+GLFW_DLL macro _before_ any inclusion of the GLFW header.  This can be done
+either with a compiler switch or by defining it in your source code.
+
+
+@subsection build_link_cmake_source With CMake and GLFW source
+
+This section is about using CMake to compile and link GLFW along with your
+application.  If you want to use an installed binary instead, see @ref
+build_link_cmake_package.
+
+With a few changes to your `CMakeLists.txt` you can have the GLFW source tree
+built along with your application.
+
+When including GLFW as part of your build, you probably don't want to build the
+GLFW tests, examples and documentation.  To disable these, set the corresponding
+cache variables before adding the GLFW source tree.
+
+@code
+set(GLFW_BUILD_DOCS OFF CACHE BOOL "" FORCE)
+set(GLFW_BUILD_TESTS OFF CACHE BOOL "" FORCE)
+set(GLFW_BUILD_EXAMPLES OFF CACHE BOOL "" FORCE)
+@endcode
+
+Add the root directory of the GLFW source tree to your project.  This will add
+the `glfw` target to your project.
+
+@code{.cmake}
+add_subdirectory(path/to/glfw)
+@endcode
+
+Once GLFW has been added, link your application against the `glfw` target.
+This adds the GLFW library and its link-time dependencies as it is currently
+configured, the include directory for the GLFW header and, when applicable, the
+@ref GLFW_DLL macro.
+
+@code{.cmake}
+target_link_libraries(myapp glfw)
+@endcode
+
+Note that the `glfw` target does not depend on OpenGL, as GLFW loads any OpenGL,
+OpenGL ES or Vulkan libraries it needs at runtime.  If your application calls
+OpenGL directly, instead of using a modern
+[extension loader library](@ref context_glext_auto), use the OpenGL CMake
+package.
+
+@code{.cmake}
+find_package(OpenGL REQUIRED)
+@endcode
+
+If OpenGL is found, the `OpenGL::GL` target is added to your project, containing
+library and include directory paths.  Link against this like above.
+
+@code{.cmake}
+target_link_libraries(myapp OpenGL::GL)
+@endcode
+
+
+@subsection build_link_cmake_package With CMake and installed GLFW binaries
+
+This section is about using CMake to link GLFW after it has been built and
+installed.  If you want to build it along with your application instead, see
+@ref build_link_cmake_source.
+
+With a few changes to your `CMakeLists.txt` you can locate the package and
+target files generated when GLFW is installed.
+
+@code{.cmake}
+find_package(glfw3 3.3 REQUIRED)
+@endcode
+
+Once GLFW has been added to the project, link against it with the `glfw` target.
+This adds the GLFW library and its link-time dependencies, the include directory
+for the GLFW header and, when applicable, the @ref GLFW_DLL macro.
+
+@code{.cmake}
+target_link_libraries(myapp glfw)
+@endcode
+
+Note that the `glfw` target does not depend on OpenGL, as GLFW loads any OpenGL,
+OpenGL ES or Vulkan libraries it needs at runtime.  If your application calls
+OpenGL directly, instead of using a modern
+[extension loader library](@ref context_glext_auto), use the OpenGL CMake
+package.
+
+@code{.cmake}
+find_package(OpenGL REQUIRED)
+@endcode
+
+If OpenGL is found, the `OpenGL::GL` target is added to your project, containing
+library and include directory paths.  Link against this like above.
+
+@code{.cmake}
+target_link_libraries(myapp OpenGL::GL)
+@endcode
+
+
+@subsection build_link_pkgconfig With makefiles and pkg-config on Unix
+
+GLFW supports [pkg-config](https://www.freedesktop.org/wiki/Software/pkg-config/),
+and the `glfw3.pc` pkg-config file is generated when the GLFW library is built
+and is installed along with it.  A pkg-config file describes all necessary
+compile-time and link-time flags and dependencies needed to use a library.  When
+they are updated or if they differ between systems, you will get the correct
+ones automatically.
+
+A typical compile and link command-line when using the static version of the
+GLFW library may look like this:
+
+@code{.sh}
+cc $(pkg-config --cflags glfw3) -o myprog myprog.c $(pkg-config --static --libs glfw3)
+@endcode
+
+If you are using the shared version of the GLFW library, omit the `--static`
+flag.
+
+@code{.sh}
+cc $(pkg-config --cflags glfw3) -o myprog myprog.c $(pkg-config --libs glfw3)
+@endcode
+
+You can also use the `glfw3.pc` file without installing it first, by using the
+`PKG_CONFIG_PATH` environment variable.
+
+@code{.sh}
+env PKG_CONFIG_PATH=path/to/glfw/src cc $(pkg-config --cflags glfw3) -o myprog myprog.c $(pkg-config --libs glfw3)
+@endcode
+
+The dependencies do not include OpenGL, as GLFW loads any OpenGL, OpenGL ES or
+Vulkan libraries it needs at runtime.  If your application calls OpenGL
+directly, instead of using a modern
+[extension loader library](@ref context_glext_auto), you should add the `gl`
+pkg-config package.
+
+@code{.sh}
+cc $(pkg-config --cflags glfw3 gl) -o myprog myprog.c $(pkg-config --libs glfw3 gl)
+@endcode
+
+
+@subsection build_link_xcode With Xcode on macOS
+
+If you are using the dynamic library version of GLFW, add it to the project
+dependencies.
+
+If you are using the static library version of GLFW, add it and the Cocoa,
+OpenGL and IOKit frameworks to the project as dependencies.  They can all be
+found in `/System/Library/Frameworks`.
+
+
+@subsection build_link_osx With command-line on macOS
+
+It is recommended that you use [pkg-config](@ref build_link_pkgconfig) when
+building from the command line on macOS.  That way you will get any new
+dependencies added automatically.  If you still wish to build manually, you need
+to add the required frameworks and libraries to your command-line yourself using
+the `-l` and `-framework` switches.
+
+If you are using the dynamic GLFW library, which is named `libglfw.3.dylib`, do:
+
+@code{.sh}
+cc -o myprog myprog.c -lglfw -framework Cocoa -framework OpenGL -framework IOKit
+@endcode
+
+If you are using the static library, named `libglfw3.a`, substitute `-lglfw3`
+for `-lglfw`.
+
+Note that you do not add the `.framework` extension to a framework when linking
+against it from the command-line.
+
+@note Your machine may have `libGL.*.dylib` style OpenGL library, but that is
+for the X Window System and will not work with the macOS native version of GLFW.

+
+@page compat_guide Standards conformance
+
+@tableofcontents
+
+This guide describes the various API extensions used by this version of GLFW.
+It lists what are essentially implementation details, but which are nonetheless
+vital knowledge for developers intending to deploy their applications on a wide
+range of machines.
+
+The information in this guide is not a part of GLFW API, but merely
+preconditions for some parts of the library to function on a given machine.  Any
+part of this information may change in future versions of GLFW and that will not
+be considered a breaking API change.
+
+
+@section compat_x11 X11 extensions, protocols and IPC standards
+
+As GLFW uses Xlib directly, without any intervening toolkit
+library, it has sole responsibility for interacting well with the many and
+varied window managers in use on Unix-like systems.  In order for applications
+and window managers to work well together, a number of standards and
+conventions have been developed that regulate behavior outside the scope of the
+X11 API; most importantly the
+[Inter-Client Communication Conventions Manual](https://www.tronche.com/gui/x/icccm/)
+(ICCCM) and
+[Extended Window Manager Hints](https://standards.freedesktop.org/wm-spec/wm-spec-latest.html)
+(EWMH) standards.
+
+GLFW uses the `_MOTIF_WM_HINTS` window property to support borderless windows.
+If the running window manager does not support this property, the
+`GLFW_DECORATED` hint will have no effect.
+
+GLFW uses the ICCCM `WM_DELETE_WINDOW` protocol to intercept the user
+attempting to close the GLFW window.  If the running window manager does not
+support this protocol, the close callback will never be called.
+
+GLFW uses the EWMH `_NET_WM_PING` protocol, allowing the window manager notify
+the user when the application has stopped responding, i.e. when it has ceased to
+process events.  If the running window manager does not support this protocol,
+the user will not be notified if the application locks up.
+
+GLFW uses the EWMH `_NET_WM_STATE_FULLSCREEN` window state to tell the window
+manager to make the GLFW window full screen.  If the running window manager does
+not support this state, full screen windows may not work properly.  GLFW has
+a fallback code path in case this state is unavailable, but every window manager
+behaves slightly differently in this regard.
+
+GLFW uses the EWMH `_NET_WM_BYPASS_COMPOSITOR` window property to tell a
+compositing window manager to un-redirect full screen GLFW windows.  If the
+running window manager uses compositing but does not support this property then
+additional copying may be performed for each buffer swap of full screen windows.
+
+GLFW uses the
+[clipboard manager protocol](https://www.freedesktop.org/wiki/ClipboardManager/)
+to push a clipboard string (i.e. selection) owned by a GLFW window about to be
+destroyed to the clipboard manager.  If there is no running clipboard manager,
+the clipboard string will be unavailable once the window has been destroyed.
+
+GLFW uses the
+[X drag-and-drop protocol](https://www.freedesktop.org/wiki/Specifications/XDND/)
+to provide file drop events.  If the application originating the drag does not
+support this protocol, drag and drop will not work.
+
+GLFW uses the XRandR 1.3 extension to provide multi-monitor support.  If the
+running X server does not support this version of this extension, multi-monitor
+support will not function and only a single, desktop-spanning monitor will be
+reported.
+
+GLFW uses the XRandR 1.3 and Xf86vidmode extensions to provide gamma ramp
+support.  If the running X server does not support either or both of these
+extensions, gamma ramp support will not function.
+
+GLFW uses the Xkb extension and detectable auto-repeat to provide keyboard
+input.  If the running X server does not support this extension, a non-Xkb
+fallback path is used.
+
+GLFW uses the XInput2 extension to provide raw, non-accelerated mouse motion
+when the cursor is disabled.  If the running X server does not support this
+extension, regular accelerated mouse motion will be used.
+
+GLFW uses both the XRender extension and the compositing manager to support
+transparent window framebuffers.  If the running X server does not support this
+extension or there is no running compositing manager, the
+`GLFW_TRANSPARENT_FRAMEBUFFER` framebuffer hint will have no effect.
+
+
+@section compat_wayland Wayland protocols and IPC standards
+
+As GLFW uses libwayland directly, without any intervening toolkit library, it
+has sole responsibility for interacting well with every compositor in use on
+Unix-like systems.  Most of the features are provided by the core protocol,
+while cursor support is provided by the libwayland-cursor helper library, EGL
+integration by libwayland-egl, and keyboard handling by
+[libxkbcommon](https://xkbcommon.org/).  In addition, GLFW uses some protocols
+from wayland-protocols to provide additional features if the compositor
+supports them.
+
+GLFW uses xkbcommon 0.5.0 to provide compose key support.  When it has been
+built against an older xkbcommon, the compose key will be disabled even if it
+has been configured in the compositor.
+
+GLFW uses the [xdg-shell
+protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/stable/xdg-shell/xdg-shell.xml)
+to provide better window management.  This protocol is part of
+wayland-protocols 1.12, and mandatory at build time.  If the running compositor
+does not support this protocol, the older [wl_shell
+interface](https://cgit.freedesktop.org/wayland/wayland/tree/protocol/wayland.xml#n972)
+will be used instead.  This will result in a worse integration with the
+desktop, especially on tiling compositors.
+
+GLFW uses the [relative pointer
+protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/relative-pointer/relative-pointer-unstable-v1.xml)
+alongside the [pointer constraints
+protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/pointer-constraints/pointer-constraints-unstable-v1.xml)
+to implement disabled cursor.  These two protocols are part of
+wayland-protocols 1.1, and mandatory at build time.  If the running compositor
+does not support both of these protocols, disabling the cursor will have no
+effect.
+
+GLFW uses the [idle inhibit
+protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/idle-inhibit/idle-inhibit-unstable-v1.xml)
+to prohibit the screensaver from starting.  This protocol is part of
+wayland-protocols 1.6, and mandatory at build time.  If the running compositor
+does not support this protocol, the screensaver may start even for full screen
+windows.
+
+GLFW uses the [xdg-decoration
+protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/xdg-decoration/xdg-decoration-unstable-v1.xml)
+to request decorations to be drawn around its windows.  This protocol is part
+of wayland-protocols 1.15, and mandatory at build time.  If the running
+compositor does not support this protocol, a very simple frame will be drawn by
+GLFW itself, using the [viewporter
+protocol](https://cgit.freedesktop.org/wayland/wayland-protocols/tree/stable/viewporter/viewporter.xml)
+alongside
+[subsurfaces](https://cgit.freedesktop.org/wayland/wayland/tree/protocol/wayland.xml#n2598).
+This protocol is part of wayland-protocols 1.4, and mandatory at build time.
+If the running compositor does not support this protocol either, no decorations
+will be drawn around windows.
+
+
+@section compat_glx GLX extensions
+
+The GLX API is the default API used to create OpenGL contexts on Unix-like
+systems using the X Window System.
+
+GLFW uses the GLX 1.3 `GLXFBConfig` functions to enumerate and select framebuffer pixel
+formats.  If GLX 1.3 is not supported, @ref glfwInit will fail.
+
+GLFW uses the `GLX_MESA_swap_control,` `GLX_EXT_swap_control` and
+`GLX_SGI_swap_control` extensions to provide vertical retrace synchronization
+(or _vsync_), in that order of preference.  Where none of these extension are
+available, calling @ref glfwSwapInterval will have no effect.
+
+GLFW uses the `GLX_ARB_multisample` extension to create contexts with
+multisampling anti-aliasing.  Where this extension is unavailable, the
+`GLFW_SAMPLES` hint will have no effect.
+
+GLFW uses the `GLX_ARB_create_context` extension when available, even when
+creating OpenGL contexts of version 2.1 and below.  Where this extension is
+unavailable, the `GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR`
+hints will only be partially supported, the `GLFW_OPENGL_DEBUG_CONTEXT` hint
+will have no effect, and setting the `GLFW_OPENGL_PROFILE` or
+`GLFW_OPENGL_FORWARD_COMPAT` hints to `GLFW_TRUE` will cause @ref
+glfwCreateWindow to fail.
+
+GLFW uses the `GLX_ARB_create_context_profile` extension to provide support for
+context profiles.  Where this extension is unavailable, setting the
+`GLFW_OPENGL_PROFILE` hint to anything but `GLFW_OPENGL_ANY_PROFILE`, or setting
+`GLFW_CLIENT_API` to anything but `GLFW_OPENGL_API` or `GLFW_NO_API` will cause
+@ref glfwCreateWindow to fail.
+
+GLFW uses the `GLX_ARB_context_flush_control` extension to provide control over
+whether a context is flushed when it is released (made non-current).  Where this
+extension is unavailable, the `GLFW_CONTEXT_RELEASE_BEHAVIOR` hint will have no
+effect and the context will always be flushed when released.
+
+GLFW uses the `GLX_ARB_framebuffer_sRGB` and `GLX_EXT_framebuffer_sRGB`
+extensions to provide support for sRGB framebuffers.  Where both of these
+extensions are unavailable, the `GLFW_SRGB_CAPABLE` hint will have no effect.
+
+
+@section compat_wgl WGL extensions
+
+The WGL API is used to create OpenGL contexts on Microsoft Windows and other
+implementations of the Win32 API, such as Wine.
+
+GLFW uses either the `WGL_EXT_extension_string` or the
+`WGL_ARB_extension_string` extension to check for the presence of all other WGL
+extensions listed below.  If both are available, the EXT one is preferred.  If
+neither is available, no other extensions are used and many GLFW features
+related to context creation will have no effect or cause errors when used.
+
+GLFW uses the `WGL_EXT_swap_control` extension to provide vertical retrace
+synchronization (or _vsync_).  Where this extension is unavailable, calling @ref
+glfwSwapInterval will have no effect.
+
+GLFW uses the `WGL_ARB_pixel_format` and `WGL_ARB_multisample` extensions to
+create contexts with multisampling anti-aliasing.  Where these extensions are
+unavailable, the `GLFW_SAMPLES` hint will have no effect.
+
+GLFW uses the `WGL_ARB_create_context` extension when available, even when
+creating OpenGL contexts of version 2.1 and below.  Where this extension is
+unavailable, the `GLFW_CONTEXT_VERSION_MAJOR` and `GLFW_CONTEXT_VERSION_MINOR`
+hints will only be partially supported, the `GLFW_OPENGL_DEBUG_CONTEXT` hint
+will have no effect, and setting the `GLFW_OPENGL_PROFILE` or
+`GLFW_OPENGL_FORWARD_COMPAT` hints to `GLFW_TRUE` will cause @ref
+glfwCreateWindow to fail.
+
+GLFW uses the `WGL_ARB_create_context_profile` extension to provide support for
+context profiles.  Where this extension is unavailable, setting the
+`GLFW_OPENGL_PROFILE` hint to anything but `GLFW_OPENGL_ANY_PROFILE` will cause
+@ref glfwCreateWindow to fail.
+
+GLFW uses the `WGL_ARB_context_flush_control` extension to provide control over
+whether a context is flushed when it is released (made non-current).  Where this
+extension is unavailable, the `GLFW_CONTEXT_RELEASE_BEHAVIOR` hint will have no
+effect and the context will always be flushed when released.
+
+GLFW uses the `WGL_ARB_framebuffer_sRGB` and `WGL_EXT_framebuffer_sRGB`
+extensions to provide support for sRGB framebuffers.  Where both of these
+extension are unavailable, the `GLFW_SRGB_CAPABLE` hint will have no effect.
+
+
+@section compat_osx OpenGL on macOS
+
+Support for OpenGL 3.2 and above was introduced with OS X 10.7 and even then
+only forward-compatible, core profile contexts are supported.  Support for
+OpenGL 4.1 was introduced with OS X 10.9, also limited to forward-compatible,
+core profile contexts.  There is also still no mechanism for requesting debug
+contexts or no-error contexts.  Versions of Mac OS X earlier than 10.7 support
+at most OpenGL version 2.1.
+
+Because of this, on OS X 10.7 and later, the `GLFW_CONTEXT_VERSION_MAJOR` and
+`GLFW_CONTEXT_VERSION_MINOR` hints will cause @ref glfwCreateWindow to fail if
+given version 3.0 or 3.1.  The `GLFW_OPENGL_FORWARD_COMPAT` hint must be set to
+`GLFW_TRUE` and the `GLFW_OPENGL_PROFILE` hint must be set to
+`GLFW_OPENGL_CORE_PROFILE` when creating OpenGL 3.2 and later contexts.  The
+`GLFW_OPENGL_DEBUG_CONTEXT` and `GLFW_CONTEXT_NO_ERROR` hints are ignored.
+
+Also, on Mac OS X 10.6 and below, the `GLFW_CONTEXT_VERSION_MAJOR` and
+`GLFW_CONTEXT_VERSION_MINOR` hints will fail if given a version above 2.1,
+setting the `GLFW_OPENGL_PROFILE` or `GLFW_OPENGL_FORWARD_COMPAT` hints to
+a non-default value will cause @ref glfwCreateWindow to fail and the
+`GLFW_OPENGL_DEBUG_CONTEXT` hint is ignored.
+
+
+@section compat_vulkan Vulkan loader and API
+
+By default, GLFW uses the standard system-wide Vulkan loader to access the
+Vulkan API on all platforms except macOS.  This is installed by both graphics
+drivers and Vulkan SDKs.  If either the loader or at least one minimally
+functional ICD is missing, @ref glfwVulkanSupported will return `GLFW_FALSE` and
+all other Vulkan-related functions will fail with an @ref GLFW_API_UNAVAILABLE
+error.
+
+
+@section compat_wsi Vulkan WSI extensions
+
+The Vulkan WSI extensions are used to create Vulkan surfaces for GLFW windows on
+all supported platforms.
+
+GLFW uses the `VK_KHR_surface` and `VK_KHR_win32_surface` extensions to create
+surfaces on Microsoft Windows.  If any of these extensions are not available,
+@ref glfwGetRequiredInstanceExtensions will return an empty list and window
+surface creation will fail.
+
+GLFW uses the `VK_KHR_surface` and either the `VK_MVK_macos_surface` or
+`VK_EXT_metal_surface` extensions to create surfaces on macOS.  If any of these
+extensions are not available, @ref glfwGetRequiredInstanceExtensions will
+return an empty list and window surface creation will fail.
+
+GLFW uses the `VK_KHR_surface` and either the `VK_KHR_xlib_surface` or
+`VK_KHR_xcb_surface` extensions to create surfaces on X11.  If `VK_KHR_surface`
+or both `VK_KHR_xlib_surface` and `VK_KHR_xcb_surface` are not available, @ref
+glfwGetRequiredInstanceExtensions will return an empty list and window surface
+creation will fail.
+
+GLFW uses the `VK_KHR_surface` and `VK_KHR_wayland_surface` extensions to create
+surfaces on Wayland.  If any of these extensions are not available, @ref
+glfwGetRequiredInstanceExtensions will return an empty list and window surface
+creation will fail.

+
+@page compile_guide Compiling GLFW
+
+@tableofcontents
+
+This is about compiling the GLFW library itself.  For information on how to
+build applications that use GLFW, see @ref build_guide.
+
+
+@section compile_cmake Using CMake
+
+GLFW uses [CMake](https://cmake.org/) to generate project files or makefiles
+for a particular development environment.  If you are on a Unix-like system such
+as Linux or FreeBSD or have a package system like Fink, MacPorts, Cygwin or
+Homebrew, you can install its CMake package.  If not, you can download
+installers for Windows and macOS from the
+[CMake website](https://cmake.org/).
+
+@note CMake only generates project files or makefiles.  It does not compile the
+actual GLFW library.  To compile GLFW, first generate these files for your
+chosen development environment and then use them to compile the actual GLFW
+library.
+
+
+@subsection compile_deps Dependencies
+
+Once you have installed CMake, make sure that all other dependencies are
+available.  On some platforms, GLFW needs a few additional packages to be
+installed.  See the section for your chosen platform and development environment
+below.
+
+
+@subsubsection compile_deps_msvc Dependencies for Visual C++ on Windows
+
+The Windows SDK bundled with Visual C++ already contains all the necessary
+headers, link libraries and tools except for CMake.  Move on to @ref
+compile_generate.
+
+
+@subsubsection compile_deps_mingw Dependencies for MinGW or MinGW-w64 on Windows
+
+Both the MinGW and the MinGW-w64 packages already contain all the necessary
+headers, link libraries and tools except for CMake.  Move on to @ref
+compile_generate.
+
+
+@subsubsection compile_deps_mingw_cross Dependencies for MinGW or MinGW-w64 cross-compilation
+
+Both Cygwin and many Linux distributions have MinGW or MinGW-w64 packages.  For
+example, Cygwin has the `mingw64-i686-gcc` and `mingw64-x86_64-gcc` packages
+for 32- and 64-bit version of MinGW-w64, while Debian GNU/Linux and derivatives
+like Ubuntu have the `mingw-w64` package for both.
+
+GLFW has CMake toolchain files in the `CMake/` directory that set up
+cross-compilation of Windows binaries.  To use these files you add an option
+when running `cmake` to generate the project files or makefiles:
+
+@code{.sh}
+cmake -DCMAKE_TOOLCHAIN_FILE=<toolchain-file> .
+@endcode
+
+The exact toolchain file to use depends on the prefix used by the MinGW or
+MinGW-w64 binaries on your system.  You can usually see this in the /usr
+directory.  For example, both the Debian/Ubuntu and Cygwin MinGW-w64 packages
+have `/usr/x86_64-w64-mingw32` for the 64-bit compilers, so the correct
+invocation would be:
+
+@code{.sh}
+cmake -DCMAKE_TOOLCHAIN_FILE=CMake/x86_64-w64-mingw32.cmake .
+@endcode
+
+For more details see the article
+[CMake Cross Compiling](https://gitlab.kitware.com/cmake/community/wikis/doc/cmake/CrossCompiling) on
+the CMake wiki.
+
+Once you have this set up, move on to @ref compile_generate.
+
+
+@subsubsection compile_deps_xcode Dependencies for Xcode on macOS
+
+Xcode comes with all necessary tools except for CMake.  The required headers
+and libraries are included in the core macOS frameworks.  Xcode can be
+downloaded from the Mac App Store or from the ADC Member Center.
+
+Once you have Xcode installed, move on to @ref compile_generate.
+
+
+@subsubsection compile_deps_x11 Dependencies for Linux and X11
+
+To compile GLFW for X11, you need to have the X11 packages installed, as well as
+the basic development tools like GCC and make.  For example, on Ubuntu and other
+distributions based on Debian GNU/Linux, you need to install the `xorg-dev`
+package, which pulls in all X.org header packages.
+
+Once you have installed the necessary packages, move on to @ref
+compile_generate.
+
+
+@subsubsection compile_deps_wayland Dependencies for Linux and Wayland
+
+To compile GLFW for Wayland, you need to have the Wayland packages installed,
+as well as the basic development tools like GCC and make.  For example, on
+Ubuntu and other distributions based on Debian GNU/Linux, you need to install
+the `libwayland-dev` package, which contains all Wayland headers and pulls in
+wayland-scanner, as well as the `wayland-protocols` and `extra-cmake-modules`
+packages.
+
+Once you have installed the necessary packages, move on to @ref
+compile_generate.
+
+
+@subsection compile_deps_osmesa Dependencies for Linux and OSMesa
+
+To compile GLFW for OSMesa, you need to install the OSMesa library and header
+packages.  For example, on Ubuntu and other distributions based on Debian
+GNU/Linux, you need to install the `libosmesa6-dev` package.  The OSMesa library
+is required at runtime for context creation and is loaded on demand.
+
+Once you have installed the necessary packages, move on to @ref
+compile_generate.
+
+
+@subsection compile_generate Generating build files with CMake
+
+Once you have all necessary dependencies it is time to generate the project
+files or makefiles for your development environment.  CMake needs to know two
+paths for this: the path to the _root_ directory of the GLFW source tree (i.e.
+_not_ the `src` subdirectory) and the target path for the generated files and
+compiled binaries.  If these are the same, it is called an in-tree build,
+otherwise it is called an out-of-tree build.
+
+One of several advantages of out-of-tree builds is that you can generate files
+and compile for different development environments using a single source tree.
+
+@note This section is about generating the project files or makefiles necessary
+to compile the GLFW library, not about compiling the actual library.
+
+
+@subsubsection compile_generate_cli Generating files with the CMake command-line tool
+
+To make an in-tree build, enter the _root_ directory of the GLFW source tree
+(i.e. _not_ the `src` subdirectory) and run CMake.  The current directory is
+used as target path, while the path provided as an argument is used to find the
+source tree.
+
+@code{.sh}
+cd <glfw-root-dir>
+cmake .
+@endcode
+
+To make an out-of-tree build, make a directory outside of the source tree, enter
+it and run CMake with the (relative or absolute) path to the root of the source
+tree as an argument.
+
+@code{.sh}
+mkdir glfw-build
+cd glfw-build
+cmake <glfw-root-dir>
+@endcode
+
+Once you have generated the project files or makefiles for your chosen
+development environment, move on to @ref compile_compile.
+
+
+@subsubsection compile_generate_gui Generating files with the CMake GUI
+
+If you are using the GUI version, choose the root of the GLFW source tree as
+source location and the same directory or another, empty directory as the
+destination for binaries.  Choose _Configure_, change any options you wish to,
+_Configure_ again to let the changes take effect and then _Generate_.
+
+Once you have generated the project files or makefiles for your chosen
+development environment, move on to @ref compile_compile.
+
+
+@subsection compile_compile Compiling the library
+
+You should now have all required dependencies and the project files or makefiles
+necessary to compile GLFW.  Go ahead and compile the actual GLFW library with
+these files, as you would with any other project.
+
+Once the GLFW library is compiled, you are ready to build your applications,
+linking it to the GLFW library.  See @ref build_guide for more information.
+
+
+@subsection compile_options CMake options
+
+The CMake files for GLFW provide a number of options, although not all are
+available on all supported platforms.  Some of these are de facto standards
+among projects using CMake and so have no `GLFW_` prefix.
+
+If you are using the GUI version of CMake, these are listed and can be changed
+from there.  If you are using the command-line version of CMake you can use the
+`ccmake` ncurses GUI to set options.  Some package systems like Ubuntu and other
+distributions based on Debian GNU/Linux have this tool in a separate
+`cmake-curses-gui` package.
+
+Finally, if you don't want to use any GUI, you can set options from the `cmake`
+command-line with the `-D` flag.
+
+@code{.sh}
+cmake -DBUILD_SHARED_LIBS=ON .
+@endcode
+
+
+@subsubsection compile_options_shared Shared CMake options
+
+@anchor BUILD_SHARED_LIBS
+__BUILD_SHARED_LIBS__ determines whether GLFW is built as a static
+library or as a DLL / shared library / dynamic library.
+
+@anchor GLFW_BUILD_EXAMPLES
+__GLFW_BUILD_EXAMPLES__ determines whether the GLFW examples are built
+along with the library.
+
+@anchor GLFW_BUILD_TESTS
+__GLFW_BUILD_TESTS__ determines whether the GLFW test programs are
+built along with the library.
+
+@anchor GLFW_BUILD_DOCS
+__GLFW_BUILD_DOCS__ determines whether the GLFW documentation is built along
+with the library.
+
+@anchor GLFW_VULKAN_STATIC
+__GLFW_VULKAN_STATIC__ determines whether to use the Vulkan loader linked
+directly with the application.
+
+
+@subsubsection compile_options_win32 Windows specific CMake options
+
+@anchor USE_MSVC_RUNTIME_LIBRARY_DLL
+__USE_MSVC_RUNTIME_LIBRARY_DLL__ determines whether to use the DLL version or the
+static library version of the Visual C++ runtime library.  If set to `ON`, the
+DLL version of the Visual C++ library is used.
+
+@anchor GLFW_USE_HYBRID_HPG
+__GLFW_USE_HYBRID_HPG__ determines whether to export the `NvOptimusEnablement` and
+`AmdPowerXpressRequestHighPerformance` symbols, which force the use of the
+high-performance GPU on Nvidia Optimus and AMD PowerXpress systems.  These symbols
+need to be exported by the EXE to be detected by the driver, so the override
+will not work if GLFW is built as a DLL.
+
+
+@section compile_manual Compiling GLFW manually
+
+If you wish to compile GLFW without its CMake build environment then you will
+have to do at least some of the platform detection yourself.  GLFW needs
+a configuration macro to be defined in order to know what window system it's
+being compiled for and also has optional, platform-specific ones for various
+features.
+
+When building with CMake, the `glfw_config.h` configuration header is generated
+based on the current platform and CMake options.  The GLFW CMake environment
+defines @b GLFW_USE_CONFIG_H, which causes this header to be included by
+`internal.h`.  Without this macro, GLFW will expect the necessary configuration
+macros to be defined on the command-line.
+
+The window creation API is used to create windows, handle input, monitors, gamma
+ramps and clipboard.  The options are:
+
+ - @b _GLFW_COCOA to use the Cocoa frameworks
+ - @b _GLFW_WIN32 to use the Win32 API
+ - @b _GLFW_X11 to use the X Window System
+ - @b _GLFW_WAYLAND to use the Wayland API (experimental and incomplete)
+ - @b _GLFW_OSMESA to use the OSMesa API (headless and non-interactive)
+
+If you are building GLFW as a shared library / dynamic library / DLL then you
+must also define @b _GLFW_BUILD_DLL.  Otherwise, you must not define it.
+
+If you are linking the Vulkan loader directly with your application then you
+must also define @b _GLFW_VULKAN_STATIC.  Otherwise, GLFW will attempt to use the
+external version.
+
+If you are using a custom name for the Vulkan, EGL, GLX, OSMesa, OpenGL, GLESv1
+or GLESv2 library, you can override the default names by defining those you need
+of @b _GLFW_VULKAN_LIBRARY, @b _GLFW_EGL_LIBRARY, @b _GLFW_GLX_LIBRARY, @b
+_GLFW_OSMESA_LIBRARY, @b _GLFW_OPENGL_LIBRARY, @b _GLFW_GLESV1_LIBRARY and @b
+_GLFW_GLESV2_LIBRARY.  Otherwise, GLFW will use the built-in default names.
+
+For the EGL context creation API, the following options are available:
+
+ - @b _GLFW_USE_EGLPLATFORM_H to use an existing `EGL/eglplatform.h` header file
+   for native handle types (fallback)
+
+@note None of the @ref build_macros may be defined during the compilation of
+GLFW.  If you define any of these in your build files, make sure they are not
+applied to the GLFW sources.

+@page context_guide Context guide
+
+@tableofcontents
+
+This guide introduces the OpenGL and OpenGL ES context related functions of
+GLFW.  For details on a specific function in this category, see the @ref
+context.  There are also guides for the other areas of the GLFW API.
+
+ - @ref intro_guide
+ - @ref window_guide
+ - @ref vulkan_guide
+ - @ref monitor_guide
+ - @ref input_guide
+
+
+@section context_object Context objects
+
+A window object encapsulates both a top-level window and an OpenGL or OpenGL ES
+context.  It is created with @ref glfwCreateWindow and destroyed with @ref
+glfwDestroyWindow or @ref glfwTerminate.  See @ref window_creation for more
+information.
+
+As the window and context are inseparably linked, the window object also serves
+as the context handle.
+
+To test the creation of various kinds of contexts and see their properties, run
+the `glfwinfo` test program.
+
+@note Vulkan does not have a context and the Vulkan instance is created via the
+Vulkan API itself.  If you will be using Vulkan to render to a window, disable
+context creation by setting the [GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint)
+hint to `GLFW_NO_API`.  For more information, see the @ref vulkan_guide.
+
+
+@subsection context_hints Context creation hints
+
+There are a number of hints, specified using @ref glfwWindowHint, related to
+what kind of context is created.  See
+[context related hints](@ref window_hints_ctx) in the window guide.
+
+
+@subsection context_sharing Context object sharing
+
+When creating a window and its OpenGL or OpenGL ES context with @ref
+glfwCreateWindow, you can specify another window whose context the new one
+should share its objects (textures, vertex and element buffers, etc.) with.
+
+@code
+GLFWwindow* second_window = glfwCreateWindow(640, 480, "Second Window", NULL, first_window);
+@endcode
+
+Object sharing is implemented by the operating system and graphics driver.  On
+platforms where it is possible to choose which types of objects are shared, GLFW
+requests that all types are shared.
+
+See the relevant chapter of the [OpenGL](https://www.opengl.org/registry/) or
+[OpenGL ES](https://www.khronos.org/opengles/) reference documents for more
+information.  The name and number of this chapter unfortunately varies between
+versions and APIs, but has at times been named _Shared Objects and Multiple
+Contexts_.
+
+GLFW comes with a barebones object sharing example program called `sharing`.
+
+
+@subsection context_offscreen Offscreen contexts
+
+GLFW doesn't support creating contexts without an associated window.  However,
+contexts with hidden windows can be created with the
+[GLFW_VISIBLE](@ref GLFW_VISIBLE_hint) window hint.
+
+@code
+glfwWindowHint(GLFW_VISIBLE, GLFW_FALSE);
+
+GLFWwindow* offscreen_context = glfwCreateWindow(640, 480, "", NULL, NULL);
+@endcode
+
+The window never needs to be shown and its context can be used as a plain
+offscreen context.  Depending on the window manager, the size of a hidden
+window's framebuffer may not be usable or modifiable, so framebuffer
+objects are recommended for rendering with such contexts.
+
+You should still [process events](@ref events) as long as you have at least one
+window, even if none of them are visible.
+
+@macos The first time a window is created the menu bar is created.  This is not
+desirable for example when writing a command-line only application.  Menu bar
+creation can be disabled with the @ref GLFW_COCOA_MENUBAR init hint.
+
+
+@subsection context_less Windows without contexts
+
+You can disable context creation by setting the
+[GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint) hint to `GLFW_NO_API`.  Windows
+without contexts must not be passed to @ref glfwMakeContextCurrent or @ref
+glfwSwapBuffers.
+
+
+@section context_current Current context
+
+Before you can make OpenGL or OpenGL ES calls, you need to have a current
+context of the correct type.  A context can only be current for a single thread
+at a time, and a thread can only have a single context current at a time.
+
+When moving a context between threads, you must make it non-current on the old
+thread before making it current on the new one.
+
+The context of a window is made current with @ref glfwMakeContextCurrent.
+
+@code
+glfwMakeContextCurrent(window);
+@endcode
+
+The window of the current context is returned by @ref glfwGetCurrentContext.
+
+@code
+GLFWwindow* window = glfwGetCurrentContext();
+@endcode
+
+The following GLFW functions require a context to be current.  Calling any these
+functions without a current context will generate a @ref GLFW_NO_CURRENT_CONTEXT
+error.
+
+ - @ref glfwSwapInterval
+ - @ref glfwExtensionSupported
+ - @ref glfwGetProcAddress
+
+
+@section context_swap Buffer swapping
+
+See @ref buffer_swap in the window guide.
+
+
+@section context_glext OpenGL and OpenGL ES extensions
+
+One of the benefits of OpenGL and OpenGL ES is their extensibility.
+Hardware vendors may include extensions in their implementations that extend the
+API before that functionality is included in a new version of the OpenGL or
+OpenGL ES specification, and some extensions are never included and remain
+as extensions until they become obsolete.
+
+An extension is defined by:
+
+- An extension name (e.g. `GL_ARB_debug_output`)
+- New OpenGL tokens (e.g. `GL_DEBUG_SEVERITY_HIGH_ARB`)
+- New OpenGL functions (e.g. `glGetDebugMessageLogARB`)
+
+Note the `ARB` affix, which stands for Architecture Review Board and is used
+for official extensions.  The extension above was created by the ARB, but there
+are many different affixes, like `NV` for Nvidia and `AMD` for, well, AMD.  Any
+group may also use the generic `EXT` affix.  Lists of extensions, together with
+their specifications, can be found at the
+[OpenGL Registry](https://www.opengl.org/registry/) and
+[OpenGL ES Registry](https://www.khronos.org/registry/gles/).
+
+
+@subsection context_glext_auto Loading extension with a loader library
+
+An extension loader library is the easiest and best way to access both OpenGL and
+OpenGL ES extensions and modern versions of the core OpenGL or OpenGL ES APIs.
+They will take care of all the details of declaring and loading everything you
+need.  One such library is [glad](https://github.com/Dav1dde/glad) and there are
+several others.
+
+The following example will use glad but all extension loader libraries work
+similarly.
+
+First you need to generate the source files using the glad Python script.  This
+example generates a loader for any version of OpenGL, which is the default for
+both GLFW and glad, but loaders for OpenGL ES, as well as loaders for specific
+API versions and extension sets can be generated.  The generated files are
+written to the `output` directory.
+
+@code{.sh}
+python main.py --generator c --no-loader --out-path output
+@endcode
+
+The `--no-loader` option is added because GLFW already provides a function for
+loading OpenGL and OpenGL ES function pointers, one that automatically uses the
+selected context creation API, and glad can call this instead of having to
+implement its own.  There are several other command-line options as well.  See
+the glad documentation for details.
+
+Add the generated `output/src/glad.c`, `output/include/glad/glad.h` and
+`output/include/KHR/khrplatform.h` files to your build.  Then you need to
+include the glad header file, which will replace the OpenGL header of your
+development environment.  By including the glad header before the GLFW header,
+it suppresses the development environment's OpenGL or OpenGL ES header.
+
+@code
+#include <glad/glad.h>
+#include <GLFW/glfw3.h>
+@endcode
+
+Finally you need to initialize glad once you have a suitable current context.
+
+@code
+window = glfwCreateWindow(640, 480, "My Window", NULL, NULL);
+if (!window)
+{
+    ...
+}
+
+glfwMakeContextCurrent(window);
+
+gladLoadGLLoader((GLADloadproc) glfwGetProcAddress);
+@endcode
+
+Once glad has been loaded, you have access to all OpenGL core and extension
+functions supported by both the context you created and the glad loader you
+generated and you are ready to start rendering.
+
+You can specify a minimum required OpenGL or OpenGL ES version with
+[context hints](@ref window_hints_ctx).  If your needs are more complex, you can
+check the actual OpenGL or OpenGL ES version with
+[context attributes](@ref window_attribs_ctx), or you can check whether
+a specific version is supported by the current context with the
+`GLAD_GL_VERSION_x_x` booleans.
+
+@code
+if (GLAD_GL_VERSION_3_2)
+{
+    // Call OpenGL 3.2+ specific code
+}
+@endcode
+
+To check whether a specific extension is supported, use the `GLAD_GL_xxx`
+booleans.
+
+@code
+if (GLAD_GL_ARB_debug_output)
+{
+    // Use GL_ARB_debug_output
+}
+@endcode
+
+
+@subsection context_glext_manual Loading extensions manually
+
+__Do not use this technique__ unless it is absolutely necessary.  An
+[extension loader library](@ref context_glext_auto) will save you a ton of
+tedious, repetitive, error prone work.
+
+To use a certain extension, you must first check whether the context supports
+that extension and then, if it introduces new functions, retrieve the pointers
+to those functions.  GLFW provides @ref glfwExtensionSupported and @ref
+glfwGetProcAddress for manual loading of extensions and new API functions.
+
+This section will demonstrate manual loading of OpenGL extensions.  The loading
+of OpenGL ES extensions is identical except for the name of the extension header.
+
+
+@subsubsection context_glext_header The glext.h header
+
+The `glext.h` extension header is a continually updated file that defines the
+interfaces for all OpenGL extensions.  The latest version of this can always be
+found at the [OpenGL Registry](https://www.opengl.org/registry/).  There are also
+extension headers for the various versions of OpenGL ES at the
+[OpenGL ES Registry](https://www.khronos.org/registry/gles/).  It it strongly
+recommended that you use your own copy of the extension header, as the one
+included in your development environment may be several years out of date and
+may not include the extensions you wish to use.
+
+The header defines function pointer types for all functions of all extensions it
+supports.  These have names like `PFNGLGETDEBUGMESSAGELOGARBPROC` (for
+`glGetDebugMessageLogARB`), i.e. the name is made uppercase and `PFN` (pointer
+to function) and `PROC` (procedure) are added to the ends.
+
+To include the extension header, define @ref GLFW_INCLUDE_GLEXT before including
+the GLFW header.
+
+@code
+#define GLFW_INCLUDE_GLEXT
+#include <GLFW/glfw3.h>
+@endcode
+
+
+@subsubsection context_glext_string Checking for extensions
+
+A given machine may not actually support the extension (it may have older
+drivers or a graphics card that lacks the necessary hardware features), so it
+is necessary to check at run-time whether the context supports the extension.
+This is done with @ref glfwExtensionSupported.
+
+@code
+if (glfwExtensionSupported("GL_ARB_debug_output"))
+{
+    // The extension is supported by the current context
+}
+@endcode
+
+The argument is a null terminated ASCII string with the extension name.  If the
+extension is supported, @ref glfwExtensionSupported returns `GLFW_TRUE`,
+otherwise it returns `GLFW_FALSE`.
+
+
+@subsubsection context_glext_proc Fetching function pointers
+
+Many extensions, though not all, require the use of new OpenGL functions.
+These functions often do not have entry points in the client API libraries of
+your operating system, making it necessary to fetch them at run time.  You can
+retrieve pointers to these functions with @ref glfwGetProcAddress.
+
+@code
+PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog = glfwGetProcAddress("glGetDebugMessageLogARB");
+@endcode
+
+In general, you should avoid giving the function pointer variables the (exact)
+same name as the function, as this may confuse your linker.  Instead, you can
+use a different prefix, like above, or some other naming scheme.
+
+Now that all the pieces have been introduced, here is what they might look like
+when used together.
+
+@code
+#define GLFW_INCLUDE_GLEXT
+#include <GLFW/glfw3.h>
+
+#define glGetDebugMessageLogARB pfnGetDebugMessageLog
+PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog;
+
+// Flag indicating whether the extension is supported
+int has_ARB_debug_output = 0;
+
+void load_extensions(void)
+{
+    if (glfwExtensionSupported("GL_ARB_debug_output"))
+    {
+        pfnGetDebugMessageLog = (PFNGLGETDEBUGMESSAGELOGARBPROC)
+            glfwGetProcAddress("glGetDebugMessageLogARB");
+        has_ARB_debug_output = 1;
+    }
+}
+
+void some_function(void)
+{
+    if (has_ARB_debug_output)
+    {
+        // Now the extension function can be called as usual
+        glGetDebugMessageLogARB(...);
+    }
+}
+@endcode

For information on how to compile the GLFW library itself, see <a class="el" href="compile_guide.html">Compiling GLFW</a>.</p>
+<p>This is not a tutorial on compilation or linking. It assumes basic understanding of how to compile and link a C program as well as how to use the specific compiler of your chosen development environment. The compilation and linking process should be explained in your C programming material and in the documentation for your development environment.</p>
+<h1><a class="anchor" id="build_include"></a>
+Including the GLFW header file</h1>
+<p>You should include the GLFW header in the source files where you use OpenGL or GLFW.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#include &lt;<a class="code" href="glfw3_8h.html">GLFW/glfw3.h</a>&gt;</span></div>
+</div><!-- fragment --><p>This header declares the GLFW API and by default also includes the OpenGL header from your development environment. See below for how to control this.</p>
+<p>The GLFW header also defines any platform-specific macros needed by your OpenGL header, so it can be included without needing any window system headers.</p>
+<p>For example, under Windows you are normally required to include <code>windows.h</code> before the OpenGL header, which would bring in the whole Win32 API. The GLFW header duplicates the small number of macros needed.</p>
+<p>It does this only when needed, so if <code>windows.h</code> <em>is</em> included, the GLFW header does not try to redefine those symbols. The reverse is not true, i.e. <code>windows.h</code> cannot cope if any of its symbols have already been defined.</p>
+<p>In other words:</p>
+<ul>
+<li>Do <em>not</em> include the OpenGL headers yourself, as GLFW does this for you</li>
+<li>Do <em>not</em> include <code>windows.h</code> or other platform-specific headers unless you plan on using those APIs directly</li>
+<li>If you <em>do</em> need to include such headers, do it <em>before</em> including the GLFW header and it will handle this</li>
+</ul>
+<p>If you are using an OpenGL extension loading library such as <a href="https://github.com/Dav1dde/glad">glad</a>, the extension loader header should be included <em>before</em> the GLFW one.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#include &lt;glad/gl.h&gt;</span></div>

+<h1><a class="anchor" id="build_link"></a>
+Link with the right libraries</h1>
+<p>GLFW is essentially a wrapper of various platform-specific APIs and therefore needs to link against many different system libraries. If you are using GLFW as a shared library / dynamic library / DLL then it takes care of these links. However, if you are using GLFW as a static library then your executable will need to link against these libraries.</p>
+<p>On Windows and macOS, the list of system libraries is static and can be hard-coded into your build environment. See the section for your development environment below. On Linux and other Unix-like operating systems, the list varies but can be retrieved in various ways as described below.</p>
+<p>A good general introduction to linking is <a href="https://www.lurklurk.org/linkers/linkers.html">Beginner's Guide to Linkers</a> by David Drysdale.</p>
+<h2><a class="anchor" id="build_link_win32"></a>
+With MinGW or Visual C++ on Windows</h2>
+<p>The static version of the GLFW library is named <code>glfw3</code>. When using this version, it is also necessary to link with some libraries that GLFW uses.</p>
+<p>When using MinGW to link an application with the static version of GLFW, you must also explicitly link with <code>gdi32</code>. Other toolchains including MinGW-w64 include it in the set of default libraries along with other dependencies like <code>user32</code> and <code>kernel32</code>.</p>
+<p>The link library for the GLFW DLL is named <code>glfw3dll</code>. When compiling an application that uses the DLL version of GLFW, you need to define the <a class="el" href="build_guide.html#GLFW_DLL">GLFW_DLL</a> macro <em>before</em> any inclusion of the GLFW header. This can be done either with a compiler switch or by defining it in your source code.</p>
+<h2><a class="anchor" id="build_link_cmake_source"></a>
+With CMake and GLFW source</h2>
+<p>This section is about using CMake to compile and link GLFW along with your application. If you want to use an installed binary instead, see <a class="el" href="build_guide.html#build_link_cmake_package">With CMake and installed GLFW binaries</a>.</p>
+<p>With a few changes to your <code>CMakeLists.txt</code> you can have the GLFW source tree built along with your application.</p>
+<p>When including GLFW as part of your build, you probably don't want to build the GLFW tests, examples and documentation. To disable these, set the corresponding cache variables before adding the GLFW source tree.</p>
+<div class="fragment"><div class="line">set(GLFW_BUILD_DOCS OFF CACHE BOOL <span class="stringliteral">&quot;&quot;</span> FORCE)</div>
+<div class="line">set(GLFW_BUILD_TESTS OFF CACHE BOOL <span class="stringliteral">&quot;&quot;</span> FORCE)</div>
+<div class="line">set(GLFW_BUILD_EXAMPLES OFF CACHE BOOL <span class="stringliteral">&quot;&quot;</span> FORCE)</div>
+</div><!-- fragment --><p>Add the root directory of the GLFW source tree to your project. This will add the <code>glfw</code> target to your project.</p>
+<div class="fragment"><div class="line">add_subdirectory(path/to/glfw)</div>
+</div><!-- fragment --><p>Once GLFW has been added, link your application against the <code>glfw</code> target. This adds the GLFW library and its link-time dependencies as it is currently configured, the include directory for the GLFW header and, when applicable, the <a class="el" href="build_guide.html#GLFW_DLL">GLFW_DLL</a> macro.</p>
+<div class="fragment"><div class="line">target_link_libraries(myapp glfw)</div>
+</div><!-- fragment --><p>Note that the <code>glfw</code> target does not depend on OpenGL, as GLFW loads any OpenGL, OpenGL ES or Vulkan libraries it needs at runtime. If your application calls OpenGL directly, instead of using a modern <a class="el" href="context_guide.html#context_glext_auto">extension loader library</a>, use the OpenGL CMake package.</p>
+<div class="fragment"><div class="line">find_package(OpenGL REQUIRED)</div>
+</div><!-- fragment --><p>If OpenGL is found, the <code>OpenGL::GL</code> target is added to your project, containing library and include directory paths. Link against this like above.</p>
+<div class="fragment"><div class="line">target_link_libraries(myapp OpenGL::GL)</div>
+</div><!-- fragment --><h2><a class="anchor" id="build_link_cmake_package"></a>
+With CMake and installed GLFW binaries</h2>
+<p>This section is about using CMake to link GLFW after it has been built and installed. If you want to build it along with your application instead, see <a class="el" href="build_guide.html#build_link_cmake_source">With CMake and GLFW source</a>.</p>
+<p>With a few changes to your <code>CMakeLists.txt</code> you can locate the package and target files generated when GLFW is installed.</p>
+<div class="fragment"><div class="line">find_package(glfw3 3.3 REQUIRED)</div>
+</div><!-- fragment --><p>Once GLFW has been added to the project, link against it with the <code>glfw</code> target. This adds the GLFW library and its link-time dependencies, the include directory for the GLFW header and, when applicable, the <a class="el" href="build_guide.html#GLFW_DLL">GLFW_DLL</a> macro.</p>
+<div class="fragment"><div class="line">target_link_libraries(myapp glfw)</div>
+</div><!-- fragment --><p>Note that the <code>glfw</code> target does not depend on OpenGL, as GLFW loads any OpenGL, OpenGL ES or Vulkan libraries it needs at runtime. If your application calls OpenGL directly, instead of using a modern <a class="el" href="context_guide.html#context_glext_auto">extension loader library</a>, use the OpenGL CMake package.</p>
+<div class="fragment"><div class="line">find_package(OpenGL REQUIRED)</div>
+</div><!-- fragment --><p>If OpenGL is found, the <code>OpenGL::GL</code> target is added to your project, containing library and include directory paths. Link against this like above.</p>
+<div class="fragment"><div class="line">target_link_libraries(myapp OpenGL::GL)</div>
+</div><!-- fragment --><h2><a class="anchor" id="build_link_pkgconfig"></a>
+With makefiles and pkg-config on Unix</h2>
+<p>GLFW supports <a href="https://www.freedesktop.org/wiki/Software/pkg-config/">pkg-config</a>, and the <code>glfw3.pc</code> pkg-config file is generated when the GLFW library is built and is installed along with it. A pkg-config file describes all necessary compile-time and link-time flags and dependencies needed to use a library. When they are updated or if they differ between systems, you will get the correct ones automatically.</p>
+<p>A typical compile and link command-line when using the static version of the GLFW library may look like this:</p>
+<div class="fragment"><div class="line">cc $(pkg-config --cflags glfw3) -o myprog myprog.c $(pkg-config --static --libs glfw3)</div>
+</div><!-- fragment --><p>If you are using the shared version of the GLFW library, omit the <code>--static</code> flag.</p>
+<div class="fragment"><div class="line">cc $(pkg-config --cflags glfw3) -o myprog myprog.c $(pkg-config --libs glfw3)</div>
+</div><!-- fragment --><p>You can also use the <code>glfw3.pc</code> file without installing it first, by using the <code>PKG_CONFIG_PATH</code> environment variable.</p>
+<div class="fragment"><div class="line">env PKG_CONFIG_PATH=path/to/glfw/src cc $(pkg-config --cflags glfw3) -o myprog myprog.c $(pkg-config --libs glfw3)</div>
+</div><!-- fragment --><p>The dependencies do not include OpenGL, as GLFW loads any OpenGL, OpenGL ES or Vulkan libraries it needs at runtime. If your application calls OpenGL directly, instead of using a modern <a class="el" href="context_guide.html#context_glext_auto">extension loader library</a>, you should add the <code>gl</code> pkg-config package.</p>
+<div class="fragment"><div class="line">cc $(pkg-config --cflags glfw3 gl) -o myprog myprog.c $(pkg-config --libs glfw3 gl)</div>
+</div><!-- fragment --><h2><a class="anchor" id="build_link_xcode"></a>
+With Xcode on macOS</h2>
+<p>If you are using the dynamic library version of GLFW, add it to the project dependencies.</p>
+<p>If you are using the static library version of GLFW, add it and the Cocoa, OpenGL and IOKit frameworks to the project as dependencies. They can all be found in <code>/System/Library/Frameworks</code>.</p>
+<h2><a class="anchor" id="build_link_osx"></a>
+With command-line on macOS</h2>
+<p>It is recommended that you use <a class="el" href="build_guide.html#build_link_pkgconfig">pkg-config</a> when building from the command line on macOS. That way you will get any new dependencies added automatically. If you still wish to build manually, you need to add the required frameworks and libraries to your command-line yourself using the <code>-l</code> and <code>-framework</code> switches.</p>
+<p>If you are using the dynamic GLFW library, which is named <code>libglfw.3.dylib</code>, do:</p>
+<div class="fragment"><div class="line">cc -o myprog myprog.c -lglfw -framework Cocoa -framework OpenGL -framework IOKit</div>
+</div><!-- fragment --><p>If you are using the static library, named <code>libglfw3.a</code>, substitute <code>-lglfw3</code> for <code>-lglfw</code>.</p>
+<p>Note that you do not add the <code>.framework</code> extension to a framework when linking against it from the command-line.</p>
+<dl class="section note"><dt>Note</dt><dd>Your machine may have <code>libGL.*.dylib</code> style OpenGL library, but that is for the X Window System and will not work with the macOS native version of GLFW. </dd></dl>

+<div class="textblock"><p>This guide describes the various API extensions used by this version of GLFW. It lists what are essentially implementation details, but which are nonetheless vital knowledge for developers intending to deploy their applications on a wide range of machines.</p>
+<p>The information in this guide is not a part of GLFW API, but merely preconditions for some parts of the library to function on a given machine. Any part of this information may change in future versions of GLFW and that will not be considered a breaking API change.</p>
+<h1><a class="anchor" id="compat_x11"></a>
+X11 extensions, protocols and IPC standards</h1>
+<p>As GLFW uses Xlib directly, without any intervening toolkit library, it has sole responsibility for interacting well with the many and varied window managers in use on Unix-like systems. In order for applications and window managers to work well together, a number of standards and conventions have been developed that regulate behavior outside the scope of the X11 API; most importantly the <a href="https://www.tronche.com/gui/x/icccm/">Inter-Client Communication Conventions Manual</a> (ICCCM) and <a href="https://standards.freedesktop.org/wm-spec/wm-spec-latest.html">Extended Window Manager Hints</a> (EWMH) standards.</p>
+<p>GLFW uses the <code>_MOTIF_WM_HINTS</code> window property to support borderless windows. If the running window manager does not support this property, the <code>GLFW_DECORATED</code> hint will have no effect.</p>
+<p>GLFW uses the ICCCM <code>WM_DELETE_WINDOW</code> protocol to intercept the user attempting to close the GLFW window. If the running window manager does not support this protocol, the close callback will never be called.</p>
+<p>GLFW uses the EWMH <code>_NET_WM_PING</code> protocol, allowing the window manager notify the user when the application has stopped responding, i.e. when it has ceased to process events. If the running window manager does not support this protocol, the user will not be notified if the application locks up.</p>
+<p>GLFW uses the EWMH <code>_NET_WM_STATE_FULLSCREEN</code> window state to tell the window manager to make the GLFW window full screen. If the running window manager does not support this state, full screen windows may not work properly. GLFW has a fallback code path in case this state is unavailable, but every window manager behaves slightly differently in this regard.</p>
+<p>GLFW uses the EWMH <code>_NET_WM_BYPASS_COMPOSITOR</code> window property to tell a compositing window manager to un-redirect full screen GLFW windows. If the running window manager uses compositing but does not support this property then additional copying may be performed for each buffer swap of full screen windows.</p>
+<p>GLFW uses the <a href="https://www.freedesktop.org/wiki/ClipboardManager/">clipboard manager protocol</a> to push a clipboard string (i.e. selection) owned by a GLFW window about to be destroyed to the clipboard manager. If there is no running clipboard manager, the clipboard string will be unavailable once the window has been destroyed.</p>
+<p>GLFW uses the <a href="https://www.freedesktop.org/wiki/Specifications/XDND/">X drag-and-drop protocol</a> to provide file drop events. If the application originating the drag does not support this protocol, drag and drop will not work.</p>
+<p>GLFW uses the XRandR 1.3 extension to provide multi-monitor support. If the running X server does not support this version of this extension, multi-monitor support will not function and only a single, desktop-spanning monitor will be reported.</p>
+<p>GLFW uses the XRandR 1.3 and Xf86vidmode extensions to provide gamma ramp support. If the running X server does not support either or both of these extensions, gamma ramp support will not function.</p>
+<p>GLFW uses the Xkb extension and detectable auto-repeat to provide keyboard input. If the running X server does not support this extension, a non-Xkb fallback path is used.</p>
+<p>GLFW uses the XInput2 extension to provide raw, non-accelerated mouse motion when the cursor is disabled. If the running X server does not support this extension, regular accelerated mouse motion will be used.</p>
+<p>GLFW uses both the XRender extension and the compositing manager to support transparent window framebuffers. If the running X server does not support this extension or there is no running compositing manager, the <code>GLFW_TRANSPARENT_FRAMEBUFFER</code> framebuffer hint will have no effect.</p>
+<h1><a class="anchor" id="compat_wayland"></a>
+Wayland protocols and IPC standards</h1>
+<p>As GLFW uses libwayland directly, without any intervening toolkit library, it has sole responsibility for interacting well with every compositor in use on Unix-like systems. Most of the features are provided by the core protocol, while cursor support is provided by the libwayland-cursor helper library, EGL integration by libwayland-egl, and keyboard handling by <a href="https://xkbcommon.org/">libxkbcommon</a>. In addition, GLFW uses some protocols from wayland-protocols to provide additional features if the compositor supports them.</p>
+<p>GLFW uses xkbcommon 0.5.0 to provide compose key support. When it has been built against an older xkbcommon, the compose key will be disabled even if it has been configured in the compositor.</p>
+<p>GLFW uses the <a href="https://cgit.freedesktop.org/wayland/wayland-protocols/tree/stable/xdg-shell/xdg-shell.xml">xdg-shell protocol</a> to provide better window management. This protocol is part of wayland-protocols 1.12, and mandatory at build time. If the running compositor does not support this protocol, the older <a href="https://cgit.freedesktop.org/wayland/wayland/tree/protocol/wayland.xml#n972">wl_shell interface</a> will be used instead. This will result in a worse integration with the desktop, especially on tiling compositors.</p>
+<p>GLFW uses the <a href="https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/relative-pointer/relative-pointer-unstable-v1.xml">relative pointer protocol</a> alongside the <a href="https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/pointer-constraints/pointer-constraints-unstable-v1.xml">pointer constraints protocol</a> to implement disabled cursor. These two protocols are part of wayland-protocols 1.1, and mandatory at build time. If the running compositor does not support both of these protocols, disabling the cursor will have no effect.</p>
+<p>GLFW uses the <a href="https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/idle-inhibit/idle-inhibit-unstable-v1.xml">idle inhibit protocol</a> to prohibit the screensaver from starting. This protocol is part of wayland-protocols 1.6, and mandatory at build time. If the running compositor does not support this protocol, the screensaver may start even for full screen windows.</p>
+<p>GLFW uses the <a href="https://cgit.freedesktop.org/wayland/wayland-protocols/tree/unstable/xdg-decoration/xdg-decoration-unstable-v1.xml">xdg-decoration protocol</a> to request decorations to be drawn around its windows. This protocol is part of wayland-protocols 1.15, and mandatory at build time. If the running compositor does not support this protocol, a very simple frame will be drawn by GLFW itself, using the <a href="https://cgit.freedesktop.org/wayland/wayland-protocols/tree/stable/viewporter/viewporter.xml">viewporter protocol</a> alongside <a href="https://cgit.freedesktop.org/wayland/wayland/tree/protocol/wayland.xml#n2598">subsurfaces</a>. This protocol is part of wayland-protocols 1.4, and mandatory at build time. If the running compositor does not support this protocol either, no decorations will be drawn around windows.</p>
+<h1><a class="anchor" id="compat_glx"></a>
+GLX extensions</h1>
+<p>The GLX API is the default API used to create OpenGL contexts on Unix-like systems using the X Window System.</p>
+<p>GLFW uses the GLX 1.3 <code>GLXFBConfig</code> functions to enumerate and select framebuffer pixel formats. If GLX 1.3 is not supported, <a class="el" href="group__init.html#ga317aac130a235ab08c6db0834907d85e">glfwInit</a> will fail.</p>
+<p>GLFW uses the <code>GLX_MESA_swap_control,</code> <code>GLX_EXT_swap_control</code> and <code>GLX_SGI_swap_control</code> extensions to provide vertical retrace synchronization (or <em>vsync</em>), in that order of preference. Where none of these extension are available, calling <a class="el" href="group__context.html#ga6d4e0cdf151b5e579bd67f13202994ed">glfwSwapInterval</a> will have no effect.</p>
+<p>GLFW uses the <code>GLX_ARB_multisample</code> extension to create contexts with multisampling anti-aliasing. Where this extension is unavailable, the <code>GLFW_SAMPLES</code> hint will have no effect.</p>
+<p>GLFW uses the <code>GLX_ARB_create_context</code> extension when available, even when creating OpenGL contexts of version 2.1 and below. Where this extension is unavailable, the <code>GLFW_CONTEXT_VERSION_MAJOR</code> and <code>GLFW_CONTEXT_VERSION_MINOR</code> hints will only be partially supported, the <code>GLFW_OPENGL_DEBUG_CONTEXT</code> hint will have no effect, and setting the <code>GLFW_OPENGL_PROFILE</code> or <code>GLFW_OPENGL_FORWARD_COMPAT</code> hints to <code>GLFW_TRUE</code> will cause <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> to fail.</p>
+<p>GLFW uses the <code>GLX_ARB_create_context_profile</code> extension to provide support for context profiles. Where this extension is unavailable, setting the <code>GLFW_OPENGL_PROFILE</code> hint to anything but <code>GLFW_OPENGL_ANY_PROFILE</code>, or setting <code>GLFW_CLIENT_API</code> to anything but <code>GLFW_OPENGL_API</code> or <code>GLFW_NO_API</code> will cause <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> to fail.</p>
+<p>GLFW uses the <code>GLX_ARB_context_flush_control</code> extension to provide control over whether a context is flushed when it is released (made non-current). Where this extension is unavailable, the <code>GLFW_CONTEXT_RELEASE_BEHAVIOR</code> hint will have no effect and the context will always be flushed when released.</p>
+<p>GLFW uses the <code>GLX_ARB_framebuffer_sRGB</code> and <code>GLX_EXT_framebuffer_sRGB</code> extensions to provide support for sRGB framebuffers. Where both of these extensions are unavailable, the <code>GLFW_SRGB_CAPABLE</code> hint will have no effect.</p>
+<h1><a class="anchor" id="compat_wgl"></a>
+WGL extensions</h1>
+<p>The WGL API is used to create OpenGL contexts on Microsoft Windows and other implementations of the Win32 API, such as Wine.</p>
+<p>GLFW uses either the <code>WGL_EXT_extension_string</code> or the <code>WGL_ARB_extension_string</code> extension to check for the presence of all other WGL extensions listed below. If both are available, the EXT one is preferred. If neither is available, no other extensions are used and many GLFW features related to context creation will have no effect or cause errors when used.</p>
+<p>GLFW uses the <code>WGL_EXT_swap_control</code> extension to provide vertical retrace synchronization (or <em>vsync</em>). Where this extension is unavailable, calling <a class="el" href="group__context.html#ga6d4e0cdf151b5e579bd67f13202994ed">glfwSwapInterval</a> will have no effect.</p>
+<p>GLFW uses the <code>WGL_ARB_pixel_format</code> and <code>WGL_ARB_multisample</code> extensions to create contexts with multisampling anti-aliasing. Where these extensions are unavailable, the <code>GLFW_SAMPLES</code> hint will have no effect.</p>
+<p>GLFW uses the <code>WGL_ARB_create_context</code> extension when available, even when creating OpenGL contexts of version 2.1 and below. Where this extension is unavailable, the <code>GLFW_CONTEXT_VERSION_MAJOR</code> and <code>GLFW_CONTEXT_VERSION_MINOR</code> hints will only be partially supported, the <code>GLFW_OPENGL_DEBUG_CONTEXT</code> hint will have no effect, and setting the <code>GLFW_OPENGL_PROFILE</code> or <code>GLFW_OPENGL_FORWARD_COMPAT</code> hints to <code>GLFW_TRUE</code> will cause <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> to fail.</p>
+<p>GLFW uses the <code>WGL_ARB_create_context_profile</code> extension to provide support for context profiles. Where this extension is unavailable, setting the <code>GLFW_OPENGL_PROFILE</code> hint to anything but <code>GLFW_OPENGL_ANY_PROFILE</code> will cause <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> to fail.</p>
+<p>GLFW uses the <code>WGL_ARB_context_flush_control</code> extension to provide control over whether a context is flushed when it is released (made non-current). Where this extension is unavailable, the <code>GLFW_CONTEXT_RELEASE_BEHAVIOR</code> hint will have no effect and the context will always be flushed when released.</p>
+<p>GLFW uses the <code>WGL_ARB_framebuffer_sRGB</code> and <code>WGL_EXT_framebuffer_sRGB</code> extensions to provide support for sRGB framebuffers. Where both of these extension are unavailable, the <code>GLFW_SRGB_CAPABLE</code> hint will have no effect.</p>
+<h1><a class="anchor" id="compat_osx"></a>
+OpenGL on macOS</h1>
+<p>Support for OpenGL 3.2 and above was introduced with OS X 10.7 and even then only forward-compatible, core profile contexts are supported. Support for OpenGL 4.1 was introduced with OS X 10.9, also limited to forward-compatible, core profile contexts. There is also still no mechanism for requesting debug contexts or no-error contexts. Versions of Mac OS X earlier than 10.7 support at most OpenGL version 2.1.</p>
+<p>Because of this, on OS X 10.7 and later, the <code>GLFW_CONTEXT_VERSION_MAJOR</code> and <code>GLFW_CONTEXT_VERSION_MINOR</code> hints will cause <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> to fail if given version 3.0 or 3.1. The <code>GLFW_OPENGL_FORWARD_COMPAT</code> hint must be set to <code>GLFW_TRUE</code> and the <code>GLFW_OPENGL_PROFILE</code> hint must be set to <code>GLFW_OPENGL_CORE_PROFILE</code> when creating OpenGL 3.2 and later contexts. The <code>GLFW_OPENGL_DEBUG_CONTEXT</code> and <code>GLFW_CONTEXT_NO_ERROR</code> hints are ignored.</p>
+<p>Also, on Mac OS X 10.6 and below, the <code>GLFW_CONTEXT_VERSION_MAJOR</code> and <code>GLFW_CONTEXT_VERSION_MINOR</code> hints will fail if given a version above 2.1, setting the <code>GLFW_OPENGL_PROFILE</code> or <code>GLFW_OPENGL_FORWARD_COMPAT</code> hints to a non-default value will cause <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> to fail and the <code>GLFW_OPENGL_DEBUG_CONTEXT</code> hint is ignored.</p>
+<h1><a class="anchor" id="compat_vulkan"></a>
+Vulkan loader and API</h1>
+<p>By default, GLFW uses the standard system-wide Vulkan loader to access the Vulkan API on all platforms except macOS. This is installed by both graphics drivers and Vulkan SDKs. If either the loader or at least one minimally functional ICD is missing, <a class="el" href="group__vulkan.html#ga2e7f30931e02464b5bc8d0d4b6f9fe2b">glfwVulkanSupported</a> will return <code>GLFW_FALSE</code> and all other Vulkan-related functions will fail with an <a class="el" href="group__errors.html#ga56882b290db23261cc6c053c40c2d08e">GLFW_API_UNAVAILABLE</a> error.</p>
+<h1><a class="anchor" id="compat_wsi"></a>
+Vulkan WSI extensions</h1>
+<p>The Vulkan WSI extensions are used to create Vulkan surfaces for GLFW windows on all supported platforms.</p>
+<p>GLFW uses the <code>VK_KHR_surface</code> and <code>VK_KHR_win32_surface</code> extensions to create surfaces on Microsoft Windows. If any of these extensions are not available, <a class="el" href="group__vulkan.html#ga1abcbe61033958f22f63ef82008874b1">glfwGetRequiredInstanceExtensions</a> will return an empty list and window surface creation will fail.</p>
+<p>GLFW uses the <code>VK_KHR_surface</code> and either the <code>VK_MVK_macos_surface</code> or <code>VK_EXT_metal_surface</code> extensions to create surfaces on macOS. If any of these extensions are not available, <a class="el" href="group__vulkan.html#ga1abcbe61033958f22f63ef82008874b1">glfwGetRequiredInstanceExtensions</a> will return an empty list and window surface creation will fail.</p>
+<p>GLFW uses the <code>VK_KHR_surface</code> and either the <code>VK_KHR_xlib_surface</code> or <code>VK_KHR_xcb_surface</code> extensions to create surfaces on X11. If <code>VK_KHR_surface</code> or both <code>VK_KHR_xlib_surface</code> and <code>VK_KHR_xcb_surface</code> are not available, <a class="el" href="group__vulkan.html#ga1abcbe61033958f22f63ef82008874b1">glfwGetRequiredInstanceExtensions</a> will return an empty list and window surface creation will fail.</p>
+<p>GLFW uses the <code>VK_KHR_surface</code> and <code>VK_KHR_wayland_surface</code> extensions to create surfaces on Wayland.

+<h1><a class="anchor" id="compile_cmake"></a>
+Using CMake</h1>
+<p>GLFW uses <a href="https://cmake.org/">CMake</a> to generate project files or makefiles for a particular development environment. If you are on a Unix-like system such as Linux or FreeBSD or have a package system like Fink, MacPorts, Cygwin or Homebrew, you can install its CMake package. If not, you can download installers for Windows and macOS from the <a href="https://cmake.org/">CMake website</a>.</p>
+<dl class="section note"><dt>Note</dt><dd>CMake only generates project files or makefiles. It does not compile the actual GLFW library. To compile GLFW, first generate these files for your chosen development environment and then use them to compile the actual GLFW library.</dd></dl>
+<h2><a class="anchor" id="compile_deps"></a>
+Dependencies</h2>
+<p>Once you have installed CMake, make sure that all other dependencies are available. On some platforms, GLFW needs a few additional packages to be installed. See the section for your chosen platform and development environment below.</p>
+<h3><a class="anchor" id="compile_deps_msvc"></a>
+Dependencies for Visual C++ on Windows</h3>
+<p>The Windows SDK bundled with Visual C++ already contains all the necessary headers, link libraries and tools except for CMake. Move on to <a class="el" href="compile_guide.html#compile_generate">Generating build files with CMake</a>.</p>
+<h3><a class="anchor" id="compile_deps_mingw"></a>
+Dependencies for MinGW or MinGW-w64 on Windows</h3>
+<p>Both the MinGW and the MinGW-w64 packages already contain all the necessary headers, link libraries and tools except for CMake. Move on to <a class="el" href="compile_guide.html#compile_generate">Generating build files with CMake</a>.</p>
+<h3><a class="anchor" id="compile_deps_mingw_cross"></a>
+Dependencies for MinGW or MinGW-w64 cross-compilation</h3>
+<p>Both Cygwin and many Linux distributions have MinGW or MinGW-w64 packages. For example, Cygwin has the <code>mingw64-i686-gcc</code> and <code>mingw64-x86_64-gcc</code> packages for 32- and 64-bit version of MinGW-w64, while Debian GNU/Linux and derivatives like Ubuntu have the <code>mingw-w64</code> package for both.</p>
+<p>GLFW has CMake toolchain files in the <code>CMake/</code> directory that set up cross-compilation of Windows binaries. To use these files you add an option when running <code>cmake</code> to generate the project files or makefiles:</p>
+<div class="fragment"><div class="line">cmake -DCMAKE_TOOLCHAIN_FILE=&lt;toolchain-file&gt; .</div>
+</div><!-- fragment --><p>The exact toolchain file to use depends on the prefix used by the MinGW or MinGW-w64 binaries on your system. You can usually see this in the /usr directory. For example, both the Debian/Ubuntu and Cygwin MinGW-w64 packages have <code>/usr/x86_64-w64-mingw32</code> for the 64-bit compilers, so the correct invocation would be:</p>
+<div class="fragment"><div class="line">cmake -DCMAKE_TOOLCHAIN_FILE=CMake/x86_64-w64-mingw32.cmake .</div>
+</div><!-- fragment --><p>For more details see the article <a href="https://gitlab.kitware.com/cmake/community/wikis/doc/cmake/CrossCompiling">CMake Cross Compiling</a> on the CMake wiki.</p>
+<p>Once you have this set up, move on to <a class="el" href="compile_guide.html#compile_generate">Generating build files with CMake</a>.</p>
+<h3><a class="anchor" id="compile_deps_xcode"></a>
+Dependencies for Xcode on macOS</h3>
+<p>Xcode comes with all necessary tools except for CMake. The required headers and libraries are included in the core macOS frameworks. Xcode can be downloaded from the Mac App Store or from the ADC Member Center.</p>
+<p>Once you have Xcode installed, move on to <a class="el" href="compile_guide.html#compile_generate">Generating build files with CMake</a>.</p>
+<h3><a class="anchor" id="compile_deps_x11"></a>
+Dependencies for Linux and X11</h3>
+<p>To compile GLFW for X11, you need to have the X11 packages installed, as well as the basic development tools like GCC and make. For example, on Ubuntu and other distributions based on Debian GNU/Linux, you need to install the <code>xorg-dev</code> package, which pulls in all X.org header packages.</p>
+<p>Once you have installed the necessary packages, move on to <a class="el" href="compile_guide.html#compile_generate">Generating build files with CMake</a>.</p>
+<h3><a class="anchor" id="compile_deps_wayland"></a>
+Dependencies for Linux and Wayland</h3>
+<p>To compile GLFW for Wayland, you need to have the Wayland packages installed, as well as the basic development tools like GCC and make. For example, on Ubuntu and other distributions based on Debian GNU/Linux, you need to install the <code>libwayland-dev</code> package, which contains all Wayland headers and pulls in wayland-scanner, as well as the <code>wayland-protocols</code> and <code>extra-cmake-modules</code> packages.</p>
+<p>Once you have installed the necessary packages, move on to <a class="el" href="compile_guide.html#compile_generate">Generating build files with CMake</a>.</p>
+<h2><a class="anchor" id="compile_deps_osmesa"></a>
+Dependencies for Linux and OSMesa</h2>
+<p>To compile GLFW for OSMesa, you need to install the OSMesa library and header packages. For example, on Ubuntu and other distributions based on Debian GNU/Linux, you need to install the <code>libosmesa6-dev</code> package. The OSMesa library is required at runtime for context creation and is loaded on demand.</p>
+<p>Once you have installed the necessary packages, move on to <a class="el" href="compile_guide.html#compile_generate">Generating build files with CMake</a>.</p>
+<h2><a class="anchor" id="compile_generate"></a>
+Generating build files with CMake</h2>
+<p>Once you have all necessary dependencies it is time to generate the project files or makefiles for your development environment. CMake needs to know two paths for this: the path to the <em>root</em> directory of the GLFW source tree (i.e. <em>not</em> the <code>src</code> subdirectory) and the target path for the generated files and compiled binaries. If these are the same, it is called an in-tree build, otherwise it is called an out-of-tree build.</p>
+<p>One of several advantages of out-of-tree builds is that you can generate files and compile for different development environments using a single source tree.</p>
+<dl class="section note"><dt>Note</dt><dd>This section is about generating the project files or makefiles necessary to compile the GLFW library, not about compiling the actual library.</dd></dl>
+<h3><a class="anchor" id="compile_generate_cli"></a>
+Generating files with the CMake command-line tool</h3>
+<p>To make an in-tree build, enter the <em>root</em> directory of the GLFW source tree (i.e. <em>not</em> the <code>src</code> subdirectory) and run CMake. The current directory is used as target path, while the path provided as an argument is used to find the source tree.</p>
+<div class="fragment"><div class="line">cd &lt;glfw-root-dir&gt;</div>
+<div class="line">cmake .</div>
+</div><!-- fragment --><p>To make an out-of-tree build, make a directory outside of the source tree, enter it and run CMake with the (relative or absolute) path to the root of the source tree as an argument.</p>
+<div class="fragment"><div class="line">mkdir glfw-build</div>
+<div class="line">cd glfw-build</div>
+<div class="line">cmake &lt;glfw-root-dir&gt;</div>
+</div><!-- fragment --><p>Once you have generated the project files or makefiles for your chosen development environment, move on to <a class="el" href="compile_guide.html#compile_compile">Compiling the library</a>.</p>
+<h3><a class="anchor" id="compile_generate_gui"></a>
+Generating files with the CMake GUI</h3>
+<p>If you are using the GUI version, choose the root of the GLFW source tree as source location and the same directory or another, empty directory as the destination for binaries. Choose <em>Configure</em>, change any options you wish to, <em>Configure</em> again to let the changes take effect and then <em>Generate</em>.</p>
+<p>Once you have generated the project files or makefiles for your chosen development environment, move on to <a class="el" href="compile_guide.html#compile_compile">Compiling the library</a>.</p>
+<h2><a class="anchor" id="compile_compile"></a>
+Compiling the library</h2>
+<p>You should now have all required dependencies and the project files or makefiles necessary to compile GLFW. Go ahead and compile the actual GLFW library with these files, as you would with any other project.</p>
+<p>Once the GLFW library is compiled, you are ready to build your applications, linking it to the GLFW library. See <a class="el" href="build_guide.html">Building applications</a> for more information.</p>
+<h2><a class="anchor" id="compile_options"></a>
+CMake options</h2>
+<p>The CMake files for GLFW provide a number of options, although not all are available on all supported platforms. Some of these are de facto standards among projects using CMake and so have no <code>GLFW_</code> prefix.</p>
+<p>If you are using the GUI version of CMake, these are listed and can be changed from there. If you are using the command-line version of CMake you can use the <code>ccmake</code> ncurses GUI to set options. Some package systems like Ubuntu and other distributions based on Debian GNU/Linux have this tool in a separate <code>cmake-curses-gui</code> package.</p>
+<p>Finally, if you don't want to use any GUI, you can set options from the <code>cmake</code> command-line with the <code>-D</code> flag.</p>
+<div class="fragment"><div class="line">cmake -DBUILD_SHARED_LIBS=ON .</div>
+</div><!-- fragment --><h3><a class="anchor" id="compile_options_shared"></a>
+Shared CMake options</h3>
+<p><a class="anchor" id="BUILD_SHARED_LIBS"></a><b>BUILD_SHARED_LIBS</b> determines whether GLFW is built as a static library or as a DLL / shared library / dynamic library.</p>
+<p><a class="anchor" id="GLFW_BUILD_EXAMPLES"></a><b>GLFW_BUILD_EXAMPLES</b> determines whether the GLFW examples are built along with the library.</p>
+<p><a class="anchor" id="GLFW_BUILD_TESTS"></a><b>GLFW_BUILD_TESTS</b> determines whether the GLFW test programs are built along with the library.</p>
+<p><a class="anchor" id="GLFW_BUILD_DOCS"></a><b>GLFW_BUILD_DOCS</b> determines whether the GLFW documentation is built along with the library.</p>
+<p><a class="anchor" id="GLFW_VULKAN_STATIC"></a><b>GLFW_VULKAN_STATIC</b> determines whether to use the Vulkan loader linked directly with the application.</p>
+<h3><a class="anchor" id="compile_options_win32"></a>
+Windows specific CMake options</h3>
+<p><a class="anchor" id="USE_MSVC_RUNTIME_LIBRARY_DLL"></a><b>USE_MSVC_RUNTIME_LIBRARY_DLL</b> determines whether to use the DLL version or the static library version of the Visual C++ runtime library. If set to <code>ON</code>, the DLL version of the Visual C++ library is used.</p>
+<p><a class="anchor" id="GLFW_USE_HYBRID_HPG"></a><b>GLFW_USE_HYBRID_HPG</b> determines whether to export the <code>NvOptimusEnablement</code> and <code>AmdPowerXpressRequestHighPerformance</code> symbols, which force the use of the high-performance GPU on Nvidia Optimus and AMD PowerXpress systems. These symbols need to be exported by the EXE to be detected by the driver, so the override will not work if GLFW is built as a DLL.</p>
+<h1><a class="anchor" id="compile_manual"></a>
+Compiling GLFW manually</h1>
+<p>If you wish to compile GLFW without its CMake build environment then you will have to do at least some of the platform detection yourself. GLFW needs a configuration macro to be defined in order to know what window system it's being compiled for and also has optional, platform-specific ones for various features.</p>
+<p>When building with CMake, the <code>glfw_config.h</code> configuration header is generated based on the current platform and CMake options. The GLFW CMake environment defines <b>GLFW_USE_CONFIG_H</b>, which causes this header to be included by <code>internal.h</code>. Without this macro, GLFW will expect the necessary configuration macros to be defined on the command-line.</p>
+<p>The window creation API is used to create windows, handle input, monitors, gamma ramps and clipboard. The options are:</p>
+<ul>
+<li><b>_GLFW_COCOA</b> to use the Cocoa frameworks</li>
+<li><b>_GLFW_WIN32</b> to use the Win32 API</li>
+<li><b>_GLFW_X11</b> to use the X Window System</li>
+<li><b>_GLFW_WAYLAND</b> to use the Wayland API (experimental and incomplete)</li>
+<li><b>_GLFW_OSMESA</b> to use the OSMesa API (headless and non-interactive)</li>
+</ul>
+<p>If you are building GLFW as a shared library / dynamic library / DLL then you must also define <b>_GLFW_BUILD_DLL</b>. Otherwise, you must not define it.</p>
+<p>If you are linking the Vulkan loader directly with your application then you must also define <b>_GLFW_VULKAN_STATIC</b>. Otherwise, GLFW will attempt to use the external version.</p>
+<p>If you are using a custom name for the Vulkan, EGL, GLX, OSMesa, OpenGL, GLESv1 or GLESv2 library, you can override the default names by defining those you need of <b>_GLFW_VULKAN_LIBRARY</b>, <b>_GLFW_EGL_LIBRARY</b>, <b>_GLFW_GLX_LIBRARY</b>, <b>_GLFW_OSMESA_LIBRARY</b>, <b>_GLFW_OPENGL_LIBRARY</b>, <b>_GLFW_GLESV1_LIBRARY</b> and <b>_GLFW_GLESV2_LIBRARY</b>. Otherwise, GLFW will use the built-in default names.</p>
+<p>For the EGL context creation API, the following options are available:</p>
+<ul>
+<li><b>_GLFW_USE_EGLPLATFORM_H</b> to use an existing <code>EGL/eglplatform.h</code> header file for native handle types (fallback)</li>
+</ul>
+<dl class="section note"><dt>Note</dt><dd>None of the <a class="el" href="build_guide.html#build_macros">GLFW header option macros</a> may be defined during the compilation of GLFW. If you define any of these in your build files, make sure they are not applied to the GLFW sources. </dd></dl>

+Context objects</h1>
+<p>A window object encapsulates both a top-level window and an OpenGL or OpenGL ES context. It is created with <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> and destroyed with <a class="el" href="group__window.html#gacdf43e51376051d2c091662e9fe3d7b2">glfwDestroyWindow</a> or <a class="el" href="group__init.html#gaaae48c0a18607ea4a4ba951d939f0901">glfwTerminate</a>. See <a class="el" href="window_guide.html#window_creation">Window creation</a> for more information.</p>
+<p>As the window and context are inseparably linked, the window object also serves as the context handle.</p>
+<p>To test the creation of various kinds of contexts and see their properties, run the <code>glfwinfo</code> test program.</p>
+<dl class="section note"><dt>Note</dt><dd>Vulkan does not have a context and the Vulkan instance is created via the Vulkan API itself. If you will be using Vulkan to render to a window, disable context creation by setting the <a class="el" href="window_guide.html#GLFW_CLIENT_API_hint">GLFW_CLIENT_API</a> hint to <code>GLFW_NO_API</code>. For more information, see the <a class="el" href="vulkan_guide.html">Vulkan guide</a>.</dd></dl>
+<h2><a class="anchor" id="context_hints"></a>

+OpenGL and OpenGL ES extensions</h1>
+<p>One of the benefits of OpenGL and OpenGL ES is their extensibility. Hardware vendors may include extensions in their implementations that extend the API before that functionality is included in a new version of the OpenGL or OpenGL ES specification, and some extensions are never included and remain as extensions until they become obsolete.</p>
+<p>An extension is defined by:</p>
+<ul>
+<li>An extension name (e.g. <code>GL_ARB_debug_output</code>)</li>
+<li>New OpenGL tokens (e.g. <code>GL_DEBUG_SEVERITY_HIGH_ARB</code>)</li>
+<li>New OpenGL functions (e.g. <code>glGetDebugMessageLogARB</code>)</li>
+</ul>
+<p>Note the <code>ARB</code> affix, which stands for Architecture Review Board and is used for official extensions. The extension above was created by the ARB, but there are many different affixes, like <code>NV</code> for Nvidia and <code>AMD</code> for, well, AMD. Any group may also use the generic <code>EXT</code> affix. Lists of extensions, together with their specifications, can be found at the <a href="https://www.opengl.org/registry/">OpenGL Registry</a> and <a href="https://www.khronos.org/registry/gles/">OpenGL ES Registry</a>.</p>
+<h2><a class="anchor" id="context_glext_auto"></a>
+Loading extension with a loader library</h2>
+<p>An extension loader library is the easiest and best way to access both OpenGL and OpenGL ES extensions and modern versions of the core OpenGL or OpenGL ES APIs. They will take care of all the details of declaring and loading everything you need. One such library is <a href="https://github.com/Dav1dde/glad">glad</a> and there are several others.</p>
+<p>The following example will use glad but all extension loader libraries work similarly.</p>
+<p>First you need to generate the source files using the glad Python script. This example generates a loader for any version of OpenGL, which is the default for both GLFW and glad, but loaders for OpenGL ES, as well as loaders for specific API versions and extension sets can be generated. The generated files are written to the <code>output</code> directory.</p>
+<div class="fragment"><div class="line">python main.py --generator c --no-loader --out-path output</div>
+</div><!-- fragment --><p>The <code>--no-loader</code> option is added because GLFW already provides a function for loading OpenGL and OpenGL ES function pointers, one that automatically uses the selected context creation API, and glad can call this instead of having to implement its own. There are several other command-line options as well. See the glad documentation for details.</p>
+<p>Add the generated <code>output/src/glad.c</code>, <code>output/include/glad/glad.h</code> and <code>output/include/KHR/khrplatform.h</code> files to your build. Then you need to include the glad header file, which will replace the OpenGL header of your development environment. By including the glad header before the GLFW header, it suppresses the development environment's OpenGL or OpenGL ES header.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#include &lt;glad/glad.h&gt;</span></div>
+<div class="line"><span class="preprocessor">#include &lt;<a class="code" href="glfw3_8h.html">GLFW/glfw3.h</a>&gt;</span></div>
+</div><!-- fragment --><p>Finally you need to initialize glad once you have a suitable current context.</p>
+<div class="fragment"><div class="line">window = <a class="code" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>(640, 480, <span class="stringliteral">&quot;My Window&quot;</span>, NULL, NULL);</div>

+Loading extensions manually</h2>
+<p><b>Do not use this technique</b> unless it is absolutely necessary. An <a class="el" href="context_guide.html#context_glext_auto">extension loader library</a> will save you a ton of tedious, repetitive, error prone work.</p>
+<p>To use a certain extension, you must first check whether the context supports that extension and then, if it introduces new functions, retrieve the pointers to those functions. GLFW provides <a class="el" href="group__context.html#ga87425065c011cef1ebd6aac75e059dfa">glfwExtensionSupported</a> and <a class="el" href="group__context.html#ga35f1837e6f666781842483937612f163">glfwGetProcAddress</a> for manual loading of extensions and new API functions.</p>
+<p>This section will demonstrate manual loading of OpenGL extensions. The loading of OpenGL ES extensions is identical except for the name of the extension header.</p>
+<h3><a class="anchor" id="context_glext_header"></a>
+The glext.h header</h3>
+<p>The <code>glext.h</code> extension header is a continually updated file that defines the interfaces for all OpenGL extensions. The latest version of this can always be found at the <a href="https://www.opengl.org/registry/">OpenGL Registry</a>. There are also extension headers for the various versions of OpenGL ES at the <a href="https://www.khronos.org/registry/gles/">OpenGL ES Registry</a>. It it strongly recommended that you use your own copy of the extension header, as the one included in your development environment may be several years out of date and may not include the extensions you wish to use.</p>
+<p>The header defines function pointer types for all functions of all extensions it supports. These have names like <code>PFNGLGETDEBUGMESSAGELOGARBPROC</code> (for <code>glGetDebugMessageLogARB</code>), i.e. the name is made uppercase and <code>PFN</code> (pointer to function) and <code>PROC</code> (procedure) are added to the ends.</p>
+<p>To include the extension header, define <a class="el" href="build_guide.html#GLFW_INCLUDE_GLEXT">GLFW_INCLUDE_GLEXT</a> before including the GLFW header.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#define GLFW_INCLUDE_GLEXT</span></div>
+<div class="line"><span class="preprocessor">#include &lt;GLFW/glfw3.h&gt;</span></div>
+</div><!-- fragment --><h3><a class="anchor" id="context_glext_string"></a>
+Checking for extensions</h3>
+<p>A given machine may not actually support the extension (it may have older drivers or a graphics card that lacks the necessary hardware features), so it is necessary to check at run-time whether the context supports the extension. This is done with <a class="el" href="group__context.html#ga87425065c011cef1ebd6aac75e059dfa">glfwExtensionSupported</a>.</p>
+<div class="fragment"><div class="line"><span class="keywordflow">if</span> (<a class="code" href="group__context.html#ga87425065c011cef1ebd6aac75e059dfa">glfwExtensionSupported</a>(<span class="stringliteral">&quot;GL_ARB_debug_output&quot;</span>))</div>
+<div class="line">{</div>
+<div class="line">    <span class="comment">// The extension is supported by the current context</span></div>
+<div class="line">}</div>
+</div><!-- fragment --><p>The argument is a null terminated ASCII string with the extension name. If the extension is supported, <a class="el" href="group__context.html#ga87425065c011cef1ebd6aac75e059dfa">glfwExtensionSupported</a> returns <code>GLFW_TRUE</code>, otherwise it returns <code>GLFW_FALSE</code>.</p>
+<h3><a class="anchor" id="context_glext_proc"></a>
+Fetching function pointers</h3>
+<p>Many extensions, though not all, require the use of new OpenGL functions. These functions often do not have entry points in the client API libraries of your operating system, making it necessary to fetch them at run time. You can retrieve pointers to these functions with <a class="el" href="group__context.html#ga35f1837e6f666781842483937612f163">glfwGetProcAddress</a>.</p>
+<div class="fragment"><div class="line">PFNGLGETDEBUGMESSAGELOGARBPROC pfnGetDebugMessageLog = <a class="code" href="group__context.html#ga35f1837e6f666781842483937612f163">glfwGetProcAddress</a>(<span class="stringliteral">&quot;glGetDebugMessageLogARB&quot;</span>);</div>
+</div><!-- fragment --><p>In general, you should avoid giving the function pointer variables the (exact) same name as the function, as this may confuse your linker. Instead, you can use a different prefix, like above, or some other naming scheme.</p>

+<p>This function sets the key callback of the specified window, which is called when a key is pressed, repeated or released.</p>

+<p>See <a class="el" href="input_guide.html#input_key">key input</a> for how these are used.</p>
+<p>These key codes are inspired by the <em>USB HID Usage Tables v1.12</em> (p. 53-60), but re-arranged to map to 7-bit ASCII for printable keys (function keys are put in the 256+ range).</p>
+<p>The naming of the key codes follow these rules:</p><ul>
+<li>The US keyboard layout is used</li>
+<li>Names of printable alpha-numeric characters are used (e.g. "A", "R", "3", etc.)</li>
+<li>For non-alphanumeric characters, Unicode:ish names are used (e.g. "COMMA", "LEFT_SQUARE_BRACKET", etc.). Note that some names do not correspond to the Unicode standard (usually for brevity)</li>
+<li>Keys that lack a clear US mapping are named "WORLD_x"</li>
+<li>For non-printable keys, custom names are used (e.g. "F4", "BACKSPACE", etc.) </li>
+</ul>

+<p><b>By using the native access functions you assert that you know what you're doing and how to fix problems caused by using them. If you don't, you shouldn't be using them.</b></p>
+<p>Before the inclusion of <a class="el" href="glfw3native_8h.html">glfw3native.h</a>, you may define zero or more window system API macro and zero or more context creation API macros.</p>
+<p>The chosen backends must match those the library was compiled for. Failure to do this will cause a link-time error.</p>
+<p>The available window API macros are:</p><ul>
+<li><code>GLFW_EXPOSE_NATIVE_WIN32</code></li>
+<li><code>GLFW_EXPOSE_NATIVE_COCOA</code></li>
+<li><code>GLFW_EXPOSE_NATIVE_X11</code></li>
+<li><code>GLFW_EXPOSE_NATIVE_WAYLAND</code></li>
+</ul>
+<p>The available context API macros are:</p><ul>
+<li><code>GLFW_EXPOSE_NATIVE_WGL</code></li>
+<li><code>GLFW_EXPOSE_NATIVE_NSGL</code></li>
+<li><code>GLFW_EXPOSE_NATIVE_GLX</code></li>
+<li><code>GLFW_EXPOSE_NATIVE_EGL</code></li>
+<li><code>GLFW_EXPOSE_NATIVE_OSMESA</code></li>
+</ul>
+<p>These macros select which of the native access functions that are declared and which platform-specific headers to include. It is then up your (by definition platform-specific) code to handle which of these should be defined. </p>

+<p>This function creates a window and its associated OpenGL or OpenGL ES context. Most of the options controlling how the window and its context should be created are specified with <a class="el" href="window_guide.html#window_hints">window hints</a>.</p>
+<p>Successful creation does not change which context is current. Before you can use the newly created context, you need to <a class="el" href="context_guide.html#context_current">make it current</a>. For information about the <code>share</code> parameter, see <a class="el" href="context_guide.html#context_sharing">Context object sharing</a>.</p>
+<p>The created window, framebuffer and context may differ from what you requested, as not all parameters and hints are <a class="el" href="window_guide.html#window_hints_hard">hard constraints</a>. This includes the size of the window, especially for full screen windows. To query the actual attributes of the created window, framebuffer and context, see <a class="el" href="group__window.html#gacccb29947ea4b16860ebef42c2cb9337">glfwGetWindowAttrib</a>, <a class="el" href="group__window.html#gaeea7cbc03373a41fb51cfbf9f2a5d4c6">glfwGetWindowSize</a> and <a class="el" href="group__window.html#ga0e2637a4161afb283f5300c7f94785c9">glfwGetFramebufferSize</a>.</p>
+<p>To create a full screen window, you need to specify the monitor the window will cover. If no monitor is specified, the window will be windowed mode. Unless you have a way for the user to choose a specific monitor, it is recommended that you pick the primary monitor. For more information on how to query connected monitors, see <a class="el" href="monitor_guide.html#monitor_monitors">Retrieving monitors</a>.</p>
+<p>For full screen windows, the specified size becomes the resolution of the window's <em>desired video mode</em>. As long as a full screen window is not iconified, the supported video mode most closely matching the desired video mode is set for the specified monitor. For more information about full screen windows, including the creation of so called <em>windowed full screen</em> or <em>borderless full screen</em> windows, see <a class="el" href="window_guide.html#window_windowed_full_screen">"Windowed full screen" windows</a>.</p>
+<p>Once you have created the window, you can switch it between windowed and full screen mode with <a class="el" href="group__window.html#ga81c76c418af80a1cce7055bccb0ae0a7">glfwSetWindowMonitor</a>. This will not affect its OpenGL or OpenGL ES context.</p>
+<p>By default, newly created windows use the placement recommended by the window system. To create the window at a specific position, make it initially invisible using the <a class="el" href="window_guide.html#GLFW_VISIBLE_hint">GLFW_VISIBLE</a> window hint, set its <a class="el" href="window_guide.html#window_pos">position</a> and then <a class="el" href="window_guide.html#window_hide">show</a> it.</p>
+<p>As long as at least one full screen window is not iconified, the screensaver is prohibited from starting.</p>
+<p>Window systems put limits on window sizes. Very large or very small window dimensions may be overridden by the window system on creation. Check the actual <a class="el" href="window_guide.html#window_size">size</a> after creation.</p>
+<p>The <a class="el" href="window_guide.html#buffer_swap">swap interval</a> is not set during window creation and the initial value may vary depending on driver settings and defaults.</p>

+<dl class="section remark"><dt>Remarks</dt><dd><b>Windows:</b> Window creation will fail if the Microsoft GDI software OpenGL implementation is the only one available.</dd>
+<dd>
+<b>Windows:</b> If the executable has an icon resource named <code>GLFW_ICON,</code> it will be set as the initial icon for the window. If no such icon is present, the <code>IDI_APPLICATION</code> icon will be used instead. To set a different icon, see <a class="el" href="group__window.html#gadd7ccd39fe7a7d1f0904666ae5932dc5">glfwSetWindowIcon</a>.</dd>
+<dd>
+<b>Windows:</b> The context to share resources with must not be current on any other thread.</dd>
+<dd>
+<b>macOS:</b> The OS only supports forward-compatible core profile contexts for OpenGL versions 3.2 and later. Before creating an OpenGL context of version 3.2 or later you must set the <a class="el" href="window_guide.html#GLFW_OPENGL_FORWARD_COMPAT_hint">GLFW_OPENGL_FORWARD_COMPAT</a> and <a class="el" href="window_guide.html#GLFW_OPENGL_PROFILE_hint">GLFW_OPENGL_PROFILE</a> hints accordingly. OpenGL 3.0 and 3.1 contexts are not supported at all on macOS.</dd>
+<dd>
+<b>macOS:</b> The GLFW window has no icon, as it is not a document window, but the dock icon will be the same as the application bundle's icon. For more information on bundles, see the <a href="https://developer.apple.com/library/mac/documentation/CoreFoundation/Conceptual/CFBundles/">Bundle Programming Guide</a> in the Mac Developer Library.</dd>
+<dd>
+<b>macOS:</b> The first time a window is created the menu bar is created. If GLFW finds a <code>MainMenu.nib</code> it is loaded and assumed to contain a menu bar. Otherwise a minimal menu bar is created manually with common commands like Hide, Quit and About. The About entry opens a minimal about dialog with information from the application's bundle. Menu bar creation can be disabled entirely with the <a class="el" href="group__init.html#ga71e0b4ce2f2696a84a9b8c5e12dc70cf">GLFW_COCOA_MENUBAR</a> init hint.</dd>
+<dd>
+<b>macOS:</b> On OS X 10.10 and later the window frame will not be rendered at full resolution on Retina displays unless the <a class="el" href="window_guide.html#GLFW_COCOA_RETINA_FRAMEBUFFER_hint">GLFW_COCOA_RETINA_FRAMEBUFFER</a> hint is <code>GLFW_TRUE</code> and the <code>NSHighResolutionCapable</code> key is enabled in the application bundle's <code>Info.plist</code>. For more information, see <a href="https://developer.apple.com/library/mac/documentation/GraphicsAnimation/Conceptual/HighResolutionOSX/Explained/Explained.html">High Resolution Guidelines for OS X</a> in the Mac Developer Library. The GLFW test and example programs use a custom <code>Info.plist</code> template for this, which can be found as <code>CMake/MacOSXBundleInfo.plist.in</code> in the source tree.</dd>
+<dd>
+<b>macOS:</b> When activating frame autosaving with <a class="el" href="window_guide.html#GLFW_COCOA_FRAME_NAME_hint">GLFW_COCOA_FRAME_NAME</a>, the specified window size and position may be overridden by previously saved values.</dd>
+<dd>
+<b>X11:</b> Some window managers will not respect the placement of initially hidden windows.</dd>
+<dd>
+<b>X11:</b> Due to the asynchronous nature of X11, it may take a moment for a window to reach its requested state. This means you may not be able to query the final size, position or other attributes directly after window creation.</dd>
+<dd>
+<b>X11:</b> The class part of the <code>WM_CLASS</code> window property will by default be set to the window title passed to this function. The instance part will use the contents of the <code>RESOURCE_NAME</code> environment variable, if present and not empty, or fall back to the window title. Set the <a class="el" href="window_guide.html#GLFW_X11_CLASS_NAME_hint">GLFW_X11_CLASS_NAME</a> and <a class="el" href="window_guide.html#GLFW_X11_INSTANCE_NAME_hint">GLFW_X11_INSTANCE_NAME</a> window hints to override this.</dd>
+<dd>
+<b>Wayland:</b> Compositors should implement the xdg-decoration protocol for GLFW to decorate the window properly. If this protocol isn't supported, or if the compositor prefers client-side decorations, a very simple fallback frame will be drawn using the wp_viewporter protocol. A compositor can still emit close, maximize or fullscreen events, using for instance a keybind mechanism. If neither of these protocols is supported, the window won't be decorated.</dd>
+<dd>
+<b>Wayland:</b> A full screen window will not attempt to change the mode, no matter what the requested size or refresh rate.</dd>
+<dd>
+<b>Wayland:</b> Screensaver inhibition requires the idle-inhibit protocol to be implemented in the user's compositor.</dd></dl>

+<p>This function processes only those events that are already in the event queue and then returns immediately. Processing events will cause the window and input callbacks associated with those events to be called.</p>
+<p>On some platforms, a window move, resize or menu operation will cause event processing to block. This is due to how event processing is designed on those platforms. You can use the <a class="el" href="window_guide.html#window_refresh">window refresh callback</a> to redraw the contents of your window when necessary during such operations.</p>
+<p>Do not assume that callbacks you set will <em>only</em> be called in response to event processing functions like this one. While it is necessary to poll for events, window systems that require GLFW to register callbacks of its own can pass events to GLFW in response to many window system function calls.

+Introduction</h1>
+<p>GLFW is a free, Open Source, multi-platform library for OpenGL, OpenGL ES and Vulkan application development. It provides a simple, platform-independent API for creating windows, contexts and surfaces, reading input, handling events, etc.</p>
+<p><a class="el" href="news.html#news_33">Release notes for version 3.3</a> list new features, caveats and deprecations.</p>
+<p><a class="el" href="quick_guide.html">Getting started</a> is a guide for users new to GLFW. It takes you through how to write a small but complete program.</p>
+<p>There are guides for each section of the API:</p>
+<ul>
+<li><a class="el" href="intro_guide.html">Introduction to the API</a> – initialization, error handling and high-level design</li>
+<li><a class="el" href="window_guide.html">Window guide</a> – creating and working with windows and framebuffers</li>
+<li><a class="el" href="context_guide.html">Context guide</a> – working with OpenGL and OpenGL ES contexts</li>
+<li><a class="el" href="vulkan_guide.html">Vulkan guide</a> - working with Vulkan objects and extensions</li>
+<li><a class="el" href="monitor_guide.html">Monitor guide</a> – enumerating and working with monitors and video modes</li>
+<li><a class="el" href="input_guide.html">Input guide</a> – receiving events, polling and processing input</li>
+</ul>
+<p>Once you have written a program, see <a class="el" href="compile_guide.html">Compiling GLFW</a> and <a class="el" href="build_guide.html">Building applications</a>.</p>
+<p>The <a href="modules.html">reference documentation</a> provides more detailed information about specific functions.</p>
+<p><a class="el" href="moving_guide.html">Moving from GLFW 2 to 3</a> explains what has changed and how to update existing code to use the new API.</p>
+<p>There is a section on <a class="el" href="intro_guide.html#guarantees_limitations">Guarantees and limitations</a> for pointer lifetimes, reentrancy, thread safety, event order and backward and forward compatibility.</p>
+<p>The <a href="https://www.glfw.org/faq.html">FAQ</a> answers many common questions about the design, implementation and use of GLFW.</p>
+<p>Finally, <a class="el" href="compat_guide.html">Standards conformance</a> explains what APIs, standards and protocols GLFW uses and what happens when they are not present on a given machine.</p>
+<p>This documentation was generated with Doxygen. The sources for it are available in both the <a href="https://www.glfw.org/download.html">source distribution</a> and <a href="https://github.com/glfw/glfw">GitHub repository</a>. </p>

+<p>GLFW provides many kinds of input. While some can only be polled, like time, or only received via callbacks, like scrolling, many provide both callbacks and polling. Callbacks are more work to use than polling but is less CPU intensive and guarantees that you do not miss state changes.</p>
+<p>All input callbacks receive a window handle. By using the <a class="el" href="window_guide.html#window_userptr">window user pointer</a>, you can access non-global structures or objects from your callbacks.</p>
+<p>To get a better feel for how the various events callbacks behave, run the <code>events</code> test program. It register every callback supported by GLFW and prints out all arguments provided for every event, along with time and sequence information.</p>
+<h1><a class="anchor" id="events"></a>
+Event processing</h1>
+<p>GLFW needs to poll the window system for events both to provide input to the application and to prove to the window system that the application hasn't locked up. Event processing is normally done each frame after <a class="el" href="window_guide.html#buffer_swap">buffer swapping</a>. Even when you have no windows, event polling needs to be done in order to receive monitor and joystick connection events.</p>
+<p>There are three functions for processing pending events. <a class="el" href="group__window.html#ga37bd57223967b4211d60ca1a0bf3c832">glfwPollEvents</a>, processes only those events that have already been received and then returns immediately.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga37bd57223967b4211d60ca1a0bf3c832">glfwPollEvents</a>();</div>
+</div><!-- fragment --><p>This is the best choice when rendering continuously, like most games do.</p>
+<p>If you only need to update the contents of the window when you receive new input, <a class="el" href="group__window.html#ga554e37d781f0a997656c26b2c56c835e">glfwWaitEvents</a> is a better choice.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga554e37d781f0a997656c26b2c56c835e">glfwWaitEvents</a>();</div>
+</div><!-- fragment --><p>It puts the thread to sleep until at least one event has been received and then processes all received events. This saves a great deal of CPU cycles and is useful for, for example, editing tools.</p>
+<p>If you want to wait for events but have UI elements or other tasks that need periodic updates, <a class="el" href="group__window.html#ga605a178db92f1a7f1a925563ef3ea2cf">glfwWaitEventsTimeout</a> lets you specify a timeout.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga605a178db92f1a7f1a925563ef3ea2cf">glfwWaitEventsTimeout</a>(0.7);</div>
+</div><!-- fragment --><p>It puts the thread to sleep until at least one event has been received, or until the specified number of seconds have elapsed. It then processes any received events.</p>
+<p>If the main thread is sleeping in <a class="el" href="group__window.html#ga554e37d781f0a997656c26b2c56c835e">glfwWaitEvents</a>, you can wake it from another thread by posting an empty event to the event queue with <a class="el" href="group__window.html#gab5997a25187e9fd5c6f2ecbbc8dfd7e9">glfwPostEmptyEvent</a>.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#gab5997a25187e9fd5c6f2ecbbc8dfd7e9">glfwPostEmptyEvent</a>();</div>
+</div><!-- fragment --><p>Do not assume that callbacks will <em>only</em> be called in response to the above functions. While it is necessary to process events in one or more of the ways above, window systems that require GLFW to register callbacks of its own can pass events to GLFW in response to many window system function calls. GLFW will pass those events on to the application callbacks before returning.</p>
+<p>For example, on Windows the system function that <a class="el" href="group__window.html#ga371911f12c74c504dd8d47d832d095cb">glfwSetWindowSize</a> is implemented with will send window size events directly to the event callback that every window has and that GLFW implements for its windows. If you have set a <a class="el" href="window_guide.html#window_size">window size callback</a> GLFW will call it in turn with the new size before everything returns back out of the <a class="el" href="group__window.html#ga371911f12c74c504dd8d47d832d095cb">glfwSetWindowSize</a> call.</p>
+<h1><a class="anchor" id="input_keyboard"></a>
+Keyboard input</h1>
+<p>GLFW divides keyboard input into two categories; key events and character events. Key events relate to actual physical keyboard keys, whereas character events relate to the Unicode code points generated by pressing some of them.</p>
+<p>Keys and characters do not map 1:1. A single key press may produce several characters, and a single character may require several keys to produce. This may not be the case on your machine, but your users are likely not all using the same keyboard layout, input method or even operating system as you.</p>
+<h2><a class="anchor" id="input_key"></a>
+Key input</h2>
+<p>If you wish to be notified when a physical key is pressed or released or when it repeats, set a key callback.</p>

+<p>GLFW supports text input in the form of a stream of <a href="https://en.wikipedia.org/wiki/Unicode">Unicode code points</a>, as produced by the operating system text input system. Unlike key input, text input obeys keyboard layouts and modifier keys and supports composing characters using <a href="https://en.wikipedia.org/wiki/Dead_key">dead keys</a>. Once received, you can encode the code points into UTF-8 or any other encoding you prefer.</p>
+<p>Because an <code>unsigned int</code> is 32 bits long on all platforms supported by GLFW, you can treat the code point argument as native endian UTF-32.</p>
+<p>If you wish to offer regular text input, set a character callback.</p>

+Gamepad input</h2>
+<p>The joystick functions provide unlabeled axes, buttons and hats, with no indication of where they are located on the device. Their order may also vary between platforms even with the same device.</p>
+<p>To solve this problem the SDL community crowdsourced the <a href="https://github.com/gabomdq/SDL_GameControllerDB">SDL_GameControllerDB</a> project, a database of mappings from many different devices to an Xbox-like gamepad.</p>
+<p>GLFW supports this mapping format and contains a copy of the mappings available at the time of release. See <a class="el" href="input_guide.html#gamepad_mapping">Gamepad mappings</a> for how to update this at runtime. Mappings will be assigned to joysticks automatically any time a joystick is connected or the mappings are updated.</p>

+</div><!-- fragment --><p>This function supports everything from single lines up to and including the unmodified contents of the whole <code>gamecontrollerdb.txt</code> file.</p>
+<p>Below is a description of the mapping format. Please keep in mind that <b>this description is not authoritative</b>. The format is defined by the SDL and SDL_GameControllerDB projects and their documentation and code takes precedence.</p>
+<p>Each mapping is a single line of comma-separated values describing the GUID, name and layout of the gamepad. Lines that do not begin with a hexadecimal digit are ignored.</p>
+<p>The first value is always the gamepad GUID, a 32 character long hexadecimal string that typically identifies its make, model, revision and the type of connection to the computer. When this information is not available, the GUID is generated using the gamepad name. GLFW uses the SDL 2.0.5+ GUID format but can convert from the older formats.</p>
+<p>The second value is always the human-readable name of the gamepad.</p>
+<p>All subsequent values are in the form <code>&lt;field&gt;:&lt;value&gt;</code> and describe the layout of the mapping. These fields may not all be present and may occur in any order.</p>
+<p>The button fields are <code>a</code>, <code>b</code>, <code>c</code>, <code>d</code>, <code>back</code>, <code>start</code>, <code>guide</code>, <code>dpup</code>, <code>dpright</code>, <code>dpdown</code>, <code>dpleft</code>, <code>leftshoulder</code>, <code>rightshoulder</code>, <code>leftstick</code> and <code>rightstick</code>.</p>
+<p>The axis fields are <code>leftx</code>, <code>lefty</code>, <code>rightx</code>, <code>righty</code>, <code>lefttrigger</code> and <code>righttrigger</code>.</p>
+<p>The value of an axis or button field can be a joystick button, a joystick axis, a hat bitmask or empty. Joystick buttons are specified as <code>bN</code>, for example <code>b2</code> for the third button. Joystick axes are specified as <code>aN</code>, for example <code>a7</code> for the eighth button. Joystick hat bit masks are specified as <code>hN.N</code>, for example <code>h0.8</code> for left on the first hat. More than one bit may be set in the mask.</p>
+<p>Before an axis there may be a <code>+</code> or <code>-</code> range modifier, for example <code>+a3</code> for the positive half of the fourth axis. This restricts input to only the positive or negative halves of the joystick axis. After an axis or half-axis there may be the <code>~</code> inversion modifier, for example <code>a2~</code> or <code>-a7~</code>. This negates the values of the gamepad axis.</p>
+<p>The hat bit mask match the <a class="el" href="group__hat__state.html">hat states</a> in the joystick functions.</p>
+<p>There is also the special <code>platform</code> field that specifies which platform the mapping is valid for. Possible values are <code>Windows</code>, <code>Mac OS X</code> and <code>Linux</code>.</p>
+<p>Below is an example of what a gamepad mapping might look like. It is the one built into GLFW for Xbox controllers accessed via the XInput API on Windows. This example has been broken into several lines to fit on the page, but real gamepad mappings must be a single line.</p>

+</div>
+<div class="textblock"><p>There are several interfaces inside GLFW. Each interface has its own area of responsibility and its own naming conventions.</p>
+<h1><a class="anchor" id="internals_public"></a>
+Public interface</h1>
+<p>The most well-known is the public interface, described in the <a class="el" href="glfw3_8h.html" title="The header of the GLFW 3 API.">glfw3.h</a> header file. This is implemented in source files shared by all platforms and these files contain no platform-specific code. This code usually ends up calling the platform and internal interfaces to do the actual work.</p>
+<p>The public interface uses the OpenGL naming conventions except with GLFW and glfw instead of GL and gl. For struct members, where OpenGL sets no precedent, it use headless camel case.</p>
+<p>Examples: <code>glfwCreateWindow</code>, <code>GLFWwindow</code>, <code>GLFW_RED_BITS</code></p>
+<h1><a class="anchor" id="internals_native"></a>
+Native interface</h1>
+<p>The <a class="el" href="group__native.html">native interface</a> is a small set of publicly available but platform-specific functions, described in the <a class="el" href="glfw3native_8h.html" title="The header of the native access functions.">glfw3native.h</a> header file and used to gain access to the underlying window, context and (on some platforms) display handles used by the platform interface.</p>
+<p>The function names of the native interface are similar to those of the public interface, but embeds the name of the interface that the returned handle is from.</p>
+<p>Examples: <code>glfwGetX11Window</code>, <code>glfwGetWGLContext</code></p>
+<h1><a class="anchor" id="internals_internal"></a>
+Internal interface</h1>
+<p>The internal interface consists of utility functions used by all other interfaces. It is shared code implemented in the same shared source files as the public and event interfaces. The internal interface is described in the internal.h header file.</p>
+<p>The internal interface is in charge of GLFW's global data, which it stores in a <code>_GLFWlibrary</code> struct named <code>_glfw</code>.</p>
+<p>The internal interface uses the same style as the public interface, except all global names have a leading underscore.</p>
+<p>Examples: <code>_glfwIsValidContextConfig</code>, <code>_GLFWwindow</code>, <code>_glfw.monitorCount</code></p>
+<h1><a class="anchor" id="internals_platform"></a>
+Platform interface</h1>
+<p>The platform interface implements all platform-specific operations as a service to the public interface. This includes event processing. The platform interface is never directly called by application code and never directly calls application-provided callbacks. It is also prohibited from modifying the platform-independent part of the internal structs. Instead, it calls the event interface when events interesting to GLFW are received.</p>
+<p>The platform interface mirrors those parts of the public interface that needs to perform platform-specific operations on some or all platforms. The are also named the same except that the glfw function prefix is replaced by _glfwPlatform.</p>
+<p>Examples: <code>_glfwPlatformCreateWindow</code></p>
+<p>The platform interface also defines structs that contain platform-specific global and per-object state. Their names mirror those of the internal interface, except that an interface-specific suffix is added.</p>
+<p>Examples: <code>_GLFWwindowX11</code>, <code>_GLFWcontextWGL</code></p>
+<p>These structs are incorporated as members into the internal interface structs using special macros that name them after the specific interface used. This prevents shared code from accidentally using these members.</p>
+<p>Examples: <code>window-&gt;win32.handle</code>, <code>_glfw.x11.display</code></p>
+<h1><a class="anchor" id="internals_event"></a>
+Event interface</h1>
+<p>The event interface is implemented in the same shared source files as the public interface and is responsible for delivering the events it receives to the application, either via callbacks, via window state changes or both.</p>
+<p>The function names of the event interface use a <code>_glfwInput</code> prefix and the ObjectEvent pattern.</p>
+<p>Examples: <code>_glfwInputWindowFocus</code>, <code>_glfwInputCursorPos</code></p>
+<h1><a class="anchor" id="internals_static"></a>
+Static functions</h1>
+<p>Static functions may be used by any interface and have no prefixes or suffixes. These use headless camel case.</p>
+<p>Examples: <code>isValidElementForJoystick</code></p>
+<h1><a class="anchor" id="internals_config"></a>
+Configuration macros</h1>
+<p>GLFW uses a number of configuration macros to select at compile time which interfaces and code paths to use. They are defined in the glfw_config.h header file, which is generated from the <code>glfw_config.h.in</code> file by CMake.</p>
+<p>Configuration macros the same style as tokens in the public interface, except with a leading underscore.</p>
+<p>Examples: <code>_GLFW_WIN32</code>, <code>_GLFW_BUILD_DLL</code> </p>

+Error handling</h1>
+<p>Some GLFW functions have return values that indicate an error, but this is often not very helpful when trying to figure out what happened or why it occurred.

+<p>Do not rely on a currently invalid call to generate a specific error, as in the future that same call may generate a different error or become valid.</p>
+<h1><a class="anchor" id="coordinate_systems"></a>
+Coordinate systems</h1>
+<p>GLFW has two primary coordinate systems: the <em>virtual screen</em> and the window <em>content area</em> or <em>content area</em>. Both use the same unit: <em>virtual screen coordinates</em>, or just <em>screen coordinates</em>, which don't necessarily correspond to pixels.</p>
+<p><img src="spaces.svg" alt="" width="90%" class="inline"/></p>
+<p>Both the virtual screen and the content area coordinate systems have the X-axis pointing to the right and the Y-axis pointing down.</p>
+<p>Window and monitor positions are specified as the position of the upper-left corners of their content areas relative to the virtual screen, while cursor positions are specified relative to a window's content area.</p>
+<p>Because the origin of the window's content area coordinate system is also the point from which the window position is specified, you can translate content area coordinates to the virtual screen by adding the window position. The window frame, when present, extends out from the content area but does not affect the window position.</p>
+<p>Almost all positions and sizes in GLFW are measured in screen coordinates relative to one of the two origins above. This includes cursor positions, window positions and sizes, window frame sizes, monitor positions and video mode resolutions.</p>
+<p>Two exceptions are the <a class="el" href="monitor_guide.html#monitor_size">monitor physical size</a>, which is measured in millimetres, and <a class="el" href="window_guide.html#window_fbsize">framebuffer size</a>, which is measured in pixels.</p>
+<p>Pixels and screen coordinates may map 1:1 on your machine, but they won't on every other machine, for example on a Mac with a Retina display. The ratio between screen coordinates and pixels may also change at run-time depending on which monitor the window is currently considered to be on.</p>
+<h1><a class="anchor" id="guarantees_limitations"></a>
+Guarantees and limitations</h1>
+<p>This section describes the conditions under which GLFW can be expected to function, barring bugs in the operating system or drivers. Use of GLFW outside of these limits may work on some platforms, or on some machines, or some of the time, or on some versions of GLFW, but it may break at any time and this will not be considered a bug.</p>
+<h2><a class="anchor" id="lifetime"></a>
+Pointer lifetimes</h2>
+<p>GLFW will never free any pointer you provide to it and you must never free any pointer it provides to you.</p>
+<p>Many GLFW functions return pointers to dynamically allocated structures, strings or arrays, and some callbacks are provided with strings or arrays. These are always managed by GLFW and should never be freed by the application. The lifetime of these pointers is documented for each GLFW function and callback. If you need to keep this data, you must copy it before its lifetime expires.</p>
+<p>Many GLFW functions accept pointers to structures or strings allocated by the application. These are never freed by GLFW and are always the responsibility of the application. If GLFW needs to keep the data in these structures or strings, it is copied before the function returns.</p>
+<p>Pointer lifetimes are guaranteed not to be shortened in future minor or patch releases.</p>
+<h2><a class="anchor" id="reentrancy"></a>
+Reentrancy</h2>
+<p>GLFW event processing and object destruction are not reentrant. This means that the following functions must not be called from any callback function:</p>
+<ul>
+<li><a class="el" href="group__window.html#gacdf43e51376051d2c091662e9fe3d7b2">glfwDestroyWindow</a></li>

+</ul>
+<p>These functions may be made reentrant in future minor or patch releases, but functions not on this list will not be made non-reentrant.</p>
+<h2><a class="anchor" id="thread_safety"></a>
+Thread safety</h2>
+<p>Most GLFW functions must only be called from the main thread (the thread that calls main), but some may be called from any thread once the library has been initialized. Before initialization the whole library is thread-unsafe.</p>
+<p>The reference documentation for every GLFW function states whether it is limited to the main thread.</p>
+<p>Initialization, termination, event processing and the creation and destruction of windows, cursors and OpenGL and OpenGL ES contexts are all restricted to the main thread due to limitations of one or several platforms.</p>
+<p>Because event processing must be performed on the main thread, all callbacks except for the error callback will only be called on that thread. The error callback may be called on any thread, as any GLFW function may generate errors.</p>
+<p>The error code and description may be queried from any thread.</p>

+<p>GLFW uses synchronization objects internally only to manage the per-thread context and error states. Additional synchronization is left to the application.</p>
+<p>Functions that may currently be called from any thread will always remain so, but functions that are currently limited to the main thread may be updated to allow calls from any thread in future releases.</p>
+<h2><a class="anchor" id="compatibility"></a>
+Version compatibility</h2>
+<p>GLFW uses <a href="https://semver.org/">Semantic Versioning</a>. This guarantees source and binary backward compatibility with earlier minor versions of the API. This means that you can drop in a newer version of the library and existing programs will continue to compile and existing binaries will continue to run.</p>
+<p>Once a function or constant has been added, the signature of that function or value of that constant will remain unchanged until the next major version of GLFW. No compatibility of any kind is guaranteed between major versions.</p>
+<p>Undocumented behavior, i.e. behavior that is not described in the documentation, may change at any time until it is documented.</p>
+<p>If the reference documentation and the implementation differ, the reference documentation will almost always take precedence and the implementation will be fixed in the next release. The reference documentation will also take precedence over anything stated in a guide.</p>
+<h2><a class="anchor" id="event_order"></a>
+Event order</h2>
+<p>The order of arrival of related events is not guaranteed to be consistent across platforms. The exception is synthetic key and mouse button release events, which are always delivered after the window defocus event.</p>
+<h1><a class="anchor" id="intro_version"></a>
+Version management</h1>
+<p>GLFW provides mechanisms for identifying what version of GLFW your application was compiled against as well as what version it is currently running against.

+<p>The version string is returned by <a class="el" href="group__init.html#ga23d47dc013fce2bf58036da66079a657">glfwGetVersionString</a>, a function that may be called regardless of whether GLFW is initialized.</p>
+<p><b>Do not use the version string</b> to parse the GLFW library version. The <a class="el" href="group__init.html#ga9f8ffaacf3c269cc48eafbf8b9b71197">glfwGetVersion</a> function already provides the version of the running library binary.</p>
+<p>The format of the string is as follows:</p><ul>
+<li>The version of GLFW</li>
+<li>The name of the window system API</li>
+<li>The name of the context creation API</li>
+<li>Any additional options or APIs</li>
+</ul>
+<p>For example, when compiling GLFW 3.0 with MinGW using the Win32 and WGL back ends, the version string may look something like this:</p>
+<div class="fragment"><div class="line">3.0.0 Win32 WGL MinGW</div>

+<h1><a class="anchor" id="monitor_object"></a>
+Monitor objects</h1>
+<p>A monitor object represents a currently connected monitor and is represented as a pointer to the <a href="https://en.wikipedia.org/wiki/Opaque_data_type">opaque</a> type <a class="el" href="group__monitor.html#ga8d9efd1cde9426692c73fe40437d0ae3">GLFWmonitor</a>. Monitor objects cannot be created or destroyed by the application and retain their addresses until the monitors they represent are disconnected or until the library is <a class="el" href="intro_guide.html#intro_init_terminate">terminated</a>.</p>
+<p>Each monitor has a current video mode, a list of supported video modes, a virtual position, a human-readable name, an estimated physical size and a gamma ramp. One of the monitors is the primary monitor.</p>
+<p>The virtual position of a monitor is in <a class="el" href="intro_guide.html#coordinate_systems">screen coordinates</a> and, together with the current video mode, describes the viewports that the connected monitors provide into the virtual desktop that spans them.</p>
+<p>To see how GLFW views your monitor setup and its available video modes, run the <code>monitors</code> test program.</p>
+<h2><a class="anchor" id="monitor_monitors"></a>
+Retrieving monitors</h2>
+<p>The primary monitor is returned by <a class="el" href="group__monitor.html#ga721867d84c6d18d6790d64d2847ca0b1">glfwGetPrimaryMonitor</a>. It is the user's preferred monitor and is usually the one with global UI elements like task bar or menu bar.</p>

+<h2><a class="anchor" id="monitor_modes"></a>
+Video modes</h2>
+<p>GLFW generally does a good job selecting a suitable video mode when you create a full screen window, change its video mode or make a windowed one full screen, but it is sometimes useful to know exactly which video modes are supported.</p>
+<p>Video modes are represented as <a class="el" href="structGLFWvidmode.html">GLFWvidmode</a> structures. You can get an array of the video modes supported by a monitor with <a class="el" href="group__monitor.html#ga820b0ce9a5237d645ea7cbb4bd383458">glfwGetVideoModes</a>. See the reference documentation for the lifetime of the returned array.</p>

+<h2><a class="anchor" id="monitor_size"></a>
+Physical size</h2>
+<p>The physical size of a monitor in millimetres, or an estimation of it, can be retrieved with <a class="el" href="group__monitor.html#ga7d8bffc6c55539286a6bd20d32a8d7ea">glfwGetMonitorPhysicalSize</a>. This has no relation to its current <em>resolution</em>, i.e. the width and height of its current <a class="el" href="monitor_guide.html#monitor_modes">video mode</a>.</p>
+<div class="fragment"><div class="line"><span class="keywordtype">int</span> width_mm, height_mm;</div>

+</div><!-- fragment --><p>While this can be used to calculate the raw DPI of a monitor, this is often not useful. Instead use the <a class="el" href="monitor_guide.html#monitor_scale">monitor content scale</a> and <a class="el" href="window_guide.html#window_scale">window content scale</a> to scale your content.</p>
+<h2><a class="anchor" id="monitor_scale"></a>
+Content scale</h2>
+<p>The content scale for a monitor can be retrieved with <a class="el" href="group__monitor.html#gad3152e84465fa620b601265ebfcdb21b">glfwGetMonitorContentScale</a>.</p>
+<div class="fragment"><div class="line"><span class="keywordtype">float</span> xscale, yscale;</div>

+</div><!-- fragment --><p>The content scale is the ratio between the current DPI and the platform's default DPI. This is especially important for text and any UI elements. If the pixel dimensions of your UI scaled by this look appropriate on your machine then it should appear at a reasonable size on other machines regardless of their DPI and scaling settings. This relies on the system DPI and scaling settings being somewhat correct.</p>
+<p>The content scale may depend on both the monitor resolution and pixel density and on user settings. It may be very different from the raw DPI calculated from the physical size and current resolution.</p>
+<h2><a class="anchor" id="monitor_pos"></a>
+Virtual position</h2>
+<p>The position of the monitor on the virtual desktop, in <a class="el" href="intro_guide.html#coordinate_systems">screen coordinates</a>, can be retrieved with <a class="el" href="group__monitor.html#ga102f54e7acc9149edbcf0997152df8c9">glfwGetMonitorPos</a>.</p>

+</div><!-- fragment --><h2><a class="anchor" id="monitor_workarea"></a>
+Work area</h2>
+<p>The area of a monitor not occupied by global task bars or menu bars is the work area. This is specified in <a class="el" href="intro_guide.html#coordinate_systems">screen coordinates</a> and can be retrieved with <a class="el" href="group__monitor.html#ga7387a3bdb64bfe8ebf2b9e54f5b6c9d0">glfwGetMonitorWorkarea</a>.</p>

+</div><!-- fragment --><p>Monitor names are not guaranteed to be unique. Two monitors of the same model and make may have the same name. Only the monitor handle is guaranteed to be unique, and only until that monitor is disconnected.</p>
+<h2><a class="anchor" id="monitor_userptr"></a>
+User pointer</h2>

+<h2><a class="anchor" id="moving_threads"></a>
+Removal of threading functions</h2>
+<p>The threading functions have been removed, including the per-thread sleep function. They were fairly primitive, under-used, poorly integrated and took time away from the focus of GLFW (i.e. context, input and window). There are better threading libraries available and native threading support is available in both <a href="https://en.cppreference.com/w/cpp/thread">C++11</a> and <a href="https://en.cppreference.com/w/c/thread">C11</a>, both of which are gaining traction.</p>
+<p>If you wish to use the C++11 or C11 facilities but your compiler doesn't yet support them, see the <a href="https://gitorious.org/tinythread/tinythreadpp">TinyThread++</a> and <a href="https://github.com/tinycthread/tinycthread">TinyCThread</a> projects created by the original author of GLFW. These libraries implement a usable subset of the threading APIs in C++11 and C11, and in fact some GLFW 3 test programs use TinyCThread.</p>
+<p>However, GLFW 3 has better support for <em>use from multiple threads</em> than GLFW 2 had. Contexts can be made current on any thread, although only a single thread at a time, and the documentation explicitly states which functions may be used from any thread and which must only be used from the main thread.</p>

+Removal of image and texture loading</h2>
+<p>The image and texture loading functions have been removed. They only supported the Targa image format, making them mostly useful for beginner level examples. To become of sufficiently high quality to warrant keeping them in GLFW 3, they would need not only to support other formats, but also modern extensions to OpenGL texturing. This would either add a number of external dependencies (libjpeg, libpng, etc.), or force GLFW to ship with inline versions of these libraries.</p>
+<p>As there already are libraries doing this, it is unnecessary both to duplicate the work and to tie the duplicate to GLFW. The resulting library would also be platform-independent, as both OpenGL and stdio are available wherever GLFW is.</p>

GLFW is written in C, not Pascal. Removing this macro means there's one less thing for application programmers to remember, i.e. the requirement to mark all callback functions with <code>GLFWCALL</code>. It also simplifies the creation of DLLs and DLL link libraries, as there's no need to explicitly disable <code>@n</code> entry point suffixes.</p>

+<h2><a class="anchor" id="moving_context"></a>
+Explicit context management</h2>
+<p>Each GLFW 3 window has its own OpenGL context and only you, the application programmer, can know which context should be current on which thread at any given time. Therefore, GLFW 3 leaves that decision to you.</p>
+<p>This means that you need to call <a class="el" href="group__context.html#ga1c04dc242268f827290fe40aa1c91157">glfwMakeContextCurrent</a> after creating a window before you can call any OpenGL functions.</p>
+<h2><a class="anchor" id="moving_hidpi"></a>
+Separation of window and framebuffer sizes</h2>
+<p>Window positions and sizes now use screen coordinates, which may not be the same as pixels on machines with high-DPI monitors. This is important as OpenGL uses pixels, not screen coordinates. For example, the rectangle specified with <code>glViewport</code> needs to use pixels. Therefore, framebuffer size functions have been added. You can retrieve the size of the framebuffer of a window with <a class="el" href="group__window.html#ga0e2637a4161afb283f5300c7f94785c9">glfwGetFramebufferSize</a> function.

+<p>A user attempting to close a window is now just an event like any other. Unlike GLFW 2, windows and contexts created with GLFW 3 will never be destroyed unless you choose them to be. Each window now has a close flag that is set to <code>GLFW_TRUE</code> when the user attempts to close that window. By default, nothing else happens and the window stays visible. It is then up to you to either destroy the window, take some other action or ignore the request.</p>

+<p>The cursor position is now <code>double</code> instead of <code>int</code>, both for the direct functions and for the callback. Some platforms can provide sub-pixel cursor movement and this data is now passed on to the application where available. On platforms where this is not provided, the decimal part is zero.</p>
+<p>GLFW 3 only allows you to position the cursor within a window using <a class="el" href="group__input.html#ga04b03af936d906ca123c8f4ee08b39e7">glfwSetCursorPos</a> (formerly <code>glfwSetMousePos</code>) when that window is active. Unless the window is active, the function fails silently.</p>

+<h2><a class="anchor" id="moving_keys"></a>
+Physical key input</h2>
+<p>GLFW 3 key tokens map to physical keys, unlike in GLFW 2 where they mapped to the values generated by the current keyboard layout. The tokens are named according to the values they would have using the standard US layout, but this is only a convenience, as most programmers are assumed to know that layout. This means that (for example) <code>GLFW_KEY_LEFT_BRACKET</code> is always a single key and is the same key in the same place regardless of what keyboard layouts the users of your program has.</p>
+<p>The key input facility was never meant for text input, although using it that way worked slightly better in GLFW 2. If you were using it to input text, you should be using the character callback instead, on both GLFW 2 and 3. This will give you the characters being input, as opposed to the keys being pressed.</p>
+<p>GLFW 3 has key tokens for all keys on a standard 105 key keyboard, so instead of having to remember whether to check for &lsquo;'a&rsquo;<code>or</code>'A'<code>, you now check for </code>GLFW_KEY_A`.</p>

+Win32 MBCS support</h2>
+<p>The Win32 port of GLFW 3 will not compile in <a href="https://msdn.microsoft.com/en-us/library/5z097dxa.aspx">MBCS mode</a>. However, because the use of the Unicode version of the Win32 API doesn't affect the process as a whole, but only those windows created using it, it's perfectly possible to call MBCS functions from other parts of the same application. Therefore, even if an application using GLFW has MBCS mode code, there's no need for GLFW itself to support it.</p>
+<h2><a class="anchor" id="moving_windows"></a>
+Support for versions of Windows older than XP</h2>
+<p>All explicit support for version of Windows older than XP has been removed. There is no code that actively prevents GLFW 3 from running on these earlier versions, but it uses Win32 functions that those versions lack.</p>
+<p>Windows XP was released in 2001, and by now (January 2015) it has not only replaced almost all earlier versions of Windows, but is itself rapidly being replaced by Windows 7 and 8. The MSDN library doesn't even provide documentation for version older than Windows 2000, making it difficult to maintain compatibility with these versions even if it was deemed worth the effort.</p>
+<p>The Win32 API has also not stood still, and GLFW 3 uses many functions only present on Windows XP or later. Even supporting an OS as new as XP (new from the perspective of GLFW 2, which still supports Windows 95) requires runtime checking for a number of functions that are present only on modern version of Windows.</p>
+<h2><a class="anchor" id="moving_syskeys"></a>

+<p>The ability to disable and capture system-wide hotkeys like Alt+Tab has been removed.

For the matrix helper functions, see math libraries like <a href="https://github.com/g-truc/glm">GLM</a> (for C++), <a href="https://github.com/datenwolf/linmath.h">linmath.h</a> (for C) and others. For the tessellation functions, see for example <a href="https://github.com/memononen/libtess2">libtess2</a>.</p>

+Release notes for version 3.3</h1>
+<p>These are the release notes for version 3.3. For a more detailed view including all fixed bugs see the <a href="https://www.glfw.org/changelog.html">version history</a>.</p>
+<p>Please review the caveats, deprecations and removals if your project was written against an earlier version of GLFW 3.</p>
+<h2><a class="anchor" id="features_33"></a>
+New features in version 3.3</h2>
+<h3><a class="anchor" id="gamepad_33"></a>
+Gamepad input via SDL_GameControllerDB</h3>
+<p>GLFW can now remap game controllers to a standard Xbox-like layout using a built-in copy of SDL_GameControllerDB. Call <a class="el" href="group__input.html#gad0f676860f329d80f7e47e9f06a96f00">glfwJoystickIsGamepad</a> to check if a joystick has a mapping, <a class="el" href="group__input.html#gadccddea8bce6113fa459de379ddaf051">glfwGetGamepadState</a> to retrieve its input state, <a class="el" href="group__input.html#gaed5104612f2fa8e66aa6e846652ad00f">glfwUpdateGamepadMappings</a> to add newer mappings and <a class="el" href="group__input.html#ga5c71e3533b2d384db9317fcd7661b210">glfwGetGamepadName</a> and <a class="el" href="group__input.html#gae168c2c0b8cf2a1cb67c6b3c00bdd543">glfwGetJoystickGUID</a> for mapping related information.</p>
+<p>For more information see <a class="el" href="input_guide.html#gamepad">Gamepad input</a>.</p>
+<h3><a class="anchor" id="moltenvk_33"></a>
+Support for Vulkan on macOS via MoltenVK</h3>
+<p>GLFW now supports <a href="https://moltengl.com/moltenvk/">MoltenVK</a>, a Vulkan implementation on top of the Metal API, and its <code>VK_MVK_macos_surface</code> window surface creation extension. MoltenVK is included in the <a href="https://vulkan.lunarg.com/">macOS Vulkan SDK</a>.</p>
+<p>For more information see <a class="el" href="vulkan_guide.html">Vulkan guide</a>.</p>
+<h3><a class="anchor" id="content_scale_33"></a>
+Content scale queries for DPI-aware rendering</h3>
+<p>GLFW now provides content scales for windows and monitors, i.e. the ratio between their current DPI and the platform's default DPI, with <a class="el" href="group__window.html#gaf5d31de9c19c4f994facea64d2b3106c">glfwGetWindowContentScale</a> and <a class="el" href="group__monitor.html#gad3152e84465fa620b601265ebfcdb21b">glfwGetMonitorContentScale</a>.</p>
+<p>Changes of the content scale of a window can be received with the window content scale callback, set with <a class="el" href="group__window.html#gaf2832ebb5aa6c252a2d261de002c92d6">glfwSetWindowContentScaleCallback</a>.</p>
+<p>The <a class="el" href="window_guide.html#GLFW_SCALE_TO_MONITOR">GLFW_SCALE_TO_MONITOR</a> window hint enables automatic resizing of a window by the content scale of the monitor it is placed, on platforms like Windows where this is necessary. This takes effect both on creation and when the window is moved between monitors. It is related to but different from <a class="el" href="window_guide.html#GLFW_COCOA_RETINA_FRAMEBUFFER_hint">GLFW_COCOA_RETINA_FRAMEBUFFER</a>.</p>
+<p>For more information see <a class="el" href="window_guide.html#window_scale">Window content scale</a>.</p>
+<h3><a class="anchor" id="setwindowattrib_33"></a>
+Support for updating window attributes</h3>
+<p>GLFW now supports changing the <a class="el" href="window_guide.html#GLFW_DECORATED_attrib">GLFW_DECORATED</a>, <a class="el" href="window_guide.html#GLFW_RESIZABLE_attrib">GLFW_RESIZABLE</a>, <a class="el" href="window_guide.html#GLFW_FLOATING_attrib">GLFW_FLOATING</a>, <a class="el" href="window_guide.html#GLFW_AUTO_ICONIFY_attrib">GLFW_AUTO_ICONIFY</a> and <a class="el" href="window_guide.html#GLFW_FOCUS_ON_SHOW_attrib">GLFW_FOCUS_ON_SHOW</a> attributes for existing windows with <a class="el" href="group__window.html#gace2afda29b4116ec012e410a6819033e">glfwSetWindowAttrib</a>.</p>
+<p>For more information see <a class="el" href="window_guide.html#window_attribs">Window attributes</a>.</p>
+<h3><a class="anchor" id="raw_motion_33"></a>
+Support for raw mouse motion</h3>
+<p>GLFW now supports raw (unscaled and unaccelerated) mouse motion in disabled cursor mode with the <a class="el" href="input_guide.html#GLFW_RAW_MOUSE_MOTION">GLFW_RAW_MOUSE_MOTION</a> input mode. Raw mouse motion input is not yet implemented on macOS. Call <a class="el" href="group__input.html#gae4ee0dbd0d256183e1ea4026d897e1c2">glfwRawMouseMotionSupported</a> to check if GLFW can provide raw mouse motion on the current system.</p>
+<p>For more information see <a class="el" href="input_guide.html#raw_mouse_motion">Raw mouse motion</a>.</p>
+<h3><a class="anchor" id="joysticks_33"></a>
+Joystick hats</h3>
+<p>GLFW can now return the state of hats (i.e. POVs or D-pads) of a joystick with <a class="el" href="group__input.html#ga2d8d0634bb81c180899aeb07477a67ea">glfwGetJoystickHats</a>. For compatibility, hats are also exposed as buttons. This can be disabled with the <a class="el" href="intro_guide.html#GLFW_JOYSTICK_HAT_BUTTONS">GLFW_JOYSTICK_HAT_BUTTONS</a> initialization hint.</p>
+<p>For more information see <a class="el" href="input_guide.html#joystick_hat">Joystick hat states</a>.</p>
+<h3><a class="anchor" id="geterror_33"></a>
+Error query</h3>
+<p>GLFW now supports querying the last error code for the calling thread and its human-readable description with <a class="el" href="group__init.html#ga944986b4ec0b928d488141f92982aa18">glfwGetError</a>. This can be used instead of or together with the error callback.</p>
+<p>For more information see <a class="el" href="intro_guide.html#error_handling">Error handling</a>.</p>
+<h3><a class="anchor" id="init_hints_33"></a>
+Support for initialization hints</h3>
+<p>GLFW now supports setting library initialization hints with <a class="el" href="group__init.html#ga110fd1d3f0412822b4f1908c026f724a">glfwInitHint</a>. These must be set before initialization to take effect. Some of these hints are platform specific but are safe to set on any platform.</p>
+<p>For more information see <a class="el" href="intro_guide.html#init_hints">Initialization hints</a>.</p>
+<h3><a class="anchor" id="attention_33"></a>
+User attention request</h3>
+<p>GLFW now supports requesting user attention with <a class="el" href="group__window.html#ga2f8d59323fc4692c1d54ba08c863a703">glfwRequestWindowAttention</a>. Where possible this calls attention to the specified window. On platforms like macOS it calls attention to the whole application.</p>
+<p>For more information see <a class="el" href="window_guide.html#window_attention">Window attention request</a>.</p>
+<h3><a class="anchor" id="maximize_33"></a>
+Window maximization callback</h3>
+<p>GLFW now supports notifying the application that the window has been maximized <a class="el" href="group__window.html#gacbe64c339fbd94885e62145563b6dc93">glfwSetWindowMaximizeCallback</a>. This is called both when the window was maximized by the user and when it was done with <a class="el" href="group__window.html#ga3f541387449d911274324ae7f17ec56b">glfwMaximizeWindow</a>.</p>
+<p>For more information see <a class="el" href="window_guide.html#window_maximize">Window maximization</a>.</p>
+<h3><a class="anchor" id="workarea_33"></a>
+Query for the monitor work area</h3>
+<p>GLFW now supports querying the work area of a monitor, i.e. the area not occupied by task bars or global menu bars, with <a class="el" href="group__monitor.html#ga7387a3bdb64bfe8ebf2b9e54f5b6c9d0">glfwGetMonitorWorkarea</a>. On platforms that lack this concept, the whole area of the monitor is returned.</p>
+<p>For more information see <a class="el" href="monitor_guide.html#monitor_workarea">Work area</a>.</p>
+<h3><a class="anchor" id="transparency_33"></a>
+Transparent windows and framebuffers</h3>
+<p>GLFW now supports the creation of windows with transparent framebuffers on systems with desktop compositing enabled with the <a class="el" href="group__window.html#ga60a0578c3b9449027d683a9c6abb9f14">GLFW_TRANSPARENT_FRAMEBUFFER</a> window hint and attribute. This hint must be set before window creation and leaves any window decorations opaque.</p>
+<p>GLFW now also supports whole window transparency with <a class="el" href="group__window.html#gad09f0bd7a6307c4533b7061828480a84">glfwGetWindowOpacity</a> and <a class="el" href="group__window.html#gac31caeb3d1088831b13d2c8a156802e9">glfwSetWindowOpacity</a>. This value controls the opacity of the whole window including decorations and unlike framebuffer transparency can be changed at any time after window creation.</p>
+<p>For more information see <a class="el" href="window_guide.html#window_transparency">Window transparency</a>.</p>
+<h3><a class="anchor" id="key_scancode_33"></a>
+Query for the scancode of a key</h3>
+<p>GLFW now supports querying the platform dependent scancode of any physical key with <a class="el" href="group__input.html#ga67ddd1b7dcbbaff03e4a76c0ea67103a">glfwGetKeyScancode</a>.</p>
+<p>For more information see <a class="el" href="input_guide.html#input_key">Key input</a>.</p>
+<h3><a class="anchor" id="center_cursor_33"></a>
+Cursor centering window hint</h3>
+<p>GLFW now supports controlling whether the cursor is centered over newly created full screen windows with the <a class="el" href="window_guide.html#GLFW_CENTER_CURSOR_hint">GLFW_CENTER_CURSOR</a> window hint. It is enabled by default.</p>
+<h3><a class="anchor" id="cursor_hover_33"></a>
+Mouse cursor hover window attribute</h3>
+<p>GLFW now supports polling whether the cursor is hovering over the window content area with the <a class="el" href="window_guide.html#GLFW_HOVERED_attrib">GLFW_HOVERED</a> window attribute. This attribute corresponds to the <a class="el" href="input_guide.html#cursor_enter">cursor enter/leave</a> event.</p>
+<h3><a class="anchor" id="focusonshow_33"></a>
+Window hint and attribute for input focus on show</h3>
+<p>GLFW now has the <a class="el" href="window_guide.html#GLFW_DECORATED_hint">GLFW_FOCUS_ON_SHOW</a> window hint and attribute for controlling whether a window gets input focus when shown. It is enabled by default. It applies both when creating an visible window with <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> and when showing it with <a class="el" href="group__window.html#ga61be47917b72536a148300f46494fc66">glfwShowWindow</a>.</p>
+<p>This is a workaround for GLFW 3.0 lacking <a class="el" href="group__window.html#ga873780357abd3f3a081d71a40aae45a1">glfwFocusWindow</a> and will be corrected in the next major version.</p>
+<p>For more information see <a class="el" href="window_guide.html#window_hide">Window visibility</a>.</p>
+<h3><a class="anchor" id="device_userptr_33"></a>
+Monitor and joystick user pointers</h3>
+<p>GLFW now supports setting and querying user pointers for connected monitors and joysticks with <a class="el" href="group__monitor.html#ga702750e24313a686d3637297b6e85fda">glfwSetMonitorUserPointer</a>, <a class="el" href="group__monitor.html#gac2d4209016b049222877f620010ed0d8">glfwGetMonitorUserPointer</a>, <a class="el" href="group__input.html#ga6b2f72d64d636b48a727b437cbb7489e">glfwSetJoystickUserPointer</a> and <a class="el" href="group__input.html#ga06290acb7ed23895bf26b8e981827ebd">glfwGetJoystickUserPointer</a>.</p>
+<p>For more information see <a class="el" href="monitor_guide.html#monitor_userptr">User pointer</a> and <a class="el" href="input_guide.html#joystick_userptr">Joystick user pointer</a>.</p>
+<h3><a class="anchor" id="macos_nib_33"></a>
+macOS menu bar from nib file</h3>
+<p>GLFW will now load a <code>MainMenu.nib</code> file if found in the <code>Contents/Resources</code> directory of the application bundle, as a way to replace the GLFW menu bar without recompiling GLFW. This behavior can be disabled with the <a class="el" href="intro_guide.html#GLFW_COCOA_MENUBAR_hint">GLFW_COCOA_MENUBAR</a> initialization hint.</p>
+<h3><a class="anchor" id="glext_33"></a>
+Support for more context creation extensions</h3>
+<p>The context hint <a class="el" href="window_guide.html#GLFW_SRGB_CAPABLE">GLFW_SRGB_CAPABLE</a> now supports OpenGL ES via <code>WGL_EXT_colorspace</code>, the context hint <a class="el" href="group__window.html#ga5a52fdfd46d8249c211f923675728082">GLFW_CONTEXT_NO_ERROR</a> now supports <code>WGL_ARB_create_context_no_error</code> and <code>GLX_ARB_create_context_no_error</code>, the context hint <a class="el" href="group__window.html#ga72b648a8378fe3310c7c7bbecc0f7be6">GLFW_CONTEXT_RELEASE_BEHAVIOR</a> now supports <code>EGL_KHR_context_flush_control</code> and <a class="el" href="group__context.html#ga35f1837e6f666781842483937612f163">glfwGetProcAddress</a> now supports <code>EGL_KHR_get_all_proc_addresses</code>.</p>
+<h3><a class="anchor" id="osmesa_33"></a>
+OSMesa off-screen context creation support</h3>
+<p>GLFW now supports creating off-screen OpenGL contexts using <a href="https://www.mesa3d.org/osmesa.html">OSMesa</a> by setting <a class="el" href="window_guide.html#GLFW_CONTEXT_CREATION_API_hint">GLFW_CONTEXT_CREATION_API</a> to <code>GLFW_OSMESA_CONTEXT_API</code>. Native access function have been added to retrieve the OSMesa color and depth buffers.</p>
+<p>There is also a new null backend that uses OSMesa as its native context creation API, intended for automated testing. This backend does not provide input.</p>
+<h2><a class="anchor" id="caveats_33"></a>
+Caveats for version 3.3</h2>
+<h3><a class="anchor" id="joystick_layout_33"></a>
+Layout of joysticks have changed</h3>
+<p>The way joystick elements are arranged have changed to match SDL2 in order to support SDL_GameControllerDB mappings. The layout of joysticks may change again if required for compatibility with SDL2. If you need a known and stable layout for game controllers, see if you can switch to <a class="el" href="input_guide.html#gamepad">Gamepad input</a>.</p>
+<p>Existing code that depends on a specific joystick layout will likely have to be updated.</p>
+<h3><a class="anchor" id="wait_events_33"></a>
+No window required to wait for events</h3>
+<p>The <a class="el" href="group__window.html#ga554e37d781f0a997656c26b2c56c835e">glfwWaitEvents</a> and <a class="el" href="group__window.html#ga605a178db92f1a7f1a925563ef3ea2cf">glfwWaitEventsTimeout</a> functions no longer need a window to be created to wait for events. Before version 3.3 these functions would return immediately if there were no user-created windows. On platforms where only windows can receive events, an internal helper window is used.</p>
+<p>Existing code that depends on the earlier behavior will likely have to be updated.</p>
+<h3><a class="anchor" id="gamma_ramp_size_33"></a>
+Gamma ramp size of 256 may be rejected</h3>
+<p>The documentation for versions before 3.3 stated that a gamma ramp size of 256 would always be accepted. This was never the case on X11 and could lead to artifacts on macOS. The <a class="el" href="group__monitor.html#ga6ac582625c990220785ddd34efa3169a">glfwSetGamma</a> function has been updated to always generate a ramp of the correct size.</p>
+<p>Existing code that hardcodes a size of 256 should be updated to use the size of the current ramp of a monitor when setting a new ramp for that monitor.</p>
+<h3><a class="anchor" id="xinput_deadzone_33"></a>
+Windows XInput deadzone removed</h3>
+<p>GLFW no longer applies any deadzone to the input state received from the XInput API. This was never done for any other platform joystick API so this change makes the behavior more consistent but you will need to apply your own deadzone if desired.</p>
+<h3><a class="anchor" id="x11_clipboard_33"></a>
+X11 clipboard transfer limits</h3>
+<p>GLFW now supports reading clipboard text via the <code>INCR</code> method, which removes the limit on how much text can be read with <a class="el" href="group__input.html#ga5aba1d704d9ab539282b1fbe9f18bb94">glfwGetClipboardString</a>. However, writing via this method is not yet supported, so you may not be able to write a very large string with <a class="el" href="group__input.html#gaba1f022c5eb07dfac421df34cdcd31dd">glfwSetClipboardString</a> even if you read it from the clipboard earlier.</p>
+<p>The exact size limit for writing to the clipboard is negotiated with each receiving application but is at least several tens of kilobytes. Note that only the read limit has changed. Any string that could be written before still can be.</p>
+<h3><a class="anchor" id="x11_linking_33"></a>
+X11 extension libraries are loaded dynamically</h3>
+<p>GLFW now loads all X11 extension libraries at initialization. The only X11 library you need to link against is <code>libX11</code>. The header files for the extension libraries are still required for compilation.</p>
+<p>Existing projects and makefiles that link GLFW directly against the extension libraries should still build correctly but will add these libraries as load-time dependencies.</p>
+<h3><a class="anchor" id="cmake_version_33"></a>
+CMake 3.0 or later is required</h3>
+<p>The minimum CMake version has been raised from 2.8.12 to 3.0. This is only a requirement of the GLFW CMake files. The GLFW source files do not depend on CMake.</p>
+<h2><a class="anchor" id="deprecations_33"></a>
+Deprecations in version 3.3</h2>
+<h3><a class="anchor" id="charmods_callback_33"></a>
+Character with modifiers callback</h3>
+<p>The character with modifiers callback set with <a class="el" href="group__input.html#ga0b7f4ad13c2b17435ff13b6dcfb4e43c">glfwSetCharModsCallback</a> has been deprecated and should if possible not be used.</p>
+<p>Existing code should still work but further bug fixes will likely not be made. The callback will be removed in the next major version.</p>
+<h3><a class="anchor" id="clipboard_window_33"></a>
+Window parameter to clipboard functions</h3>
+<p>The window parameter of the clipboard functions <a class="el" href="group__input.html#ga5aba1d704d9ab539282b1fbe9f18bb94">glfwGetClipboardString</a> and <a class="el" href="group__input.html#gaba1f022c5eb07dfac421df34cdcd31dd">glfwSetClipboardString</a> has been deprecated and is no longer used on any platform. On platforms where the clipboard must be owned by a specific window, an internal helper window is used.</p>
+<p>Existing code should still work unless it depends on a specific window owning the clipboard. New code may pass <code>NULL</code> as the window argument. The parameter will be removed in a future release.</p>
+<h2><a class="anchor" id="removals_33"></a>
+Removals in 3.3</h2>
+<h3><a class="anchor" id="macos_options_33"></a>
+macOS specific CMake options and macros</h3>
+<p>The <code>GLFW_USE_RETINA</code>, <code>GLFW_USE_CHDIR</code> and <code>GLFW_USE_MENUBAR</code> CMake options and the <code>_GLFW_USE_RETINA</code>, <code>_GLFW_USE_CHDIR</code> and <code>_GLFW_USE_MENUBAR</code> compile-time macros have been removed.</p>
+<p>These options and macros are replaced by the window hint <a class="el" href="window_guide.html#GLFW_COCOA_RETINA_FRAMEBUFFER_hint">GLFW_COCOA_RETINA_FRAMEBUFFER</a> and the init hints <a class="el" href="intro_guide.html#GLFW_COCOA_CHDIR_RESOURCES_hint">GLFW_COCOA_CHDIR_RESOURCES</a> and <a class="el" href="intro_guide.html#GLFW_COCOA_MENUBAR_hint">GLFW_COCOA_MENUBAR</a>.</p>
+<p>Existing projects and makefiles that set these options or define these macros during compilation of GLFW will still build but it will have no effect and the default behaviors will be used.</p>
+<h3><a class="anchor" id="vulkan_sdk_33"></a>
+LunarG Vulkan SDK dependency</h3>
+<p>The GLFW test programs that previously depended on the LunarG Vulkan SDK now instead uses a Vulkan loader generated by <a href="https://github.com/Dav1dde/glad">glad2</a>. This means the GLFW CMake files no longer look for the Vulkan SDK.</p>
+<p>Existing CMake projects that depended on the Vulkan SDK cache variables from GLFW will need to call <code>find_package(Vulkan)</code> themselves. CMake 3.7 and later already comes with a <a href="https://cmake.org/cmake/help/latest/module/FindVulkan.html">Vulkan find module</a> similar to the one GLFW previously included.</p>
+<h3><a class="anchor" id="lib_suffix_33"></a>
+CMake option LIB_SUFFIX</h3>
+<p>The <code>LIB_SUFFIX</code> CMake option has been removed. GLFW now uses the GNUInstallDirs CMake package to handle platform specific details like the library directory suffix and the <code>LIB_SUFFIX</code> CMake option has been removed.</p>
+<p>Existing projects and makefiles that set the <code>LIB_SUFFIX</code> option will use the suffix chosen by the GNUInstallDirs package and the option will be ignored.</p>
+<h3><a class="anchor" id="mir_removed_33"></a>
+Mir support</h3>
+<p>The experimental Mir support has been completely removed as the Mir project has implemented support for the Wayland protocol and is recommending that applications use that instead.</p>
+<p>Existing projects and makefiles that select Mir when compiling GLFW will fail. Use Wayland or X11 instead.</p>

+<dl class="section see"><dt>See also</dt><dd><a class="el" href="window_guide.html#window_size">Window size</a></dd></dl>
+<h3><a class="anchor" id="news_31_autoiconify"></a>
+Simultaneous multi-monitor rendering</h3>
+<p>GLFW now supports disabling auto-iconification of full screen windows with the <a class="el" href="window_guide.html#GLFW_AUTO_ICONIFY_hint">GLFW_AUTO_ICONIFY</a> window hint. This is intended for people building multi-monitor installations, where you need windows to stay in full screen despite losing input focus.</p>
+<h3><a class="anchor" id="news_31_floating"></a>
+Floating windows</h3>
+<p>GLFW now supports floating windows, also called topmost or always on top, for easier debugging with the <a class="el" href="group__window.html#ga7fb0be51407783b41adbf5bec0b09d80">GLFW_FLOATING</a> window hint and attribute.</p>
+<h3><a class="anchor" id="news_31_focused"></a>
+Initially unfocused windows</h3>
+<p>GLFW now supports preventing a windowed mode window from gaining input focus on creation, with the <a class="el" href="window_guide.html#GLFW_FOCUSED_hint">GLFW_FOCUSED</a> window hint.</p>
+<h3><a class="anchor" id="news_31_direct"></a>
+Direct access for window attributes and cursor position</h3>
+<p>GLFW now queries the window input focus, visibility and iconification attributes and the cursor position directly instead of returning cached data.</p>
+<h3><a class="anchor" id="news_31_charmods"></a>
+Character with modifiers callback</h3>
+<p>GLFW now provides a callback for character events with modifier key bits. The callback is set with <a class="el" href="group__input.html#ga0b7f4ad13c2b17435ff13b6dcfb4e43c">glfwSetCharModsCallback</a>. Unlike the regular character callback, this will report character events that will not result in a character being input, for example if the Control key is held down.</p>
+<dl class="section see"><dt>See also</dt><dd><a class="el" href="input_guide.html#input_char">Text input</a></dd></dl>
+<h3><a class="anchor" id="news_31_single"></a>
+Single buffered framebuffers</h3>
+<p>GLFW now supports the creation of single buffered windows, with the <a class="el" href="window_guide.html#GLFW_DOUBLEBUFFER">GLFW_DOUBLEBUFFER</a> hint.</p>
+<h3><a class="anchor" id="news_31_glext"></a>
+Macro for including extension header</h3>
+<p>GLFW now includes the extension header appropriate for the chosen OpenGL or OpenGL ES header when <a class="el" href="build_guide.html#GLFW_INCLUDE_GLEXT">GLFW_INCLUDE_GLEXT</a> is defined. GLFW does not provide these headers. They must be provided by your development environment or your OpenGL or OpenGL ES SDK.</p>
+<h3><a class="anchor" id="news_31_release"></a>
+Context release behaviors</h3>
+<p>GLFW now supports controlling and querying whether the pipeline is flushed when a context is made non-current, with the <a class="el" href="group__window.html#ga72b648a8378fe3310c7c7bbecc0f7be6">GLFW_CONTEXT_RELEASE_BEHAVIOR</a> hint and attribute, provided the machine supports the <code>GL_KHR_context_flush_control</code> extension.</p>
+<h3><a class="anchor" id="news_31_wayland"></a>
+(Experimental) Wayland support</h3>
+<p>GLFW now has an <em>experimental</em> Wayland display protocol backend that can be selected on Linux with a CMake option.</p>
+<h3><a class="anchor" id="news_31_mir"></a>
+(Experimental) Mir support</h3>
+<p>GLFW now has an <em>experimental</em> Mir display server backend that can be selected on Linux with a CMake option.</p>
+<h1><a class="anchor" id="news_30"></a>
+Release notes for 3.0</h1>
+<p>These are the release notes for version 3.0. For a more detailed view including all fixed bugs see the <a href="https://www.glfw.org/changelog.html">version history</a>.</p>
+<h2><a class="anchor" id="features_30"></a>
+New features in version 3.0</h2>
+<h3><a class="anchor" id="news_30_cmake"></a>
+CMake build system</h3>
+<p>GLFW now uses the CMake build system instead of the various makefiles and project files used by earlier versions. CMake is available for all platforms supported by GLFW, is present in most package systems and can generate makefiles and/or project files for most popular development environments.</p>
+<p>For more information on how to use CMake, see the <a href="https://cmake.org/cmake/help/documentation.html">CMake manual</a>.</p>
+<h3><a class="anchor" id="news_30_multiwnd"></a>
+Multi-window support</h3>
+<p>GLFW now supports the creation of multiple windows, each with their own OpenGL or OpenGL ES context, and all window functions now take a window handle. Event callbacks are now per-window and are provided with the handle of the window that received the event. The <a class="el" href="group__context.html#ga1c04dc242268f827290fe40aa1c91157">glfwMakeContextCurrent</a> function has been added to select which context is current on a given thread.</p>
+<h3><a class="anchor" id="news_30_multimon"></a>
+Multi-monitor support</h3>
+<p>GLFW now explicitly supports multiple monitors. They can be enumerated with <a class="el" href="group__monitor.html#ga3fba51c8bd36491d4712aa5bd074a537">glfwGetMonitors</a>, queried with <a class="el" href="group__monitor.html#ga820b0ce9a5237d645ea7cbb4bd383458">glfwGetVideoModes</a>, <a class="el" href="group__monitor.html#ga102f54e7acc9149edbcf0997152df8c9">glfwGetMonitorPos</a>, <a class="el" href="group__monitor.html#ga79a34ee22ff080ca954a9663e4679daf">glfwGetMonitorName</a> and <a class="el" href="group__monitor.html#ga7d8bffc6c55539286a6bd20d32a8d7ea">glfwGetMonitorPhysicalSize</a>, and specified at window creation to make the newly created window full screen on that specific monitor.</p>
+<h3><a class="anchor" id="news_30_unicode"></a>
+Unicode support</h3>
+<p>All string arguments to GLFW functions and all strings returned by GLFW now use the UTF-8 encoding. This includes the window title, error string, clipboard text, monitor and joystick names as well as the extension function arguments (as ASCII is a subset of UTF-8).</p>
+<h3><a class="anchor" id="news_30_clipboard"></a>
+Clipboard text I/O</h3>
+<p>GLFW now supports reading and writing plain text to and from the system clipboard, with the <a class="el" href="group__input.html#ga5aba1d704d9ab539282b1fbe9f18bb94">glfwGetClipboardString</a> and <a class="el" href="group__input.html#gaba1f022c5eb07dfac421df34cdcd31dd">glfwSetClipboardString</a> functions.</p>
+<h3><a class="anchor" id="news_30_gamma"></a>
+Gamma ramp support</h3>
+<p>GLFW now supports setting and reading back the gamma ramp of monitors, with the <a class="el" href="group__monitor.html#gab7c41deb2219bde3e1eb756ddaa9ec80">glfwGetGammaRamp</a> and <a class="el" href="group__monitor.html#ga583f0ffd0d29613d8cd172b996bbf0dd">glfwSetGammaRamp</a> functions. There is also <a class="el" href="group__monitor.html#ga6ac582625c990220785ddd34efa3169a">glfwSetGamma</a>, which generates a ramp from a gamma value and then sets it.</p>
+<h3><a class="anchor" id="news_30_gles"></a>
+OpenGL ES support</h3>
+<p>GLFW now supports the creation of OpenGL ES contexts, by setting the <a class="el" href="window_guide.html#GLFW_CLIENT_API_hint">GLFW_CLIENT_API</a> hint to <code>GLFW_OPENGL_ES_API</code>, where creation of such contexts are supported. Note that GLFW <em>does not implement</em> OpenGL ES, so your driver must provide support in a way usable by GLFW. Modern Nvidia and Intel drivers support creation of OpenGL ES context using the GLX and WGL APIs, while AMD provides an EGL implementation instead.</p>
+<h3><a class="anchor" id="news_30_egl"></a>
+(Experimental) EGL support</h3>
+<p>GLFW now has an experimental EGL context creation back end that can be selected through CMake options.</p>
+<h3><a class="anchor" id="news_30_hidpi"></a>
+High-DPI support</h3>
+<p>GLFW now supports high-DPI monitors on both Windows and macOS, giving windows full resolution framebuffers where other UI elements are scaled up. To achieve this, <a class="el" href="group__window.html#ga0e2637a4161afb283f5300c7f94785c9">glfwGetFramebufferSize</a> and <a class="el" href="group__window.html#gab3fb7c3366577daef18c0023e2a8591f">glfwSetFramebufferSizeCallback</a> have been added. These work with pixels, while the rest of the GLFW API works with screen coordinates. This is important as OpenGL uses pixels, not screen coordinates.</p>
+<h3><a class="anchor" id="news_30_error"></a>
+Error callback</h3>
+<p>GLFW now has an error callback, which can provide your application with much more detailed diagnostics than was previously possible. The callback is passed an error code and a description string.</p>
+<h3><a class="anchor" id="news_30_wndptr"></a>
+Per-window user pointer</h3>
+<p>Each window now has a user-defined pointer, retrieved with <a class="el" href="group__window.html#ga17807ce0f45ac3f8bb50d6dcc59a4e06">glfwGetWindowUserPointer</a> and set with <a class="el" href="group__window.html#ga3d2fc6026e690ab31a13f78bc9fd3651">glfwSetWindowUserPointer</a>, to make it easier to integrate GLFW into C++ code.</p>
+<h3><a class="anchor" id="news_30_iconifyfun"></a>
+Window iconification callback</h3>
+<p>Each window now has a callback for iconification and restoration events, which is set with <a class="el" href="group__window.html#gac793e9efd255567b5fb8b445052cfd3e">glfwSetWindowIconifyCallback</a>.</p>
+<h3><a class="anchor" id="news_30_wndposfun"></a>
+Window position callback</h3>
+<p>Each window now has a callback for position events, which is set with <a class="el" href="group__window.html#ga08bdfbba88934f9c4f92fd757979ac74">glfwSetWindowPosCallback</a>.</p>
+<h3><a class="anchor" id="news_30_wndpos"></a>
+Window position query</h3>
+<p>The position of a window can now be retrieved using <a class="el" href="group__window.html#ga73cb526c000876fd8ddf571570fdb634">glfwGetWindowPos</a>.</p>
+<h3><a class="anchor" id="news_30_focusfun"></a>
+Window focus callback</h3>
+<p>Each windows now has a callback for focus events, which is set with <a class="el" href="group__window.html#gac2d83c4a10f071baf841f6730528e66c">glfwSetWindowFocusCallback</a>.</p>
+<h3><a class="anchor" id="news_30_enterleave"></a>
+Cursor enter/leave callback</h3>
+<p>Each window now has a callback for when the mouse cursor enters or leaves its content area, which is set with <a class="el" href="group__input.html#gad27f8ad0142c038a281466c0966817d8">glfwSetCursorEnterCallback</a>.</p>
+<h3><a class="anchor" id="news_30_wndtitle"></a>
+Initial window title</h3>
+<p>The title of a window is now specified at creation time, as one of the arguments to <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>.</p>
+<h3><a class="anchor" id="news_30_hidden"></a>
+Hidden windows</h3>
+<p>Windows can now be hidden with <a class="el" href="group__window.html#ga49401f82a1ba5f15db5590728314d47c">glfwHideWindow</a>, shown using <a class="el" href="group__window.html#ga61be47917b72536a148300f46494fc66">glfwShowWindow</a> and created initially hidden with the <a class="el" href="group__window.html#gafb3cdc45297e06d8f1eb13adc69ca6c4">GLFW_VISIBLE</a> window hint and attribute. This allows for off-screen rendering in a way compatible with most drivers, as well as moving a window to a specific position before showing it.</p>
+<h3><a class="anchor" id="news_30_undecorated"></a>
+Undecorated windows</h3>
+<p>Windowed mode windows can now be created without decorations, e.g. things like a frame, a title bar, with the <a class="el" href="group__window.html#ga21b854d36314c94d65aed84405b2f25e">GLFW_DECORATED</a> window hint and attribute. This allows for the creation of things like splash screens.</p>
+<h3><a class="anchor" id="news_30_keymods"></a>
+Modifier key bit masks</h3>
+<p><a class="el" href="group__mods.html">Modifier key bit mask</a> parameters have been added to the <a class="el" href="group__input.html#ga39893a4a7e7c3239c98d29c9e084350c">mouse button</a> and <a class="el" href="group__input.html#ga0192a232a41e4e82948217c8ba94fdfd">key</a> callbacks.</p>
+<h3><a class="anchor" id="news_30_scancode"></a>
+Platform-specific scancodes</h3>
+<p>A scancode parameter has been added to the <a class="el" href="group__input.html#ga0192a232a41e4e82948217c8ba94fdfd">key callback</a>. Keys that don't have a <a class="el" href="group__keys.html">key token</a> still get passed on with the key parameter set to <code>GLFW_KEY_UNKNOWN</code>. These scancodes will vary between machines and are intended to be used for key bindings.</p>
+<h3><a class="anchor" id="news_30_jsname"></a>
+Joystick names</h3>
+<p>The name of a joystick can now be retrieved using <a class="el" href="group__input.html#gafbe3e51f670320908cfe4e20d3e5559e">glfwGetJoystickName</a>.</p>

+<div class="textblock"><p>This guide takes you through writing a simple application using GLFW 3. The application will create a window and OpenGL context, render a rotating triangle and exit when the user closes the window or presses <em>Escape</em>. This guide will introduce a few of the most commonly used functions, but there are many more.</p>
+<p>This guide assumes no experience with earlier versions of GLFW. If you have used GLFW 2 in the past, read <a class="el" href="moving_guide.html">Moving from GLFW 2 to 3</a>, as some functions behave differently in GLFW 3.</p>
+<h1><a class="anchor" id="quick_steps"></a>
+Step by step</h1>
+<h2><a class="anchor" id="quick_include"></a>
+Including the GLFW header</h2>
+<p>In the source files of your application where you use OpenGL or GLFW, you need to include the GLFW 3 header file.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#include &lt;<a class="code" href="glfw3_8h.html">GLFW/glfw3.h</a>&gt;</span></div>
+</div><!-- fragment --><p>This defines all the constants, types and function prototypes of the GLFW API. It also includes the OpenGL header from your development environment and defines all the constants and types necessary for it to work on your platform without including any platform-specific headers.</p>
+<p>In other words:</p>
+<ul>
+<li>Do <em>not</em> include the OpenGL header yourself, as GLFW does this for you in a platform-independent way</li>
+<li>Do <em>not</em> include <code>windows.h</code> or other platform-specific headers unless you plan on using those APIs yourself</li>
+<li>If you <em>do</em> need to include such headers, include them <em>before</em> the GLFW header and it will detect this</li>
+</ul>
+<p>On some platforms supported by GLFW the OpenGL header and link library only expose older versions of OpenGL. The most extreme case is Windows, which only exposes OpenGL 1.2. The easiest way to work around this is to use an <a class="el" href="context_guide.html#context_glext_auto">extension loader library</a>.</p>
+<p>If you are using such a library then you should include its header <em>before</em> the GLFW header. This lets it replace the OpenGL header included by GLFW without conflicts. This example uses <a href="https://github.com/Dav1dde/glad">glad2</a>, but the same rule applies to all such libraries.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#include &lt;glad/gl.h&gt;</span></div>
+<div class="line"><span class="preprocessor">#include &lt;<a class="code" href="glfw3_8h.html">GLFW/glfw3.h</a>&gt;</span></div>
+</div><!-- fragment --><h2><a class="anchor" id="quick_init_term"></a>
+Initializing and terminating GLFW</h2>
+<p>Before you can use most GLFW functions, the library must be initialized. On successful initialization, <code>GLFW_TRUE</code> is returned. If an error occurred, <code>GLFW_FALSE</code> is returned.</p>
+<div class="fragment"><div class="line"><span class="keywordflow">if</span> (!<a class="code" href="group__init.html#ga317aac130a235ab08c6db0834907d85e">glfwInit</a>())</div>
+<div class="line">{</div>
+<div class="line">    <span class="comment">// Initialization failed</span></div>
+<div class="line">}</div>
+</div><!-- fragment --><p>Note that <code>GLFW_TRUE</code> and <code>GLFW_FALSE</code> are and will always be one and zero.</p>
+<p>When you are done using GLFW, typically just before the application exits, you need to terminate GLFW.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__init.html#gaaae48c0a18607ea4a4ba951d939f0901">glfwTerminate</a>();</div>
+</div><!-- fragment --><p>This destroys any remaining windows and releases any other resources allocated by GLFW. After this call, you must initialize GLFW again before using any GLFW functions that require it.</p>
+<h2><a class="anchor" id="quick_capture_error"></a>
+Setting an error callback</h2>
+<p>Most events are reported through callbacks, whether it's a key being pressed, a GLFW window being moved, or an error occurring. Callbacks are C functions (or C++ static methods) that are called by GLFW with arguments describing the event.</p>
+<p>In case a GLFW function fails, an error is reported to the GLFW error callback. You can receive these reports with an error callback. This function must have the signature below but may do anything permitted in other callbacks.</p>
+<div class="fragment"><div class="line"><span class="keywordtype">void</span> error_callback(<span class="keywordtype">int</span> error, <span class="keyword">const</span> <span class="keywordtype">char</span>* description)</div>
+<div class="line">{</div>
+<div class="line">    fprintf(stderr, <span class="stringliteral">&quot;Error: %s\n&quot;</span>, description);</div>
+<div class="line">}</div>
+</div><!-- fragment --><p>Callback functions must be set, so GLFW knows to call them. The function to set the error callback is one of the few GLFW functions that may be called before initialization, which lets you be notified of errors both during and after initialization.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__init.html#gaff45816610d53f0b83656092a4034f40">glfwSetErrorCallback</a>(error_callback);</div>
+</div><!-- fragment --><h2><a class="anchor" id="quick_create_window"></a>
+Creating a window and context</h2>
+<p>The window and its OpenGL context are created with a single call to <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>, which returns a handle to the created combined window and context object</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga3c96d80d363e67d13a41b5d1821f3242">GLFWwindow</a>* window = <a class="code" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>(640, 480, <span class="stringliteral">&quot;My Title&quot;</span>, NULL, NULL);</div>
+<div class="line"><span class="keywordflow">if</span> (!window)</div>
+<div class="line">{</div>
+<div class="line">    <span class="comment">// Window or OpenGL context creation failed</span></div>
+<div class="line">}</div>
+</div><!-- fragment --><p>This creates a 640 by 480 windowed mode window with an OpenGL context. If window or OpenGL context creation fails, <code>NULL</code> will be returned. You should always check the return value. While window creation rarely fails, context creation depends on properly installed drivers and may fail even on machines with the necessary hardware.</p>
+<p>By default, the OpenGL context GLFW creates may have any version. You can require a minimum OpenGL version by setting the <code>GLFW_CONTEXT_VERSION_MAJOR</code> and <code>GLFW_CONTEXT_VERSION_MINOR</code> hints <em>before</em> creation. If the required minimum version is not supported on the machine, context (and window) creation fails.</p>

+Making the OpenGL context current</h2>
+<p>Before you can use the OpenGL API, you must have a current OpenGL context.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__context.html#ga1c04dc242268f827290fe40aa1c91157">glfwMakeContextCurrent</a>(window);</div>
+</div><!-- fragment --><p>The context will remain current until you make another context current or until the window owning the current context is destroyed.</p>
+<p>If you are using an <a class="el" href="context_guide.html#context_glext_auto">extension loader library</a> to access modern OpenGL then this is when to initialize it, as the loader needs a current context to load from. This example uses <a href="https://github.com/Dav1dde/glad">glad</a>, but the same rule applies to all such libraries.</p>
+<div class="fragment"><div class="line">gladLoadGL(<a class="code" href="group__context.html#ga35f1837e6f666781842483937612f163">glfwGetProcAddress</a>);</div>
+</div><!-- fragment --><h2><a class="anchor" id="quick_window_close"></a>
+Checking the window close flag</h2>
+<p>Each window has a flag indicating whether the window should be closed.</p>
+<p>When the user attempts to close the window, either by pressing the close widget in the title bar or using a key combination like Alt+F4, this flag is set to 1. Note that <b>the window isn't actually closed</b>, so you are expected to monitor this flag and either destroy the window or give some kind of feedback to the user.</p>
+<div class="fragment"><div class="line"><span class="keywordflow">while</span> (!<a class="code" href="group__window.html#ga24e02fbfefbb81fc45320989f8140ab5">glfwWindowShouldClose</a>(window))</div>
+<div class="line">{</div>
+<div class="line">    <span class="comment">// Keep running</span></div>
+<div class="line">}</div>
+</div><!-- fragment --><p>You can be notified when the user is attempting to close the window by setting a close callback with <a class="el" href="group__window.html#gada646d775a7776a95ac000cfc1885331">glfwSetWindowCloseCallback</a>. The callback will be called immediately after the close flag has been set.</p>
+<p>You can also set it yourself with <a class="el" href="group__window.html#ga49c449dde2a6f87d996f4daaa09d6708">glfwSetWindowShouldClose</a>. This can be useful if you want to interpret other kinds of input as closing the window, like for example pressing the <em>Escape</em> key.</p>
+<h2><a class="anchor" id="quick_key_input"></a>
+Receiving input events</h2>
+<p>Each window has a large number of callbacks that can be set to receive all the various kinds of events. To receive key press and release events, create a key callback function.</p>

+<h2><a class="anchor" id="quick_render"></a>
+Rendering with OpenGL</h2>
+<p>Once you have a current OpenGL context, you can use OpenGL normally. In this tutorial, a multi-colored rotating triangle will be rendered. The framebuffer size needs to be retrieved for <code>glViewport</code>.</p>
+<div class="fragment"><div class="line"><span class="keywordtype">int</span> width, height;</div>
+<div class="line"><a class="code" href="group__window.html#ga0e2637a4161afb283f5300c7f94785c9">glfwGetFramebufferSize</a>(window, &amp;width, &amp;height);</div>
+<div class="line">glViewport(0, 0, width, height);</div>
+</div><!-- fragment --><p>You can also set a framebuffer size callback using <a class="el" href="group__window.html#gab3fb7c3366577daef18c0023e2a8591f">glfwSetFramebufferSizeCallback</a> and be notified when the size changes.</p>
+<p>Actual rendering with OpenGL is outside the scope of this tutorial, but there are <a href="https://open.gl/">many</a> <a href="https://learnopengl.com/">excellent</a> <a href="http://openglbook.com/">tutorial</a> <a href="http://ogldev.atspace.co.uk/">sites</a> that teach modern OpenGL. Some of them use GLFW to create the context and window while others use GLUT or SDL, but remember that OpenGL itself always works the same.</p>
+<h2><a class="anchor" id="quick_timer"></a>
+Reading the timer</h2>
+<p>To create smooth animation, a time source is needed. GLFW provides a timer that returns the number of seconds since initialization. The time source used is the most accurate on each platform and generally has micro- or nanosecond resolution.</p>
+<div class="fragment"><div class="line"><span class="keywordtype">double</span> time = <a class="code" href="group__input.html#gaa6cf4e7a77158a3b8fd00328b1720a4a">glfwGetTime</a>();</div>
+</div><!-- fragment --><h2><a class="anchor" id="quick_swap_buffers"></a>
+Swapping buffers</h2>
+<p>GLFW windows by default use double buffering. That means that each window has two rendering buffers; a front buffer and a back buffer. The front buffer is the one being displayed and the back buffer the one you render to.</p>
+<p>When the entire frame has been rendered, the buffers need to be swapped with one another, so the back buffer becomes the front buffer and vice versa.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga15a5a1ee5b3c2ca6b15ca209a12efd14">glfwSwapBuffers</a>(window);</div>
+</div><!-- fragment --><p>The swap interval indicates how many frames to wait until swapping the buffers, commonly known as <em>vsync</em>. By default, the swap interval is zero, meaning buffer swapping will occur immediately. On fast machines, many of those frames will never be seen, as the screen is still only updated typically 60-75 times per second, so this wastes a lot of CPU and GPU cycles.</p>
+<p>Also, because the buffers will be swapped in the middle the screen update, leading to <a href="https://en.wikipedia.org/wiki/Screen_tearing">screen tearing</a>.</p>
+<p>For these reasons, applications will typically want to set the swap interval to one. It can be set to higher values, but this is usually not recommended, because of the input latency it leads to.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__context.html#ga6d4e0cdf151b5e579bd67f13202994ed">glfwSwapInterval</a>(1);</div>
+</div><!-- fragment --><p>This function acts on the current context and will fail unless a context is current.</p>
+<h2><a class="anchor" id="quick_process_events"></a>
+Processing events</h2>
+<p>GLFW needs to communicate regularly with the window system both in order to receive events and to show that the application hasn't locked up. Event processing must be done regularly while you have visible windows and is normally done each frame after buffer swapping.</p>
+<p>There are two methods for processing pending events; polling and waiting. This example will use event polling, which processes only those events that have already been received and then returns immediately.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga37bd57223967b4211d60ca1a0bf3c832">glfwPollEvents</a>();</div>
+</div><!-- fragment --><p>This is the best choice when rendering continually, like most games do. If instead you only need to update your rendering once you have received new input, <a class="el" href="group__window.html#ga554e37d781f0a997656c26b2c56c835e">glfwWaitEvents</a> is a better choice. It waits until at least one event has been received, putting the thread to sleep in the meantime, and then processes all received events. This saves a great deal of CPU cycles and is useful for, for example, many kinds of editing tools.</p>

+Putting it together</h1>
+<p>Now that you know how to initialize GLFW, create a window and poll for keyboard input, it's possible to create a simple program.</p>
+<p>This program creates a 640 by 480 windowed mode window and starts a loop that clears the screen, renders a triangle and processes events until the user either presses <em>Escape</em> or closes the window.</p>

If you built GLFW from the source package then you already have this as <code>simple.exe</code> on Windows, <code>simple</code> on Linux or <code>simple.app</code> on macOS.</p>
+<p>This tutorial used only a few of the many functions GLFW provides. There are guides for each of the areas covered by GLFW. Each guide will introduce all the functions for that category.</p>

+<p>You can access reference documentation for any GLFW function by clicking it and the reference for each function links to related functions and guide sections.</p>
+<p>The tutorial ends here. Once you have written a program that uses GLFW, you will need to compile and link it. How to do that depends on the development environment you are using and is best explained by the documentation for that environment.

It assumes some familiarity with Vulkan concepts like loaders, devices, queues and surfaces and leaves it to the Vulkan documentation to explain the details of Vulkan functions.</p>
+<p>To develop for Vulkan you should download the <a href="https://vulkan.lunarg.com/">LunarG Vulkan SDK</a> for your platform. Apart from headers and link libraries, they also provide the validation layers necessary for development.</p>
+<p>For details on a specific function in this category, see the <a class="el" href="group__vulkan.html">Vulkan reference</a>. There are also guides for the other areas of the GLFW API.</p>

+<h1><a class="anchor" id="vulkan_loader"></a>
+Linking against the Vulkan loader</h1>
+<p>By default, GLFW will look for the Vulkan loader on demand at runtime via its standard name (<code>vulkan-1.dll</code> on Windows, <code>libvulkan.so.1</code> on Linux and other Unix-like systems and <code>libvulkan.1.dylib</code> on macOS). This means that GLFW does not need to be linked against the loader. However, it also means that if you are using the static library form of the Vulkan loader GLFW will either fail to find it or (worse) use the wrong one.</p>
+<p>The <a class="el" href="compile_guide.html#GLFW_VULKAN_STATIC">GLFW_VULKAN_STATIC</a> CMake option makes GLFW call the Vulkan loader directly instead of dynamically loading it at runtime. Not linking against the Vulkan loader will then be a compile-time error.</p>
+<p><b>macOS:</b> Because the Vulkan loader and ICD are not installed globally on macOS, you need to set up the application bundle according to the LunarG SDK documentation. This is explained in more detail in the <a href="https://vulkan.lunarg.com/doc/sdk/latest/mac/getting_started.html">SDK documentation for macOS</a>.</p>
+<h1><a class="anchor" id="vulkan_include"></a>
+Including the Vulkan and GLFW header files</h1>
+<p>To include the Vulkan header, define <a class="el" href="build_guide.html#GLFW_INCLUDE_VULKAN">GLFW_INCLUDE_VULKAN</a> before including the GLFW header.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#define GLFW_INCLUDE_VULKAN</span></div>
+<div class="line"><span class="preprocessor">#include &lt;GLFW/glfw3.h&gt;</span></div>
+</div><!-- fragment --><p>If you instead want to include the Vulkan header from a custom location or use your own custom Vulkan header then do this before the GLFW header.</p>
+<div class="fragment"><div class="line"><span class="preprocessor">#include &lt;path/to/vulkan.h&gt;</span></div>
+<div class="line"><span class="preprocessor">#include &lt;<a class="code" href="glfw3_8h.html">GLFW/glfw3.h</a>&gt;</span></div>
+</div><!-- fragment --><p>Unless a Vulkan header is included, either by the GLFW header or above it, any GLFW functions that take or return Vulkan types will not be declared.</p>
+<p>The <code>VK_USE_PLATFORM_*_KHR</code> macros do not need to be defined for the Vulkan part of GLFW to work. Define them only if you are using these extensions directly.</p>
+<h1><a class="anchor" id="vulkan_support"></a>
+Querying for Vulkan support</h1>
+<p>If you are linking directly against the Vulkan loader then you can skip this section. The canonical desktop loader library exports all Vulkan core and Khronos extension functions, allowing them to be called directly.</p>
+<p>If you are loading the Vulkan loader dynamically instead of linking directly against it, you can check for the availability of a loader and ICD with <a class="el" href="group__vulkan.html#ga2e7f30931e02464b5bc8d0d4b6f9fe2b">glfwVulkanSupported</a>.</p>
+<div class="fragment"><div class="line"><span class="keywordflow">if</span> (<a class="code" href="group__vulkan.html#ga2e7f30931e02464b5bc8d0d4b6f9fe2b">glfwVulkanSupported</a>())</div>
+<div class="line">{</div>
+<div class="line">    <span class="comment">// Vulkan is available, at least for compute</span></div>
+<div class="line">}</div>
+</div><!-- fragment --><p>This function returns <code>GLFW_TRUE</code> if the Vulkan loader and any minimally functional ICD was found.</p>
+<p>If if one or both were not found, calling any other Vulkan related GLFW function will generate a <a class="el" href="group__errors.html#ga56882b290db23261cc6c053c40c2d08e">GLFW_API_UNAVAILABLE</a> error.</p>
+<h2><a class="anchor" id="vulkan_proc"></a>
+Querying Vulkan function pointers</h2>
+<p>To load any Vulkan core or extension function from the found loader, call <a class="el" href="group__vulkan.html#gadf228fac94c5fd8f12423ec9af9ff1e9">glfwGetInstanceProcAddress</a>. To load functions needed for instance creation, pass <code>NULL</code> as the instance.</p>
+<div class="fragment"><div class="line">PFN_vkCreateInstance pfnCreateInstance = (PFN_vkCreateInstance)</div>
+<div class="line">    <a class="code" href="group__vulkan.html#gadf228fac94c5fd8f12423ec9af9ff1e9">glfwGetInstanceProcAddress</a>(NULL, <span class="stringliteral">&quot;vkCreateInstance&quot;</span>);</div>
+</div><!-- fragment --><p>Once you have created an instance, you can load from it all other Vulkan core functions and functions from any instance extensions you enabled.</p>
+<div class="fragment"><div class="line">PFN_vkCreateDevice pfnCreateDevice = (PFN_vkCreateDevice)</div>
+<div class="line">    <a class="code" href="group__vulkan.html#gadf228fac94c5fd8f12423ec9af9ff1e9">glfwGetInstanceProcAddress</a>(instance, <span class="stringliteral">&quot;vkCreateDevice&quot;</span>);</div>
+</div><!-- fragment --><p>This function in turn calls <code>vkGetInstanceProcAddr</code>. If that fails, the function falls back to a platform-specific query of the Vulkan loader (i.e. <code>dlsym</code> or <code>GetProcAddress</code>). If that also fails, the function returns <code>NULL</code>. For more information about <code>vkGetInstanceProcAddr</code>, see the Vulkan documentation.</p>
+<p>Vulkan also provides <code>vkGetDeviceProcAddr</code> for loading device-specific versions of Vulkan function. This function can be retrieved from an instance with <a class="el" href="group__vulkan.html#gadf228fac94c5fd8f12423ec9af9ff1e9">glfwGetInstanceProcAddress</a>.</p>
+<div class="fragment"><div class="line">PFN_vkGetDeviceProcAddr pfnGetDeviceProcAddr = (PFN_vkGetDeviceProcAddr)</div>
+<div class="line">    <a class="code" href="group__vulkan.html#gadf228fac94c5fd8f12423ec9af9ff1e9">glfwGetInstanceProcAddress</a>(instance, <span class="stringliteral">&quot;vkGetDeviceProcAddr&quot;</span>);</div>
+</div><!-- fragment --><p>Device-specific functions may execute a little bit faster, due to not having to dispatch internally based on the device passed to them. For more information about <code>vkGetDeviceProcAddr</code>, see the Vulkan documentation.</p>
+<h1><a class="anchor" id="vulkan_ext"></a>
+Querying required Vulkan extensions</h1>
+<p>To do anything useful with Vulkan you need to create an instance. If you want to use Vulkan to render to a window, you must enable the instance extensions GLFW requires to create Vulkan surfaces.</p>
+<p>To query the instance extensions required, call <a class="el" href="group__vulkan.html#ga1abcbe61033958f22f63ef82008874b1">glfwGetRequiredInstanceExtensions</a>.</p>
+<div class="fragment"><div class="line">uint32_t count;</div>
+<div class="line"><span class="keyword">const</span> <span class="keywordtype">char</span>** extensions = <a class="code" href="group__vulkan.html#ga1abcbe61033958f22f63ef82008874b1">glfwGetRequiredInstanceExtensions</a>(&amp;count);</div>
+</div><!-- fragment --><p>These extensions must all be enabled when creating instances that are going to be passed to <a class="el" href="group__vulkan.html#gaff3823355cdd7e2f3f9f4d9ea9518d92">glfwGetPhysicalDevicePresentationSupport</a> and <a class="el" href="group__vulkan.html#ga1a24536bec3f80b08ead18e28e6ae965">glfwCreateWindowSurface</a>. The set of extensions will vary depending on platform and may also vary depending on graphics drivers and other factors.</p>
+<p>If it fails it will return <code>NULL</code> and GLFW will not be able to create Vulkan window surfaces. You can still use Vulkan for off-screen rendering and compute work.</p>
+<p>If successful the returned array will always include <code>VK_KHR_surface</code>, so if you don't require any additional extensions you can pass this list directly to the <code>VkInstanceCreateInfo</code> struct.</p>
+<div class="fragment"><div class="line">VkInstanceCreateInfo ici;</div>
+<div class="line"> </div>
+<div class="line">memset(&amp;ici, 0, <span class="keyword">sizeof</span>(ici));</div>
+<div class="line">ici.enabledExtensionCount = count;</div>
+<div class="line">ici.ppEnabledExtensionNames = extensions;</div>
+<div class="line">...</div>
+</div><!-- fragment --><p>Additional extensions may be required by future versions of GLFW. You should check whether any extensions you wish to enable are already in the returned array, as it is an error to specify an extension more than once in the <code>VkInstanceCreateInfo</code> struct.</p>
+<h1><a class="anchor" id="vulkan_present"></a>
+Querying for Vulkan presentation support</h1>
+<p>Not every queue family of every Vulkan device can present images to surfaces. To check whether a specific queue family of a physical device supports image presentation without first having to create a window and surface, call <a class="el" href="group__vulkan.html#gaff3823355cdd7e2f3f9f4d9ea9518d92">glfwGetPhysicalDevicePresentationSupport</a>.</p>
+<div class="fragment"><div class="line"><span class="keywordflow">if</span> (<a class="code" href="group__vulkan.html#gaff3823355cdd7e2f3f9f4d9ea9518d92">glfwGetPhysicalDevicePresentationSupport</a>(instance, physical_device, queue_family_index))</div>
+<div class="line">{</div>
+<div class="line">    <span class="comment">// Queue family supports image presentation</span></div>
+<div class="line">}</div>
+</div><!-- fragment --><p>The <code>VK_KHR_surface</code> extension additionally provides the <code>vkGetPhysicalDeviceSurfaceSupportKHR</code> function, which performs the same test on an existing Vulkan surface.</p>
+<h1><a class="anchor" id="vulkan_window"></a>
+Creating the window</h1>

+Window objects</h1>
+<p>The <a class="el" href="group__window.html#ga3c96d80d363e67d13a41b5d1821f3242">GLFWwindow</a> object encapsulates both a window and a context. They are created with <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a> and destroyed with <a class="el" href="group__window.html#gacdf43e51376051d2c091662e9fe3d7b2">glfwDestroyWindow</a>, or <a class="el" href="group__init.html#gaaae48c0a18607ea4a4ba951d939f0901">glfwTerminate</a>, if any remain. As the window and context are inseparably linked, the object pointer is used as both a context and window handle.</p>
+<p>To see the event stream provided to the various window related callbacks, run the <code>events</code> test program.</p>
+<h2><a class="anchor" id="window_creation"></a>
+Window creation</h2>
+<p>A window and its OpenGL or OpenGL ES context are created with <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>, which returns a handle to the created window object. For example, this creates a 640 by 480 windowed mode window:</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga3c96d80d363e67d13a41b5d1821f3242">GLFWwindow</a>* window = <a class="code" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>(640, 480, <span class="stringliteral">&quot;My Title&quot;</span>, NULL, NULL);</div>
+</div><!-- fragment --><p>If window creation fails, <code>NULL</code> will be returned, so it is necessary to check the return value.</p>
+<p>The window handle is passed to all window related functions and is provided to along with all input events, so event handlers can tell which window received the event.</p>
+<h3><a class="anchor" id="window_full_screen"></a>
+Full screen windows</h3>
+<p>To create a full screen window, you need to specify which monitor the window should use. In most cases, the user's primary monitor is a good choice. For more information about retrieving monitors, see <a class="el" href="monitor_guide.html#monitor_monitors">Retrieving monitors</a>.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga3c96d80d363e67d13a41b5d1821f3242">GLFWwindow</a>* window = <a class="code" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>(640, 480, <span class="stringliteral">&quot;My Title&quot;</span>, <a class="code" href="group__monitor.html#ga721867d84c6d18d6790d64d2847ca0b1">glfwGetPrimaryMonitor</a>(), NULL);</div>
+</div><!-- fragment --><p>Full screen windows cover the entire display area of a monitor, have no border or decorations.</p>

+<p>Each field of the <a class="el" href="structGLFWvidmode.html">GLFWvidmode</a> structure corresponds to a function parameter or window hint and combine to form the <em>desired video mode</em> for that window.

+<p>Once you have a full screen window, you can change its resolution, refresh rate and monitor with <a class="el" href="group__window.html#ga81c76c418af80a1cce7055bccb0ae0a7">glfwSetWindowMonitor</a>. If you only need change its resolution you can also call <a class="el" href="group__window.html#ga371911f12c74c504dd8d47d832d095cb">glfwSetWindowSize</a>. In all cases, the new video mode will be selected the same way as the video mode chosen by <a class="el" href="group__window.html#ga5c336fddf2cbb5b92f65f10fb6043344">glfwCreateWindow</a>. If the window has an OpenGL or OpenGL ES context, it will be unaffected.</p>
+<p>By default, the original video mode of the monitor will be restored and the window iconified if it loses input focus, to allow the user to switch back to the desktop. This behavior can be disabled with the <a class="el" href="window_guide.html#GLFW_AUTO_ICONIFY_hint">GLFW_AUTO_ICONIFY</a> window hint, for example if you wish to simultaneously cover multiple monitors with full screen windows.</p>
+<p>If a monitor is disconnected, all windows that are full screen on that monitor will be switched to windowed mode. See <a class="el" href="monitor_guide.html#monitor_event">Monitor configuration changes</a> for more information.</p>

+<p>If the closest match for the desired video mode is the current one, the video mode will not be changed, making window creation faster and application switching much smoother. This is sometimes called <em>windowed full screen</em> or <em>borderless full screen</em> window and counts as a full screen window. To create such a window, request the current video mode.</p>

+Window creation hints</h2>
+<p>There are a number of hints that can be set before the creation of a window and context. Some affect the window itself, others affect the framebuffer or context. These hints are set to their default values each time the library is initialized with <a class="el" href="group__init.html#ga317aac130a235ab08c6db0834907d85e">glfwInit</a>. Integer value hints can be set individually with <a class="el" href="group__window.html#ga7d9c8c62384b1e2821c4dc48952d2033">glfwWindowHint</a> and string value hints with <a class="el" href="group__window.html#ga8cb2782861c9d997bcf2dea97f363e5f">glfwWindowHintString</a>.

This relies on the system DPI and scaling settings being somewhat correct.</p>
+<p>On systems where each monitors can have its own content scale, the window content scale will depend on which monitor the system considers the window to be on.</p>

+Framebuffer related attributes</h3>
+<p>GLFW does not expose attributes of the default framebuffer (i.e. the framebuffer attached to the window) as these can be queried directly with either OpenGL, OpenGL ES or Vulkan.</p>
+<p>If you are using version 3.0 or later of OpenGL or OpenGL ES, the <code>glGetFramebufferAttachmentParameteriv</code> function can be used to retrieve the number of bits for the red, green, blue, alpha, depth and stencil buffer channels. Otherwise, the <code>glGetIntegerv</code> function can be used.</p>
+<p>The number of MSAA samples are always retrieved with <code>glGetIntegerv</code>. For contexts supporting framebuffer objects, the number of samples of the currently bound framebuffer is returned.</p>

+<h1><a class="anchor" id="buffer_swap"></a>
+Buffer swapping</h1>
+<p>GLFW windows are by default double buffered. That means that you have two rendering buffers; a front buffer and a back buffer. The front buffer is the one being displayed and the back buffer the one you render to.</p>
+<p>When the entire frame has been rendered, it is time to swap the back and the front buffers in order to display what has been rendered and begin rendering a new frame. This is done with <a class="el" href="group__window.html#ga15a5a1ee5b3c2ca6b15ca209a12efd14">glfwSwapBuffers</a>.</p>
+<div class="fragment"><div class="line"><a class="code" href="group__window.html#ga15a5a1ee5b3c2ca6b15ca209a12efd14">glfwSwapBuffers</a>(window);</div>
+</div><!-- fragment --><p>Sometimes it can be useful to select when the buffer swap will occur. With the function <a class="el" href="group__context.html#ga6d4e0cdf151b5e579bd67f13202994ed">glfwSwapInterval</a> it is possible to select the minimum number of monitor refreshes the driver should wait from the time <a class="el" href="group__window.html#ga15a5a1ee5b3c2ca6b15ca209a12efd14">glfwSwapBuffers</a> was called before swapping the buffers:</p>
+<div class="fragment"><div class="line"><a class="code" href="group__context.html#ga6d4e0cdf151b5e579bd67f13202994ed">glfwSwapInterval</a>(1);</div>
+</div><!-- fragment --><p>If the interval is zero, the swap will take place immediately when <a class="el" href="group__window.html#ga15a5a1ee5b3c2ca6b15ca209a12efd14">glfwSwapBuffers</a> is called without waiting for a refresh. Otherwise at least interval retraces will pass between each buffer swap. Using a swap interval of zero can be useful for benchmarking purposes, when it is not desirable to measure the time it takes to wait for the vertical retrace. However, a swap interval of one lets you avoid tearing.</p>
+<p>Note that this may not work on all machines, as some drivers have user-controlled settings that override any swap interval the application requests.</p>
+<p>A context that supports either the <code>WGL_EXT_swap_control_tear</code> or the <code>GLX_EXT_swap_control_tear</code> extension also accepts <em>negative</em> swap intervals, which allows the driver to swap immediately even if a frame arrives a little bit late. This trades the risk of visible tears for greater framerate stability. You can check for these extensions with <a class="el" href="group__context.html#ga87425065c011cef1ebd6aac75e059dfa">glfwExtensionSupported</a>. </p>

+@page input_guide Input guide
+
+@tableofcontents
+
+This guide introduces the input related functions of GLFW.  For details on
+a specific function in this category, see the @ref input.  There are also guides
+for the other areas of GLFW.
+
+ - @ref intro_guide
+ - @ref window_guide
+ - @ref context_guide
+ - @ref vulkan_guide
+ - @ref monitor_guide
+
+GLFW provides many kinds of input.  While some can only be polled, like time, or
+only received via callbacks, like scrolling, many provide both callbacks and
+polling.  Callbacks are more work to use than polling but is less CPU intensive
+and guarantees that you do not miss state changes.
+
+All input callbacks receive a window handle.  By using the
+[window user pointer](@ref window_userptr), you can access non-global structures
+or objects from your callbacks.
+
+To get a better feel for how the various events callbacks behave, run the
+`events` test program.  It register every callback supported by GLFW and prints
+out all arguments provided for every event, along with time and sequence
+information.
+
+
+@section events Event processing
+
+GLFW needs to poll the window system for events both to provide input to the
+application and to prove to the window system that the application hasn't locked
+up.  Event processing is normally done each frame after
+[buffer swapping](@ref buffer_swap).  Even when you have no windows, event
+polling needs to be done in order to receive monitor and joystick connection
+events.
+
+There are three functions for processing pending events.  @ref glfwPollEvents,
+processes only those events that have already been received and then returns
+immediately.
+
+@code
+glfwPollEvents();
+@endcode
+
+This is the best choice when rendering continuously, like most games do.
+
+If you only need to update the contents of the window when you receive new
+input, @ref glfwWaitEvents is a better choice.
+
+@code
+glfwWaitEvents();
+@endcode
+
+It puts the thread to sleep until at least one event has been received and then
+processes all received events.  This saves a great deal of CPU cycles and is
+useful for, for example, editing tools.
+
+If you want to wait for events but have UI elements or other tasks that need
+periodic updates, @ref glfwWaitEventsTimeout lets you specify a timeout.
+
+@code
+glfwWaitEventsTimeout(0.7);
+@endcode
+
+It puts the thread to sleep until at least one event has been received, or until
+the specified number of seconds have elapsed.  It then processes any received
+events.
+
+If the main thread is sleeping in @ref glfwWaitEvents, you can wake it from
+another thread by posting an empty event to the event queue with @ref
+glfwPostEmptyEvent.
+
+@code
+glfwPostEmptyEvent();
+@endcode
+
+Do not assume that callbacks will _only_ be called in response to the above
+functions.  While it is necessary to process events in one or more of the ways
+above, window systems that require GLFW to register callbacks of its own can
+pass events to GLFW in response to many window system function calls.  GLFW will
+pass those events on to the application callbacks before returning.
+
+For example, on Windows the system function that @ref glfwSetWindowSize is
+implemented with will send window size events directly to the event callback
+that every window has and that GLFW implements for its windows.  If you have set
+a [window size callback](@ref window_size) GLFW will call it in turn with the
+new size before everything returns back out of the @ref glfwSetWindowSize call.
+
+
+@section input_keyboard Keyboard input
+
+GLFW divides keyboard input into two categories; key events and character
+events.  Key events relate to actual physical keyboard keys, whereas character
+events relate to the Unicode code points generated by pressing some of them.
+
+Keys and characters do not map 1:1.  A single key press may produce several
+characters, and a single character may require several keys to produce.  This
+may not be the case on your machine, but your users are likely not all using the
+same keyboard layout, input method or even operating system as you.
+
+
+@subsection input_key Key input
+
+If you wish to be notified when a physical key is pressed or released or when it
+repeats, set a key callback.
+
+@code
+glfwSetKeyCallback(window, key_callback);
+@endcode
+
+The callback function receives the [keyboard key](@ref keys), platform-specific
+scancode, key action and [modifier bits](@ref mods).
+
+@code
+void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods)
+{
+    if (key == GLFW_KEY_E && action == GLFW_PRESS)
+        activate_airship();
+}
+@endcode
+
+The action is one of `GLFW_PRESS`, `GLFW_REPEAT` or `GLFW_RELEASE`.  The key
+will be `GLFW_KEY_UNKNOWN` if GLFW lacks a key token for it, for example
+_E-mail_ and _Play_ keys.
+
+The scancode is unique for every key, regardless of whether it has a key token.
+Scancodes are platform-specific but consistent over time, so keys will have
+different scancodes depending on the platform but they are safe to save to disk.
+You can query the scancode for any [named key](@ref keys) on the current
+platform with @ref glfwGetKeyScancode.
+
+@code
+const int scancode = glfwGetKeyScancode(GLFW_KEY_X);
+set_key_mapping(scancode, swap_weapons);
+@endcode
+
+The last reported state for every [named key](@ref keys) is also saved in
+per-window state arrays that can be polled with @ref glfwGetKey.
+
+@code
+int state = glfwGetKey(window, GLFW_KEY_E);
+if (state == GLFW_PRESS)
+{
+    activate_airship();
+}
+@endcode
+
+The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`.
+
+This function only returns cached key event state.  It does not poll the
+system for the current physical state of the key.
+
+@anchor GLFW_STICKY_KEYS
+Whenever you poll state, you risk missing the state change you are looking for.
+If a pressed key is released again before you poll its state, you will have
+missed the key press.  The recommended solution for this is to use a
+key callback, but there is also the `GLFW_STICKY_KEYS` input mode.
+
+@code
+glfwSetInputMode(window, GLFW_STICKY_KEYS, GLFW_TRUE);
+@endcode
+
+When sticky keys mode is enabled, the pollable state of a key will remain
+`GLFW_PRESS` until the state of that key is polled with @ref glfwGetKey.  Once
+it has been polled, if a key release event had been processed in the meantime,
+the state will reset to `GLFW_RELEASE`, otherwise it will remain `GLFW_PRESS`.
+
+@anchor GLFW_LOCK_KEY_MODS
+If you wish to know what the state of the Caps Lock and Num Lock keys was when
+input events were generated, set the `GLFW_LOCK_KEY_MODS` input mode.
+
+@code
+glfwSetInputMode(window, GLFW_LOCK_KEY_MODS, GLFW_TRUE);
+@endcode
+
+When this input mode is enabled, any callback that receives
+[modifier bits](@ref mods) will have the @ref GLFW_MOD_CAPS_LOCK bit set if Caps
+Lock was on when the event occurred and the @ref GLFW_MOD_NUM_LOCK bit set if
+Num Lock was on.
+
+The `GLFW_KEY_LAST` constant holds the highest value of any
+[named key](@ref keys).
+
+
+@subsection input_char Text input
+
+GLFW supports text input in the form of a stream of
+[Unicode code points](https://en.wikipedia.org/wiki/Unicode), as produced by the
+operating system text input system.  Unlike key input, text input obeys keyboard
+layouts and modifier keys and supports composing characters using
+[dead keys](https://en.wikipedia.org/wiki/Dead_key).  Once received, you can
+encode the code points into UTF-8 or any other encoding you prefer.
+
+Because an `unsigned int` is 32 bits long on all platforms supported by GLFW,
+you can treat the code point argument as native endian UTF-32.
+
+If you wish to offer regular text input, set a character callback.
+
+@code
+glfwSetCharCallback(window, character_callback);
+@endcode
+
+The callback function receives Unicode code points for key events that would
+have led to regular text input and generally behaves as a standard text field on
+that platform.
+
+@code
+void character_callback(GLFWwindow* window, unsigned int codepoint)
+{
+}
+@endcode
+
+
+@subsection input_key_name Key names
+
+If you wish to refer to keys by name, you can query the keyboard layout
+dependent name of printable keys with @ref glfwGetKeyName.
+
+@code
+const char* key_name = glfwGetKeyName(GLFW_KEY_W, 0);
+show_tutorial_hint("Press %s to move forward", key_name);
+@endcode
+
+This function can handle both [keys and scancodes](@ref input_key).  If the
+specified key is `GLFW_KEY_UNKNOWN` then the scancode is used, otherwise it is
+ignored.  This matches the behavior of the key callback, meaning the callback
+arguments can always be passed unmodified to this function.
+
+
+@section input_mouse Mouse input
+
+Mouse input comes in many forms, including mouse motion, button presses and
+scrolling offsets.  The cursor appearance can also be changed, either to
+a custom image or a standard cursor shape from the system theme.
+
+
+@subsection cursor_pos Cursor position
+
+If you wish to be notified when the cursor moves over the window, set a cursor
+position callback.
+
+@code
+glfwSetCursorPosCallback(window, cursor_position_callback);
+@endcode
+
+The callback functions receives the cursor position, measured in screen
+coordinates but relative to the top-left corner of the window content area.  On
+platforms that provide it, the full sub-pixel cursor position is passed on.
+
+@code
+static void cursor_position_callback(GLFWwindow* window, double xpos, double ypos)
+{
+}
+@endcode
+
+The cursor position is also saved per-window and can be polled with @ref
+glfwGetCursorPos.
+
+@code
+double xpos, ypos;
+glfwGetCursorPos(window, &xpos, &ypos);
+@endcode
+
+
+@subsection cursor_mode Cursor mode
+
+@anchor GLFW_CURSOR
+The `GLFW_CURSOR` input mode provides several cursor modes for special forms of
+mouse motion input.  By default, the cursor mode is `GLFW_CURSOR_NORMAL`,
+meaning the regular arrow cursor (or another cursor set with @ref glfwSetCursor)
+is used and cursor motion is not limited.
+
+If you wish to implement mouse motion based camera controls or other input
+schemes that require unlimited mouse movement, set the cursor mode to
+`GLFW_CURSOR_DISABLED`.
+
+@code
+glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED);
+@endcode
+
+This will hide the cursor and lock it to the specified window.  GLFW will then
+take care of all the details of cursor re-centering and offset calculation and
+providing the application with a virtual cursor position.  This virtual position
+is provided normally via both the cursor position callback and through polling.
+
+@note You should not implement your own version of this functionality using
+other features of GLFW.  It is not supported and will not work as robustly as
+`GLFW_CURSOR_DISABLED`.
+
+If you only wish the cursor to become hidden when it is over a window but still
+want it to behave normally, set the cursor mode to `GLFW_CURSOR_HIDDEN`.
+
+@code
+glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_HIDDEN);
+@endcode
+
+This mode puts no limit on the motion of the cursor.
+
+To exit out of either of these special modes, restore the `GLFW_CURSOR_NORMAL`
+cursor mode.
+
+@code
+glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_NORMAL);
+@endcode
+
+
+@anchor GLFW_RAW_MOUSE_MOTION
+@subsection raw_mouse_motion Raw mouse motion
+
+When the cursor is disabled, raw (unscaled and unaccelerated) mouse motion can
+be enabled if available.
+
+Raw mouse motion is closer to the actual motion of the mouse across a surface.
+It is not affected by the scaling and acceleration applied to the motion of the
+desktop cursor.  That processing is suitable for a cursor while raw motion is
+better for controlling for example a 3D camera.  Because of this, raw mouse
+motion is only provided when the cursor is disabled.
+
+Call @ref glfwRawMouseMotionSupported to check if the current machine provides
+raw motion and set the `GLFW_RAW_MOUSE_MOTION` input mode to enable it.  It is
+disabled by default.
+
+@code
+if (glfwRawMouseMotionSupported())
+    glfwSetInputMode(window, GLFW_RAW_MOUSE_MOTION, GLFW_TRUE);
+@endcode
+
+If supported, raw mouse motion can be enabled or disabled per-window and at any
+time but it will only be provided when the cursor is disabled.
+
+
+@subsection cursor_object Cursor objects
+
+GLFW supports creating both custom and system theme cursor images, encapsulated
+as @ref GLFWcursor objects.  They are created with @ref glfwCreateCursor or @ref
+glfwCreateStandardCursor and destroyed with @ref glfwDestroyCursor, or @ref
+glfwTerminate, if any remain.
+
+
+@subsubsection cursor_custom Custom cursor creation
+
+A custom cursor is created with @ref glfwCreateCursor, which returns a handle to
+the created cursor object.  For example, this creates a 16x16 white square
+cursor with the hot-spot in the upper-left corner:
+
+@code
+unsigned char pixels[16 * 16 * 4];
+memset(pixels, 0xff, sizeof(pixels));
+
+GLFWimage image;
+image.width = 16;
+image.height = 16;
+image.pixels = pixels;
+
+GLFWcursor* cursor = glfwCreateCursor(&image, 0, 0);
+@endcode
+
+If cursor creation fails, `NULL` will be returned, so it is necessary to check
+the return value.
+
+The image data is 32-bit, little-endian, non-premultiplied RGBA, i.e. eight bits
+per channel with the red channel first.  The pixels are arranged canonically as
+sequential rows, starting from the top-left corner.
+
+
+@subsubsection cursor_standard Standard cursor creation
+
+A cursor with a [standard shape](@ref shapes) from the current system cursor
+theme can be can be created with @ref glfwCreateStandardCursor.
+
+@code
+GLFWcursor* cursor = glfwCreateStandardCursor(GLFW_HRESIZE_CURSOR);
+@endcode
+
+These cursor objects behave in the exact same way as those created with @ref
+glfwCreateCursor except that the system cursor theme provides the actual image.
+
+
+@subsubsection cursor_destruction Cursor destruction
+
+When a cursor is no longer needed, destroy it with @ref glfwDestroyCursor.
+
+@code
+glfwDestroyCursor(cursor);
+@endcode
+
+Cursor destruction always succeeds.  If the cursor is current for any window,
+that window will revert to the default cursor.  This does not affect the cursor
+mode.  All remaining cursors are destroyed when @ref glfwTerminate is called.
+
+
+@subsubsection cursor_set Cursor setting
+
+A cursor can be set as current for a window with @ref glfwSetCursor.
+
+@code
+glfwSetCursor(window, cursor);
+@endcode
+
+Once set, the cursor image will be used as long as the system cursor is over the
+content area of the window and the [cursor mode](@ref cursor_mode) is set
+to `GLFW_CURSOR_NORMAL`.
+
+A single cursor may be set for any number of windows.
+
+To revert to the default cursor, set the cursor of that window to `NULL`.
+
+@code
+glfwSetCursor(window, NULL);
+@endcode
+
+When a cursor is destroyed, any window that has it set will revert to the
+default cursor.  This does not affect the cursor mode.
+
+
+@subsection cursor_enter Cursor enter/leave events
+
+If you wish to be notified when the cursor enters or leaves the content area of
+a window, set a cursor enter/leave callback.
+
+@code
+glfwSetCursorEnterCallback(window, cursor_enter_callback);
+@endcode
+
+The callback function receives the new classification of the cursor.
+
+@code
+void cursor_enter_callback(GLFWwindow* window, int entered)
+{
+    if (entered)
+    {
+        // The cursor entered the content area of the window
+    }
+    else
+    {
+        // The cursor left the content area of the window
+    }
+}
+@endcode
+
+You can query whether the cursor is currently inside the content area of the
+window with the [GLFW_HOVERED](@ref GLFW_HOVERED_attrib) window attribute.
+
+@code
+if (glfwGetWindowAttrib(window, GLFW_HOVERED))
+{
+    highlight_interface();
+}
+@endcode
+
+
+@subsection input_mouse_button Mouse button input
+
+If you wish to be notified when a mouse button is pressed or released, set
+a mouse button callback.
+
+@code
+glfwSetMouseButtonCallback(window, mouse_button_callback);
+@endcode
+
+The callback function receives the [mouse button](@ref buttons), button action
+and [modifier bits](@ref mods).
+
+@code
+void mouse_button_callback(GLFWwindow* window, int button, int action, int mods)
+{
+    if (button == GLFW_MOUSE_BUTTON_RIGHT && action == GLFW_PRESS)
+        popup_menu();
+}
+@endcode
+
+The action is one of `GLFW_PRESS` or `GLFW_RELEASE`.
+
+Mouse button states for [named buttons](@ref buttons) are also saved in
+per-window state arrays that can be polled with @ref glfwGetMouseButton.
+
+@code
+int state = glfwGetMouseButton(window, GLFW_MOUSE_BUTTON_LEFT);
+if (state == GLFW_PRESS)
+{
+    upgrade_cow();
+}
+@endcode
+
+The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`.
+
+This function only returns cached mouse button event state.  It does not poll
+the system for the current state of the mouse button.
+
+@anchor GLFW_STICKY_MOUSE_BUTTONS
+Whenever you poll state, you risk missing the state change you are looking for.
+If a pressed mouse button is released again before you poll its state, you will have
+missed the button press.  The recommended solution for this is to use a
+mouse button callback, but there is also the `GLFW_STICKY_MOUSE_BUTTONS`
+input mode.
+
+@code
+glfwSetInputMode(window, GLFW_STICKY_MOUSE_BUTTONS, GLFW_TRUE);
+@endcode
+
+When sticky mouse buttons mode is enabled, the pollable state of a mouse button
+will remain `GLFW_PRESS` until the state of that button is polled with @ref
+glfwGetMouseButton.  Once it has been polled, if a mouse button release event
+had been processed in the meantime, the state will reset to `GLFW_RELEASE`,
+otherwise it will remain `GLFW_PRESS`.
+
+The `GLFW_MOUSE_BUTTON_LAST` constant holds the highest value of any
+[named button](@ref buttons).
+
+
+@subsection scrolling Scroll input
+
+If you wish to be notified when the user scrolls, whether with a mouse wheel or
+touchpad gesture, set a scroll callback.
+
+@code
+glfwSetScrollCallback(window, scroll_callback);
+@endcode
+
+The callback function receives two-dimensional scroll offsets.
+
+@code
+void scroll_callback(GLFWwindow* window, double xoffset, double yoffset)
+{
+}
+@endcode
+
+A normal mouse wheel, being vertical, provides offsets along the Y-axis.
+
+
+@section joystick Joystick input
+
+The joystick functions expose connected joysticks and controllers, with both
+referred to as joysticks.  It supports up to sixteen joysticks, ranging from
+`GLFW_JOYSTICK_1`, `GLFW_JOYSTICK_2` up to and including `GLFW_JOYSTICK_16` or
+`GLFW_JOYSTICK_LAST`.  You can test whether a [joystick](@ref joysticks) is
+present with @ref glfwJoystickPresent.
+
+@code
+int present = glfwJoystickPresent(GLFW_JOYSTICK_1);
+@endcode
+
+Each joystick has zero or more axes, zero or more buttons, zero or more hats,
+a human-readable name, a user pointer and an SDL compatible GUID.
+
+When GLFW is initialized, detected joysticks are added to the beginning of
+the array.  Once a joystick is detected, it keeps its assigned ID until it is
+disconnected or the library is terminated, so as joysticks are connected and
+disconnected, there may appear gaps in the IDs.
+
+Joystick axis, button and hat state is updated when polled and does not require
+a window to be created or events to be processed.  However, if you want joystick
+connection and disconnection events reliably delivered to the
+[joystick callback](@ref joystick_event) then you must
+[process events](@ref events).
+
+To see all the properties of all connected joysticks in real-time, run the
+`joysticks` test program.
+
+
+@subsection joystick_axis Joystick axis states
+
+The positions of all axes of a joystick are returned by @ref
+glfwGetJoystickAxes.  See the reference documentation for the lifetime of the
+returned array.
+
+@code
+int count;
+const float* axes = glfwGetJoystickAxes(GLFW_JOYSTICK_5, &count);
+@endcode
+
+Each element in the returned array is a value between -1.0 and 1.0.
+
+
+@subsection joystick_button Joystick button states
+
+The states of all buttons of a joystick are returned by @ref
+glfwGetJoystickButtons.  See the reference documentation for the lifetime of the
+returned array.
+
+@code
+int count;
+const unsigned char* buttons = glfwGetJoystickButtons(GLFW_JOYSTICK_3, &count);
+@endcode
+
+Each element in the returned array is either `GLFW_PRESS` or `GLFW_RELEASE`.
+
+For backward compatibility with earlier versions that did not have @ref
+glfwGetJoystickHats, the button array by default also includes all hats.  See
+the reference documentation for @ref glfwGetJoystickButtons for details.
+
+
+@subsection joystick_hat Joystick hat states
+
+The states of all hats are returned by @ref glfwGetJoystickHats.  See the
+reference documentation for the lifetime of the returned array.
+
+@code
+int count;
+const unsigned char* hats = glfwGetJoystickHats(GLFW_JOYSTICK_7, &count);
+@endcode
+
+Each element in the returned array is one of the following:
+
+Name                  | Value
+----                  | -----
+`GLFW_HAT_CENTERED`   | 0
+`GLFW_HAT_UP`         | 1
+`GLFW_HAT_RIGHT`      | 2
+`GLFW_HAT_DOWN`       | 4
+`GLFW_HAT_LEFT`       | 8
+`GLFW_HAT_RIGHT_UP`   | `GLFW_HAT_RIGHT` \| `GLFW_HAT_UP`
+`GLFW_HAT_RIGHT_DOWN` | `GLFW_HAT_RIGHT` \| `GLFW_HAT_DOWN`
+`GLFW_HAT_LEFT_UP`    | `GLFW_HAT_LEFT` \| `GLFW_HAT_UP`
+`GLFW_HAT_LEFT_DOWN`  | `GLFW_HAT_LEFT` \| `GLFW_HAT_DOWN`
+
+The diagonal directions are bitwise combinations of the primary (up, right, down
+and left) directions and you can test for these individually by ANDing it with
+the corresponding direction.
+
+@code
+if (hats[2] & GLFW_HAT_RIGHT)
+{
+    // State of hat 2 could be right-up, right or right-down
+}
+@endcode
+
+For backward compatibility with earlier versions that did not have @ref
+glfwGetJoystickHats, all hats are by default also included in the button array.
+See the reference documentation for @ref glfwGetJoystickButtons for details.
+
+
+@subsection joystick_name Joystick name
+
+The human-readable, UTF-8 encoded name of a joystick is returned by @ref
+glfwGetJoystickName.  See the reference documentation for the lifetime of the
+returned string.
+
+@code
+const char* name = glfwGetJoystickName(GLFW_JOYSTICK_4);
+@endcode
+
+Joystick names are not guaranteed to be unique.  Two joysticks of the same model
+and make may have the same name.  Only the [joystick token](@ref joysticks) is
+guaranteed to be unique, and only until that joystick is disconnected.
+
+
+@subsection joystick_userptr Joystick user pointer
+
+Each joystick has a user pointer that can be set with @ref
+glfwSetJoystickUserPointer and queried with @ref glfwGetJoystickUserPointer.
+This can be used for any purpose you need and will not be modified by GLFW.  The
+value will be kept until the joystick is disconnected or until the library is
+terminated.
+
+The initial value of the pointer is `NULL`.
+
+
+@subsection joystick_event Joystick configuration changes
+
+If you wish to be notified when a joystick is connected or disconnected, set
+a joystick callback.
+
+@code
+glfwSetJoystickCallback(joystick_callback);
+@endcode
+
+The callback function receives the ID of the joystick that has been connected
+and disconnected and the event that occurred.
+
+@code
+void joystick_callback(int jid, int event)
+{
+    if (event == GLFW_CONNECTED)
+    {
+        // The joystick was connected
+    }
+    else if (event == GLFW_DISCONNECTED)
+    {
+        // The joystick was disconnected
+    }
+}
+@endcode
+
+For joystick connection and disconnection events to be delivered on all
+platforms, you need to call one of the [event processing](@ref events)
+functions.  Joystick disconnection may also be detected and the callback
+called by joystick functions.  The function will then return whatever it
+returns for a disconnected joystick.
+
+Only @ref glfwGetJoystickName and @ref glfwGetJoystickUserPointer will return
+useful values for a disconnected joystick and only before the monitor callback
+returns.
+
+
+@subsection gamepad Gamepad input
+
+The joystick functions provide unlabeled axes, buttons and hats, with no
+indication of where they are located on the device.  Their order may also vary
+between platforms even with the same device.
+
+To solve this problem the SDL community crowdsourced the
+[SDL_GameControllerDB](https://github.com/gabomdq/SDL_GameControllerDB) project,
+a database of mappings from many different devices to an Xbox-like gamepad.
+
+GLFW supports this mapping format and contains a copy of the mappings
+available at the time of release.  See @ref gamepad_mapping for how to update
+this at runtime.  Mappings will be assigned to joysticks automatically any time
+a joystick is connected or the mappings are updated.
+
+You can check whether a joystick is both present and has a gamepad mapping with
+@ref glfwJoystickIsGamepad.
+
+@code
+if (glfwJoystickIsGamepad(GLFW_JOYSTICK_2))
+{
+    // Use as gamepad
+}
+@endcode
+
+If you are only interested in gamepad input you can use this function instead of
+@ref glfwJoystickPresent.
+
+You can query the human-readable name provided by the gamepad mapping with @ref
+glfwGetGamepadName.  This may or may not be the same as the
+[joystick name](@ref joystick_name).
+
+@code
+const char* name = glfwGetGamepadName(GLFW_JOYSTICK_7);
+@endcode
+
+To retrieve the gamepad state of a joystick, call @ref glfwGetGamepadState.
+
+@code
+GLFWgamepadstate state;
+
+if (glfwGetGamepadState(GLFW_JOYSTICK_3, &state))
+{
+    if (state.buttons[GLFW_GAMEPAD_BUTTON_A])
+    {
+        input_jump();
+    }
+
+    input_speed(state.axes[GLFW_GAMEPAD_AXIS_RIGHT_TRIGGER]);
+}
+@endcode
+
+The @ref GLFWgamepadstate struct has two arrays; one for button states and one
+for axis states.  The values for each button and axis are the same as for the
+@ref glfwGetJoystickButtons and @ref glfwGetJoystickAxes functions, i.e.
+`GLFW_PRESS` or `GLFW_RELEASE` for buttons and -1.0 to 1.0 inclusive for axes.
+
+The sizes of the arrays and the positions within each array are fixed.
+
+The [button indices](@ref gamepad_buttons) are `GLFW_GAMEPAD_BUTTON_A`,
+`GLFW_GAMEPAD_BUTTON_B`, `GLFW_GAMEPAD_BUTTON_X`, `GLFW_GAMEPAD_BUTTON_Y`,
+`GLFW_GAMEPAD_BUTTON_LEFT_BUMPER`, `GLFW_GAMEPAD_BUTTON_RIGHT_BUMPER`,
+`GLFW_GAMEPAD_BUTTON_BACK`, `GLFW_GAMEPAD_BUTTON_START`,
+`GLFW_GAMEPAD_BUTTON_GUIDE`, `GLFW_GAMEPAD_BUTTON_LEFT_THUMB`,
+`GLFW_GAMEPAD_BUTTON_RIGHT_THUMB`, `GLFW_GAMEPAD_BUTTON_DPAD_UP`,
+`GLFW_GAMEPAD_BUTTON_DPAD_RIGHT`, `GLFW_GAMEPAD_BUTTON_DPAD_DOWN` and
+`GLFW_GAMEPAD_BUTTON_DPAD_LEFT`.
+
+For those who prefer, there are also the `GLFW_GAMEPAD_BUTTON_CROSS`,
+`GLFW_GAMEPAD_BUTTON_CIRCLE`, `GLFW_GAMEPAD_BUTTON_SQUARE` and
+`GLFW_GAMEPAD_BUTTON_TRIANGLE` aliases for the A, B, X and Y button indices.
+
+The [axis indices](@ref gamepad_axes) are `GLFW_GAMEPAD_AXIS_LEFT_X`,
+`GLFW_GAMEPAD_AXIS_LEFT_Y`, `GLFW_GAMEPAD_AXIS_RIGHT_X`,
+`GLFW_GAMEPAD_AXIS_RIGHT_Y`, `GLFW_GAMEPAD_AXIS_LEFT_TRIGGER` and
+`GLFW_GAMEPAD_AXIS_RIGHT_TRIGGER`.
+
+The `GLFW_GAMEPAD_BUTTON_LAST` and `GLFW_GAMEPAD_AXIS_LAST` constants equal
+the largest available index for each array.
+
+
+@subsection gamepad_mapping Gamepad mappings
+
+GLFW contains a copy of the mappings available in
+[SDL_GameControllerDB](https://github.com/gabomdq/SDL_GameControllerDB) at the
+time of release.  Newer ones can be added at runtime with @ref
+glfwUpdateGamepadMappings.
+
+@code
+const char* mappings = load_file_contents("game/data/gamecontrollerdb.txt");
+
+glfwUpdateGamepadMappings(mappings);
+@endcode
+
+This function supports everything from single lines up to and including the
+unmodified contents of the whole `gamecontrollerdb.txt` file.
+
+Below is a description of the mapping format.  Please keep in mind that __this
+description is not authoritative__.  The format is defined by the SDL and
+SDL_GameControllerDB projects and their documentation and code takes precedence.
+
+Each mapping is a single line of comma-separated values describing the GUID,
+name and layout of the gamepad.  Lines that do not begin with a hexadecimal
+digit are ignored.
+
+The first value is always the gamepad GUID, a 32 character long hexadecimal
+string that typically identifies its make, model, revision and the type of
+connection to the computer.  When this information is not available, the GUID is
+generated using the gamepad name.  GLFW uses the SDL 2.0.5+ GUID format but can
+convert from the older formats.
+
+The second value is always the human-readable name of the gamepad.
+
+All subsequent values are in the form `<field>:<value>` and describe the layout
+of the mapping.  These fields may not all be present and may occur in any order.
+
+The button fields are `a`, `b`, `c`, `d`, `back`, `start`, `guide`, `dpup`,
+`dpright`, `dpdown`, `dpleft`, `leftshoulder`, `rightshoulder`, `leftstick` and
+`rightstick`.
+
+The axis fields are `leftx`, `lefty`, `rightx`, `righty`, `lefttrigger` and
+`righttrigger`.
+
+The value of an axis or button field can be a joystick button, a joystick axis,
+a hat bitmask or empty.  Joystick buttons are specified as `bN`, for example
+`b2` for the third button.  Joystick axes are specified as `aN`, for example
+`a7` for the eighth button.  Joystick hat bit masks are specified as `hN.N`, for
+example `h0.8` for left on the first hat.  More than one bit may be set in the
+mask.
+
+Before an axis there may be a `+` or `-` range modifier, for example `+a3` for
+the positive half of the fourth axis.  This restricts input to only the positive
+or negative halves of the joystick axis.  After an axis or half-axis there may
+be the `~` inversion modifier, for example `a2~` or `-a7~`.  This negates the
+values of the gamepad axis.
+
+The hat bit mask match the [hat states](@ref hat_state) in the joystick
+functions.
+
+There is also the special `platform` field that specifies which platform the
+mapping is valid for.  Possible values are `Windows`, `Mac OS X` and `Linux`.
+
+Below is an example of what a gamepad mapping might look like.  It is the
+one built into GLFW for Xbox controllers accessed via the XInput API on Windows.
+This example has been broken into several lines to fit on the page, but real
+gamepad mappings must be a single line.

+@endcode
+
+@note GLFW does not yet support the output range and modifiers `+` and `-` that
+were recently added to SDL.  The input modifiers `+`, `-` and `~` are supported
+and described above.
+
+
+@section time Time input
+
+GLFW provides high-resolution time input, in seconds, with @ref glfwGetTime.
+
+@code
+double seconds = glfwGetTime();
+@endcode
+
+It returns the number of seconds since the library was initialized with @ref
+glfwInit.  The platform-specific time sources used typically have micro- or
+nanosecond resolution.
+
+You can modify the base time with @ref glfwSetTime.
+
+@code
+glfwSetTime(4.0);
+@endcode
+
+This sets the time to the specified time, in seconds, and it continues to count
+from there.
+
+You can also access the raw timer used to implement the functions above,
+with @ref glfwGetTimerValue.
+
+@code
+uint64_t value = glfwGetTimerValue();
+@endcode
+
+This value is in 1&nbsp;/&nbsp;frequency seconds.  The frequency of the raw
+timer varies depending on the operating system and hardware.  You can query the
+frequency, in Hz, with @ref glfwGetTimerFrequency.
+
+@code
+uint64_t frequency = glfwGetTimerFrequency();
+@endcode
+
+
+@section clipboard Clipboard input and output
+
+If the system clipboard contains a UTF-8 encoded string or if it can be
+converted to one, you can retrieve it with @ref glfwGetClipboardString.  See the
+reference documentation for the lifetime of the returned string.
+
+@code
+const char* text = glfwGetClipboardString(NULL);
+if (text)
+{
+    insert_text(text);
+}
+@endcode
+
+If the clipboard is empty or if its contents could not be converted, `NULL` is
+returned.
+
+The contents of the system clipboard can be set to a UTF-8 encoded string with
+@ref glfwSetClipboardString.
+
+@code
+glfwSetClipboardString(NULL, "A string with words in it");
+@endcode
+
+
+@section path_drop Path drop input
+
+If you wish to receive the paths of files and/or directories dropped on
+a window, set a file drop callback.
+
+@code
+glfwSetDropCallback(window, drop_callback);
+@endcode
+
+The callback function receives an array of paths encoded as UTF-8.
+
+@code
+void drop_callback(GLFWwindow* window, int count, const char** paths)
+{
+    int i;
+    for (i = 0;  i < count;  i++)
+        handle_dropped_file(paths[i]);
+}
+@endcode
+
+The path array and its strings are only valid until the file drop callback
+returns, as they may have been generated specifically for that event.  You need
+to make a deep copy of the array if you want to keep the paths.

+
+@page internals_guide Internal structure
+
+@tableofcontents
+
+There are several interfaces inside GLFW.  Each interface has its own area of
+responsibility and its own naming conventions.
+
+
+@section internals_public Public interface
+
+The most well-known is the public interface, described in the glfw3.h header
+file.  This is implemented in source files shared by all platforms and these
+files contain no platform-specific code.  This code usually ends up calling the
+platform and internal interfaces to do the actual work.
+
+The public interface uses the OpenGL naming conventions except with GLFW and
+glfw instead of GL and gl.  For struct members, where OpenGL sets no precedent,
+it use headless camel case.
+
+Examples: `glfwCreateWindow`, `GLFWwindow`, `GLFW_RED_BITS`
+
+
+@section internals_native Native interface
+
+The [native interface](@ref native) is a small set of publicly available
+but platform-specific functions, described in the glfw3native.h header file and
+used to gain access to the underlying window, context and (on some platforms)
+display handles used by the platform interface.
+
+The function names of the native interface are similar to those of the public
+interface, but embeds the name of the interface that the returned handle is
+from.
+
+Examples: `glfwGetX11Window`, `glfwGetWGLContext`
+
+
+@section internals_internal Internal interface
+
+The internal interface consists of utility functions used by all other
+interfaces.  It is shared code implemented in the same shared source files as
+the public and event interfaces.  The internal interface is described in the
+internal.h header file.
+
+The internal interface is in charge of GLFW's global data, which it stores in
+a `_GLFWlibrary` struct named `_glfw`.
+
+The internal interface uses the same style as the public interface, except all
+global names have a leading underscore.
+
+Examples: `_glfwIsValidContextConfig`, `_GLFWwindow`, `_glfw.monitorCount`
+
+
+@section internals_platform Platform interface
+
+The platform interface implements all platform-specific operations as a service
+to the public interface.  This includes event processing.  The platform
+interface is never directly called by application code and never directly calls
+application-provided callbacks.  It is also prohibited from modifying the
+platform-independent part of the internal structs.  Instead, it calls the event
+interface when events interesting to GLFW are received.
+
+The platform interface mirrors those parts of the public interface that needs to
+perform platform-specific operations on some or all platforms.  The are also
+named the same except that the glfw function prefix is replaced by
+_glfwPlatform.
+
+Examples: `_glfwPlatformCreateWindow`
+
+The platform interface also defines structs that contain platform-specific
+global and per-object state.  Their names mirror those of the internal
+interface, except that an interface-specific suffix is added.
+
+Examples: `_GLFWwindowX11`, `_GLFWcontextWGL`
+
+These structs are incorporated as members into the internal interface structs
+using special macros that name them after the specific interface used.  This
+prevents shared code from accidentally using these members.
+
+Examples: `window->win32.handle`, `_glfw.x11.display`
+
+
+@section internals_event Event interface
+
+The event interface is implemented in the same shared source files as the public
+interface and is responsible for delivering the events it receives to the
+application, either via callbacks, via window state changes or both.
+
+The function names of the event interface use a `_glfwInput` prefix and the
+ObjectEvent pattern.
+
+Examples: `_glfwInputWindowFocus`, `_glfwInputCursorPos`
+
+
+@section internals_static Static functions
+
+Static functions may be used by any interface and have no prefixes or suffixes.
+These use headless camel case.
+
+Examples: `isValidElementForJoystick`
+
+
+@section internals_config Configuration macros
+
+GLFW uses a number of configuration macros to select at compile time which
+interfaces and code paths to use.  They are defined in the glfw_config.h header file,
+which is generated from the `glfw_config.h.in` file by CMake.
+
+Configuration macros the same style as tokens in the public interface, except
+with a leading underscore.
+
+Examples: `_GLFW_WIN32`, `_GLFW_BUILD_DLL`

+
+@page intro_guide Introduction to the API
+
+@tableofcontents
+
+This guide introduces the basic concepts of GLFW and describes initialization,
+error handling and API guarantees and limitations.  For a broad but shallow
+tutorial, see @ref quick_guide instead.  For details on a specific function in
+this category, see the @ref init.
+
+There are also guides for the other areas of GLFW.
+
+ - @ref window_guide
+ - @ref context_guide
+ - @ref vulkan_guide
+ - @ref monitor_guide
+ - @ref input_guide
+
+
+@section intro_init Initialization and termination
+
+Before most GLFW functions may be called, the library must be initialized.
+This initialization checks what features are available on the machine,
+enumerates monitors and joysticks, initializes the timer and performs any
+required platform-specific initialization.
+
+Only the following functions may be called before the library has been
+successfully initialized, and only from the main thread.
+
+ - @ref glfwGetVersion
+ - @ref glfwGetVersionString
+ - @ref glfwGetError
+ - @ref glfwSetErrorCallback
+ - @ref glfwInitHint
+ - @ref glfwInit
+ - @ref glfwTerminate
+
+Calling any other function before successful initialization will cause a @ref
+GLFW_NOT_INITIALIZED error.
+
+
+@subsection intro_init_init Initializing GLFW
+
+The library is initialized with @ref glfwInit, which returns `GLFW_FALSE` if an
+error occurred.
+
+@code
+if (!glfwInit())
+{
+    // Handle initialization failure
+}
+@endcode
+
+If any part of initialization fails, any parts that succeeded are terminated as
+if @ref glfwTerminate had been called.  The library only needs to be initialized
+once and additional calls to an already initialized library will return
+`GLFW_TRUE` immediately.
+
+Once the library has been successfully initialized, it should be terminated
+before the application exits.  Modern systems are very good at freeing resources
+allocated by programs that exit, but GLFW sometimes has to change global system
+settings and these might not be restored without termination.
+
+
+@subsection init_hints Initialization hints
+
+Initialization hints are set before @ref glfwInit and affect how the library
+behaves until termination.  Hints are set with @ref glfwInitHint.
+
+@code
+glfwInitHint(GLFW_JOYSTICK_HAT_BUTTONS, GLFW_FALSE);
+@endcode
+
+The values you set hints to are never reset by GLFW, but they only take effect
+during initialization.  Once GLFW has been initialized, any values you set will
+be ignored until the library is terminated and initialized again.
+
+Some hints are platform specific.  These may be set on any platform but they
+will only affect their specific platform.  Other platforms will ignore them.
+Setting these hints requires no platform specific headers or functions.
+
+
+@subsubsection init_hints_shared Shared init hints
+
+@anchor GLFW_JOYSTICK_HAT_BUTTONS
+__GLFW_JOYSTICK_HAT_BUTTONS__ specifies whether to also expose joystick hats as
+buttons, for compatibility with earlier versions of GLFW that did not have @ref
+glfwGetJoystickHats.  Set this with @ref glfwInitHint.
+
+
+@subsubsection init_hints_osx macOS specific init hints
+
+@anchor GLFW_COCOA_CHDIR_RESOURCES_hint
+__GLFW_COCOA_CHDIR_RESOURCES__ specifies whether to set the current directory to
+the application to the `Contents/Resources` subdirectory of the application's
+bundle, if present.  Set this with @ref glfwInitHint.
+
+@anchor GLFW_COCOA_MENUBAR_hint
+__GLFW_COCOA_MENUBAR__ specifies whether to create a basic menu bar, either from
+a nib or manually, when the first window is created, which is when AppKit is
+initialized.  Set this with @ref glfwInitHint.
+
+
+@subsubsection init_hints_values Supported and default values
+
+Initialization hint             | Default value | Supported values
+------------------------------- | ------------- | ----------------
+@ref GLFW_JOYSTICK_HAT_BUTTONS  | `GLFW_TRUE`   | `GLFW_TRUE` or `GLFW_FALSE`
+@ref GLFW_COCOA_CHDIR_RESOURCES | `GLFW_TRUE`   | `GLFW_TRUE` or `GLFW_FALSE`
+@ref GLFW_COCOA_MENUBAR         | `GLFW_TRUE`   | `GLFW_TRUE` or `GLFW_FALSE`
+
+
+@subsection intro_init_terminate Terminating GLFW
+
+Before your application exits, you should terminate the GLFW library if it has
+been initialized.  This is done with @ref glfwTerminate.
+
+@code
+glfwTerminate();
+@endcode
+
+This will destroy any remaining window, monitor and cursor objects, restore any
+modified gamma ramps, re-enable the screensaver if it had been disabled and free
+any other resources allocated by GLFW.
+
+Once the library is terminated, it is as if it had never been initialized and
+you will need to initialize it again before being able to use GLFW.  If the
+library was not initialized or had already been terminated, it return
+immediately.
+
+
+@section error_handling Error handling
+
+Some GLFW functions have return values that indicate an error, but this is often
+not very helpful when trying to figure out what happened or why it occurred.
+Other functions have no return value reserved for errors, so error notification
+needs a separate channel.  Finally, far from all GLFW functions have return
+values.
+
+The last [error code](@ref errors) for the calling thread can be queried at any
+time with @ref glfwGetError.
+
+@code
+int code = glfwGetError(NULL);
+
+if (code != GLFW_NO_ERROR)
+    handle_error(code);
+@endcode
+
+If no error has occurred since the last call, @ref GLFW_NO_ERROR (zero) is
+returned.  The error is cleared before the function returns.
+
+The error code indicates the general category of the error.  Some error codes,
+such as @ref GLFW_NOT_INITIALIZED has only a single meaning, whereas others like
+@ref GLFW_PLATFORM_ERROR are used for many different errors.
+
+GLFW often has more information about an error than its general category.  You
+can retrieve a UTF-8 encoded human-readable description along with the error
+code.  If no error has occurred since the last call, the description is set to
+`NULL`.
+
+@code
+const char* description;
+int code = glfwGetError(&description);
+
+if (description)
+    display_error_message(code, description);
+@endcode
+
+The retrieved description string is only valid until the next error occurs.
+This means you must make a copy of it if you want to keep it.
+
+You can also set an error callback, which will be called each time an error
+occurs.  It is set with @ref glfwSetErrorCallback.
+
+@code
+glfwSetErrorCallback(error_callback);
+@endcode
+
+The error callback receives the same error code and human-readable description
+returned by @ref glfwGetError.
+
+@code
+void error_callback(int code, const char* description)
+{
+    display_error_message(code, description);
+}
+@endcode
+
+The error callback is called after the error is stored, so calling @ref
+glfwGetError from within the error callback returns the same values as the
+callback argument.
+
+The description string passed to the callback is only valid until the error
+callback returns.  This means you must make a copy of it if you want to keep it.
+
+__Reported errors are never fatal.__  As long as GLFW was successfully
+initialized, it will remain initialized and in a safe state until terminated
+regardless of how many errors occur.  If an error occurs during initialization
+that causes @ref glfwInit to fail, any part of the library that was initialized
+will be safely terminated.
+
+Do not rely on a currently invalid call to generate a specific error, as in the
+future that same call may generate a different error or become valid.
+
+
+@section coordinate_systems Coordinate systems
+
+GLFW has two primary coordinate systems: the _virtual screen_ and the window
+_content area_ or _content area_.  Both use the same unit: _virtual screen
+coordinates_, or just _screen coordinates_, which don't necessarily correspond
+to pixels.
+
+<img src="spaces.svg" width="90%" />
+
+Both the virtual screen and the content area coordinate systems have the X-axis
+pointing to the right and the Y-axis pointing down.
+
+Window and monitor positions are specified as the position of the upper-left
+corners of their content areas relative to the virtual screen, while cursor
+positions are specified relative to a window's content area.
+
+Because the origin of the window's content area coordinate system is also the
+point from which the window position is specified, you can translate content
+area coordinates to the virtual screen by adding the window position.  The
+window frame, when present, extends out from the content area but does not
+affect the window position.
+
+Almost all positions and sizes in GLFW are measured in screen coordinates
+relative to one of the two origins above.  This includes cursor positions,
+window positions and sizes, window frame sizes, monitor positions and video mode
+resolutions.
+
+Two exceptions are the [monitor physical size](@ref monitor_size), which is
+measured in millimetres, and [framebuffer size](@ref window_fbsize), which is
+measured in pixels.
+
+Pixels and screen coordinates may map 1:1 on your machine, but they won't on
+every other machine, for example on a Mac with a Retina display.  The ratio
+between screen coordinates and pixels may also change at run-time depending on
+which monitor the window is currently considered to be on.
+
+
+@section guarantees_limitations Guarantees and limitations
+
+This section describes the conditions under which GLFW can be expected to
+function, barring bugs in the operating system or drivers.  Use of GLFW outside
+of these limits may work on some platforms, or on some machines, or some of the
+time, or on some versions of GLFW, but it may break at any time and this will
+not be considered a bug.
+
+
+@subsection lifetime Pointer lifetimes
+
+GLFW will never free any pointer you provide to it and you must never free any
+pointer it provides to you.
+
+Many GLFW functions return pointers to dynamically allocated structures, strings
+or arrays, and some callbacks are provided with strings or arrays.  These are
+always managed by GLFW and should never be freed by the application.  The
+lifetime of these pointers is documented for each GLFW function and callback.
+If you need to keep this data, you must copy it before its lifetime expires.
+
+Many GLFW functions accept pointers to structures or strings allocated by the
+application.  These are never freed by GLFW and are always the responsibility of
+the application.  If GLFW needs to keep the data in these structures or strings,
+it is copied before the function returns.
+
+Pointer lifetimes are guaranteed not to be shortened in future minor or patch
+releases.
+
+
+@subsection reentrancy Reentrancy
+
+GLFW event processing and object destruction are not reentrant.  This means that
+the following functions must not be called from any callback function:
+
+ - @ref glfwDestroyWindow
+ - @ref glfwDestroyCursor
+ - @ref glfwPollEvents
+ - @ref glfwWaitEvents
+ - @ref glfwWaitEventsTimeout
+ - @ref glfwTerminate
+
+These functions may be made reentrant in future minor or patch releases, but
+functions not on this list will not be made non-reentrant.
+
+
+@subsection thread_safety Thread safety
+
+Most GLFW functions must only be called from the main thread (the thread that
+calls main), but some may be called from any thread once the library has been
+initialized.  Before initialization the whole library is thread-unsafe.
+
+The reference documentation for every GLFW function states whether it is limited
+to the main thread.
+
+Initialization, termination, event processing and the creation and
+destruction of windows, cursors and OpenGL and OpenGL ES contexts are all
+restricted to the main thread due to limitations of one or several platforms.
+
+Because event processing must be performed on the main thread, all callbacks
+except for the error callback will only be called on that thread.  The error
+callback may be called on any thread, as any GLFW function may generate errors.
+
+The error code and description may be queried from any thread.
+
+ - @ref glfwGetError
+
+Empty events may be posted from any thread.
+
+ - @ref glfwPostEmptyEvent
+
+The window user pointer and close flag may be read and written from any thread,
+but this is not synchronized by GLFW.
+
+ - @ref glfwGetWindowUserPointer
+ - @ref glfwSetWindowUserPointer
+ - @ref glfwWindowShouldClose
+ - @ref glfwSetWindowShouldClose
+
+These functions for working with OpenGL and OpenGL ES contexts may be called
+from any thread, but the window object is not synchronized by GLFW.
+
+ - @ref glfwMakeContextCurrent
+ - @ref glfwGetCurrentContext
+ - @ref glfwSwapBuffers
+ - @ref glfwSwapInterval
+ - @ref glfwExtensionSupported
+ - @ref glfwGetProcAddress
+
+The raw timer functions may be called from any thread.
+
+ - @ref glfwGetTimerFrequency
+ - @ref glfwGetTimerValue
+
+The regular timer may be used from any thread, but reading and writing the timer
+offset is not synchronized by GLFW.
+
+ - @ref glfwGetTime
+ - @ref glfwSetTime
+
+Library version information may be queried from any thread.
+
+ - @ref glfwGetVersion
+ - @ref glfwGetVersionString
+
+All Vulkan related functions may be called from any thread.
+
+ - @ref glfwVulkanSupported
+ - @ref glfwGetRequiredInstanceExtensions
+ - @ref glfwGetInstanceProcAddress
+ - @ref glfwGetPhysicalDevicePresentationSupport
+ - @ref glfwCreateWindowSurface
+
+GLFW uses synchronization objects internally only to manage the per-thread
+context and error states.  Additional synchronization is left to the
+application.
+
+Functions that may currently be called from any thread will always remain so,
+but functions that are currently limited to the main thread may be updated to
+allow calls from any thread in future releases.
+
+
+@subsection compatibility Version compatibility
+
+GLFW uses [Semantic Versioning](https://semver.org/).  This guarantees source
+and binary backward compatibility with earlier minor versions of the API.  This
+means that you can drop in a newer version of the library and existing programs
+will continue to compile and existing binaries will continue to run.
+
+Once a function or constant has been added, the signature of that function or
+value of that constant will remain unchanged until the next major version of
+GLFW.  No compatibility of any kind is guaranteed between major versions.
+
+Undocumented behavior, i.e. behavior that is not described in the documentation,
+may change at any time until it is documented.
+
+If the reference documentation and the implementation differ, the reference
+documentation will almost always take precedence and the implementation will be
+fixed in the next release.  The reference documentation will also take
+precedence over anything stated in a guide.
+
+
+@subsection event_order Event order
+
+The order of arrival of related events is not guaranteed to be consistent
+across platforms.  The exception is synthetic key and mouse button release
+events, which are always delivered after the window defocus event.
+
+
+@section intro_version Version management
+
+GLFW provides mechanisms for identifying what version of GLFW your application
+was compiled against as well as what version it is currently running against.
+If you are loading GLFW dynamically (not just linking dynamically), you can use
+this to verify that the library binary is compatible with your application.
+
+
+@subsection intro_version_compile Compile-time version
+
+The compile-time version of GLFW is provided by the GLFW header with the
+`GLFW_VERSION_MAJOR`, `GLFW_VERSION_MINOR` and `GLFW_VERSION_REVISION` macros.
+
+@code
+printf("Compiled against GLFW %i.%i.%i\n",
+       GLFW_VERSION_MAJOR,
+       GLFW_VERSION_MINOR,
+       GLFW_VERSION_REVISION);
+@endcode
+
+
+@subsection intro_version_runtime Run-time version
+
+The run-time version can be retrieved with @ref glfwGetVersion, a function that
+may be called regardless of whether GLFW is initialized.
+
+@code
+int major, minor, revision;
+glfwGetVersion(&major, &minor, &revision);
+
+printf("Running against GLFW %i.%i.%i\n", major, minor, revision);
+@endcode
+
+
+@subsection intro_version_string Version string
+
+GLFW 3 also provides a compile-time generated version string that describes the
+version, platform, compiler and any platform-specific compile-time options.
+This is primarily intended for submitting bug reports, to allow developers to
+see which code paths are enabled in a binary.
+
+The version string is returned by @ref glfwGetVersionString, a function that may
+be called regardless of whether GLFW is initialized.
+
+__Do not use the version string__ to parse the GLFW library version.  The @ref
+glfwGetVersion function already provides the version of the running library
+binary.
+
+The format of the string is as follows:
+ - The version of GLFW
+ - The name of the window system API
+ - The name of the context creation API
+ - Any additional options or APIs
+
+For example, when compiling GLFW 3.0 with MinGW using the Win32 and WGL
+back ends, the version string may look something like this:
+
+@code
+3.0.0 Win32 WGL MinGW
+@endcode

+@page monitor_guide Monitor guide
+
+@tableofcontents
+
+This guide introduces the monitor related functions of GLFW.  For details on
+a specific function in this category, see the @ref monitor.  There are also
+guides for the other areas of GLFW.
+
+ - @ref intro_guide
+ - @ref window_guide

+
+@section monitor_object Monitor objects
+
+A monitor object represents a currently connected monitor and is represented as
+a pointer to the [opaque](https://en.wikipedia.org/wiki/Opaque_data_type) type
+@ref GLFWmonitor.  Monitor objects cannot be created or destroyed by the
+application and retain their addresses until the monitors they represent are
+disconnected or until the library is [terminated](@ref intro_init_terminate).
+
+Each monitor has a current video mode, a list of supported video modes,
+a virtual position, a human-readable name, an estimated physical size and
+a gamma ramp.  One of the monitors is the primary monitor.
+
+The virtual position of a monitor is in
+[screen coordinates](@ref coordinate_systems) and, together with the current
+video mode, describes the viewports that the connected monitors provide into the
+virtual desktop that spans them.
+
+To see how GLFW views your monitor setup and its available video modes, run the
+`monitors` test program.
+
+
+@subsection monitor_monitors Retrieving monitors
+
+The primary monitor is returned by @ref glfwGetPrimaryMonitor.  It is the user's
+preferred monitor and is usually the one with global UI elements like task bar
+or menu bar.
+
+@code
+GLFWmonitor* primary = glfwGetPrimaryMonitor();
+@endcode
+
+You can retrieve all currently connected monitors with @ref glfwGetMonitors.
+See the reference documentation for the lifetime of the returned array.
+
+@code
+int count;
+GLFWmonitor** monitors = glfwGetMonitors(&count);
+@endcode
+
+The primary monitor is always the first monitor in the returned array, but other
+monitors may be moved to a different index when a monitor is connected or
+disconnected.
+
+
+@subsection monitor_event Monitor configuration changes
+
+If you wish to be notified when a monitor is connected or disconnected, set
+a monitor callback.
+
+@code
+glfwSetMonitorCallback(monitor_callback);
+@endcode
+
+The callback function receives the handle for the monitor that has been
+connected or disconnected and the event that occurred.
+
+@code
+void monitor_callback(GLFWmonitor* monitor, int event)
+{
+    if (event == GLFW_CONNECTED)
+    {
+        // The monitor was connected
+    }
+    else if (event == GLFW_DISCONNECTED)
+    {
+        // The monitor was disconnected
+    }
+}
+@endcode
+
+If a monitor is disconnected, all windows that are full screen on it will be
+switched to windowed mode before the callback is called.  Only @ref
+glfwGetMonitorName and @ref glfwGetMonitorUserPointer will return useful values
+for a disconnected monitor and only before the monitor callback returns.
+
+
+@section monitor_properties Monitor properties
+
+Each monitor has a current video mode, a list of supported video modes,
+a virtual position, a content scale, a human-readable name, a user pointer, an
+estimated physical size and a gamma ramp.
+
+
+@subsection monitor_modes Video modes
+
+GLFW generally does a good job selecting a suitable video mode when you create
+a full screen window, change its video mode or make a windowed one full
+screen, but it is sometimes useful to know exactly which video modes are
+supported.
+
+Video modes are represented as @ref GLFWvidmode structures.  You can get an
+array of the video modes supported by a monitor with @ref glfwGetVideoModes.
+See the reference documentation for the lifetime of the returned array.
+
+@code
+int count;
+GLFWvidmode* modes = glfwGetVideoModes(monitor, &count);
+@endcode
+
+To get the current video mode of a monitor call @ref glfwGetVideoMode.  See the
+reference documentation for the lifetime of the returned pointer.
+
+@code
+const GLFWvidmode* mode = glfwGetVideoMode(monitor);
+@endcode
+
+The resolution of a video mode is specified in
+[screen coordinates](@ref coordinate_systems), not pixels.
+
+
+@subsection monitor_size Physical size
+
+The physical size of a monitor in millimetres, or an estimation of it, can be
+retrieved with @ref glfwGetMonitorPhysicalSize.  This has no relation to its
+current _resolution_, i.e. the width and height of its current
+[video mode](@ref monitor_modes).
+
+@code
+int width_mm, height_mm;
+glfwGetMonitorPhysicalSize(monitor, &width_mm, &height_mm);
+@endcode
+
+While this can be used to calculate the raw DPI of a monitor, this is often not
+useful.  Instead use the [monitor content scale](@ref monitor_scale) and
+[window content scale](@ref window_scale) to scale your content.
+
+
+@subsection monitor_scale Content scale
+
+The content scale for a monitor can be retrieved with @ref
+glfwGetMonitorContentScale.
+
+@code
+float xscale, yscale;
+glfwGetMonitorContentScale(monitor, &xscale, &yscale);
+@endcode
+
+The content scale is the ratio between the current DPI and the platform's
+default DPI.  This is especially important for text and any UI elements.  If the
+pixel dimensions of your UI scaled by this look appropriate on your machine then
+it should appear at a reasonable size on other machines regardless of their DPI
+and scaling settings.  This relies on the system DPI and scaling settings being
+somewhat correct.
+
+The content scale may depend on both the monitor resolution and pixel density
+and on user settings.  It may be very different from the raw DPI calculated from
+the physical size and current resolution.
+
+
+@subsection monitor_pos Virtual position
+
+The position of the monitor on the virtual desktop, in
+[screen coordinates](@ref coordinate_systems), can be retrieved with @ref
+glfwGetMonitorPos.
+
+@code
+int xpos, ypos;
+glfwGetMonitorPos(monitor, &xpos, &ypos);
+@endcode
+
+
+@subsection monitor_workarea Work area
+
+The area of a monitor not occupied by global task bars or menu bars is the work
+area.  This is specified in [screen coordinates](@ref coordinate_systems) and
+can be retrieved with @ref glfwGetMonitorWorkarea.
+
+@code
+int xpos, ypos, width, height;
+glfwGetMonitorWorkarea(monitor, &xpos, &ypos, &width, &height);
+@endcode
+
+
+@subsection monitor_name Human-readable name
+
+The human-readable, UTF-8 encoded name of a monitor is returned by @ref
+glfwGetMonitorName.  See the reference documentation for the lifetime of the
+returned string.
+
+@code
+const char* name = glfwGetMonitorName(monitor);
+@endcode
+
+Monitor names are not guaranteed to be unique.  Two monitors of the same model
+and make may have the same name.  Only the monitor handle is guaranteed to be
+unique, and only until that monitor is disconnected.
+
+
+@subsection monitor_userptr User pointer
+
+Each monitor has a user pointer that can be set with @ref
+glfwSetMonitorUserPointer and queried with @ref glfwGetMonitorUserPointer.  This
+can be used for any purpose you need and will not be modified by GLFW.  The
+value will be kept until the monitor is disconnected or until the library is
+terminated.
+
+The initial value of the pointer is `NULL`.
+
+
+@subsection monitor_gamma Gamma ramp
+
+The gamma ramp of a monitor can be set with @ref glfwSetGammaRamp, which accepts
+a monitor handle and a pointer to a @ref GLFWgammaramp structure.
+
+@code
+GLFWgammaramp ramp;
+unsigned short red[256], green[256], blue[256];
+
+ramp.size = 256;
+ramp.red = red;
+ramp.green = green;
+ramp.blue = blue;
+
+for (i = 0;  i < ramp.size;  i++)
+{
+    // Fill out gamma ramp arrays as desired
+}
+
+glfwSetGammaRamp(monitor, &ramp);
+@endcode
+
+The gamma ramp data is copied before the function returns, so there is no need
+to keep it around once the ramp has been set.
+
+It is recommended that your gamma ramp have the same size as the current gamma
+ramp for that monitor.
+
+The current gamma ramp for a monitor is returned by @ref glfwGetGammaRamp.  See
+the reference documentation for the lifetime of the returned structure.
+
+@code
+const GLFWgammaramp* ramp = glfwGetGammaRamp(monitor);
+@endcode
+
+If you wish to set a regular gamma ramp, you can have GLFW calculate it for you
+from the desired exponent with @ref glfwSetGamma, which in turn calls @ref
+glfwSetGammaRamp with the resulting ramp.
+
+@code
+glfwSetGamma(monitor, 1.0);
+@endcode
+
+To experiment with gamma correction via the @ref glfwSetGamma function, run the
+`gamma` test program.
+
+@note The software controlled gamma ramp is applied _in addition_ to the
+hardware gamma correction, which today is usually an approximation of sRGB
+gamma.  This means that setting a perfectly linear ramp, or gamma 1.0, will
+produce the default (usually sRGB-like) behavior.

+
+@page moving_guide Moving from GLFW 2 to 3
+
+@tableofcontents
+
+This is a transition guide for moving from GLFW 2 to 3.  It describes what has
+changed or been removed, but does _not_ include
+[new features](@ref news) unless they are required when moving an existing code
+base onto the new API.  For example, the new multi-monitor functions are
+required to create full screen windows with GLFW 3.
+
+
+@section moving_removed Changed and removed features
+
+@subsection moving_renamed_files Renamed library and header file
+
+The GLFW 3 header is named @ref glfw3.h and moved to the `GLFW` directory, to
+avoid collisions with the headers of other major versions.  Similarly, the GLFW
+3 library is named `glfw3,` except when it's installed as a shared library on
+Unix-like systems, where it uses the
+[soname](https://en.wikipedia.org/wiki/soname) `libglfw.so.3`.
+
+@par Old syntax
+@code
+#include <GL/glfw.h>
+@endcode
+
+@par New syntax
+@code
+#include <GLFW/glfw3.h>
+@endcode
+
+
+@subsection moving_threads Removal of threading functions
+
+The threading functions have been removed, including the per-thread sleep
+function.  They were fairly primitive, under-used, poorly integrated and took
+time away from the focus of GLFW (i.e.  context, input and window).  There are
+better threading libraries available and native threading support is available
+in both [C++11](https://en.cppreference.com/w/cpp/thread) and
+[C11](https://en.cppreference.com/w/c/thread), both of which are gaining
+traction.
+
+If you wish to use the C++11 or C11 facilities but your compiler doesn't yet
+support them, see the
+[TinyThread++](https://gitorious.org/tinythread/tinythreadpp) and
+[TinyCThread](https://github.com/tinycthread/tinycthread) projects created by
+the original author of GLFW.  These libraries implement a usable subset of the
+threading APIs in C++11 and C11, and in fact some GLFW 3 test programs use
+TinyCThread.
+
+However, GLFW 3 has better support for _use from multiple threads_ than GLFW
+2 had.  Contexts can be made current on any thread, although only a single
+thread at a time, and the documentation explicitly states which functions may be
+used from any thread and which must only be used from the main thread.
+
+@par Removed functions
+`glfwSleep`, `glfwCreateThread`, `glfwDestroyThread`, `glfwWaitThread`,
+`glfwGetThreadID`, `glfwCreateMutex`, `glfwDestroyMutex`, `glfwLockMutex`,
+`glfwUnlockMutex`, `glfwCreateCond`, `glfwDestroyCond`, `glfwWaitCond`,
+`glfwSignalCond`, `glfwBroadcastCond` and `glfwGetNumberOfProcessors`.
+
+@par Removed types
+`GLFWthreadfun`
+
+
+@subsection moving_image Removal of image and texture loading
+
+The image and texture loading functions have been removed.  They only supported
+the Targa image format, making them mostly useful for beginner level examples.
+To become of sufficiently high quality to warrant keeping them in GLFW 3, they
+would need not only to support other formats, but also modern extensions to
+OpenGL texturing.  This would either add a number of external
+dependencies (libjpeg, libpng, etc.), or force GLFW to ship with inline versions
+of these libraries.
+
+As there already are libraries doing this, it is unnecessary both to duplicate
+the work and to tie the duplicate to GLFW.  The resulting library would also be
+platform-independent, as both OpenGL and stdio are available wherever GLFW is.
+
+@par Removed functions
+`glfwReadImage`, `glfwReadMemoryImage`, `glfwFreeImage`, `glfwLoadTexture2D`,
+`glfwLoadMemoryTexture2D` and `glfwLoadTextureImage2D`.
+
+
+@subsection moving_stdcall Removal of GLFWCALL macro
+
+The `GLFWCALL` macro, which made callback functions use
+[__stdcall](https://msdn.microsoft.com/en-us/library/zxk0tw93.aspx) on Windows,
+has been removed.  GLFW is written in C, not Pascal.  Removing this macro means
+there's one less thing for application programmers to remember, i.e. the
+requirement to mark all callback functions with `GLFWCALL`.  It also simplifies
+the creation of DLLs and DLL link libraries, as there's no need to explicitly
+disable `@n` entry point suffixes.
+
+@par Old syntax
+@code
+void GLFWCALL callback_function(...);
+@endcode
+
+@par New syntax
+@code
+void callback_function(...);
+@endcode
+
+
+@subsection moving_window_handles Window handle parameters
+
+Because GLFW 3 supports multiple windows, window handle parameters have been
+added to all window-related GLFW functions and callbacks.  The handle of
+a newly created window is returned by @ref glfwCreateWindow (formerly
+`glfwOpenWindow`).  Window handles are pointers to the
+[opaque](https://en.wikipedia.org/wiki/Opaque_data_type) type @ref GLFWwindow.
+
+@par Old syntax
+@code
+glfwSetWindowTitle("New Window Title");
+@endcode
+
+@par New syntax
+@code
+glfwSetWindowTitle(window, "New Window Title");
+@endcode
+
+
+@subsection moving_monitor Explicit monitor selection
+
+GLFW 3 provides support for multiple monitors.  To request a full screen mode window,
+instead of passing `GLFW_FULLSCREEN` you specify which monitor you wish the
+window to use.  The @ref glfwGetPrimaryMonitor function returns the monitor that
+GLFW 2 would have selected, but there are many other
+[monitor functions](@ref monitor_guide).  Monitor handles are pointers to the
+[opaque](https://en.wikipedia.org/wiki/Opaque_data_type) type @ref GLFWmonitor.
+
+@par Old basic full screen
+@code
+glfwOpenWindow(640, 480, 8, 8, 8, 0, 24, 0, GLFW_FULLSCREEN);
+@endcode
+
+@par New basic full screen
+@code
+window = glfwCreateWindow(640, 480, "My Window", glfwGetPrimaryMonitor(), NULL);
+@endcode
+
+@note The framebuffer bit depth parameters of `glfwOpenWindow` have been turned
+into [window hints](@ref window_hints), but as they have been given
+[sane defaults](@ref window_hints_values) you rarely need to set these hints.
+
+
+@subsection moving_autopoll Removal of automatic event polling
+
+GLFW 3 does not automatically poll for events in @ref glfwSwapBuffers, meaning
+you need to call @ref glfwPollEvents or @ref glfwWaitEvents yourself.  Unlike
+buffer swap, which acts on a single window, the event processing functions act
+on all windows at once.
+
+@par Old basic main loop
+@code
+while (...)
+{
+    // Process input
+    // Render output
+    glfwSwapBuffers();
+}
+@endcode
+
+@par New basic main loop
+@code
+while (...)
+{
+    // Process input
+    // Render output
+    glfwSwapBuffers(window);
+    glfwPollEvents();
+}
+@endcode
+
+
+@subsection moving_context Explicit context management
+
+Each GLFW 3 window has its own OpenGL context and only you, the application
+programmer, can know which context should be current on which thread at any
+given time.  Therefore, GLFW 3 leaves that decision to you.
+
+This means that you need to call @ref glfwMakeContextCurrent after creating
+a window before you can call any OpenGL functions.
+
+
+@subsection moving_hidpi Separation of window and framebuffer sizes
+
+Window positions and sizes now use screen coordinates, which may not be the same
+as pixels on machines with high-DPI monitors.  This is important as OpenGL uses
+pixels, not screen coordinates.  For example, the rectangle specified with
+`glViewport` needs to use pixels.  Therefore, framebuffer size functions have
+been added.  You can retrieve the size of the framebuffer of a window with @ref
+glfwGetFramebufferSize function.  A framebuffer size callback has also been
+added, which can be set with @ref glfwSetFramebufferSizeCallback.
+
+@par Old basic viewport setup
+@code
+glfwGetWindowSize(&width, &height);
+glViewport(0, 0, width, height);
+@endcode
+
+@par New basic viewport setup
+@code
+glfwGetFramebufferSize(window, &width, &height);
+glViewport(0, 0, width, height);
+@endcode
+
+
+@subsection moving_window_close Window closing changes
+
+The `GLFW_OPENED` window parameter has been removed.  As long as the window has
+not been destroyed, whether through @ref glfwDestroyWindow or @ref
+glfwTerminate, the window is "open".
+
+A user attempting to close a window is now just an event like any other.  Unlike
+GLFW 2, windows and contexts created with GLFW 3 will never be destroyed unless
+you choose them to be.  Each window now has a close flag that is set to
+`GLFW_TRUE` when the user attempts to close that window.  By default, nothing else
+happens and the window stays visible.  It is then up to you to either destroy
+the window, take some other action or ignore the request.
+
+You can query the close flag at any time with @ref glfwWindowShouldClose and set
+it at any time with @ref glfwSetWindowShouldClose.
+
+@par Old basic main loop
+@code
+while (glfwGetWindowParam(GLFW_OPENED))
+{
+    ...
+}
+@endcode
+
+@par New basic main loop
+@code
+while (!glfwWindowShouldClose(window))
+{
+    ...
+}
+@endcode
+
+The close callback no longer returns a value.  Instead, it is called after the
+close flag has been set so it can override its value, if it chooses to, before
+event processing completes.  You may however not call @ref glfwDestroyWindow
+from the close callback (or any other window related callback).
+
+@par Old syntax
+@code
+int GLFWCALL window_close_callback(void);
+@endcode
+
+@par New syntax
+@code
+void window_close_callback(GLFWwindow* window);
+@endcode
+
+@note GLFW never clears the close flag to `GLFW_FALSE`, meaning you can use it
+for other reasons to close the window as well, for example the user choosing
+Quit from an in-game menu.
+
+
+@subsection moving_hints Persistent window hints
+
+The `glfwOpenWindowHint` function has been renamed to @ref glfwWindowHint.
+
+Window hints are no longer reset to their default values on window creation, but
+instead retain their values until modified by @ref glfwWindowHint or @ref
+glfwDefaultWindowHints, or until the library is terminated and re-initialized.
+
+
+@subsection moving_video_modes Video mode enumeration
+
+Video mode enumeration is now per-monitor.  The @ref glfwGetVideoModes function
+now returns all available modes for a specific monitor instead of requiring you
+to guess how large an array you need.  The `glfwGetDesktopMode` function, which
+had poorly defined behavior, has been replaced by @ref glfwGetVideoMode, which
+returns the current mode of a monitor.
+
+
+@subsection moving_char_up Removal of character actions
+
+The action parameter of the [character callback](@ref GLFWcharfun) has been
+removed.  This was an artefact of the origin of GLFW, i.e. being developed in
+English by a Swede.  However, many keyboard layouts require more than one key to
+produce characters with diacritical marks. Even the Swedish keyboard layout
+requires this for uncommon cases like ü.
+
+@par Old syntax
+@code
+void GLFWCALL character_callback(int character, int action);
+@endcode
+
+@par New syntax
+@code
+void character_callback(GLFWwindow* window, int character);
+@endcode
+
+
+@subsection moving_cursorpos Cursor position changes
+
+The `glfwGetMousePos` function has been renamed to @ref glfwGetCursorPos,
+`glfwSetMousePos` to @ref glfwSetCursorPos and `glfwSetMousePosCallback` to @ref
+glfwSetCursorPosCallback.
+
+The cursor position is now `double` instead of `int`, both for the direct
+functions and for the callback.  Some platforms can provide sub-pixel cursor
+movement and this data is now passed on to the application where available.  On
+platforms where this is not provided, the decimal part is zero.
+
+GLFW 3 only allows you to position the cursor within a window using @ref
+glfwSetCursorPos (formerly `glfwSetMousePos`) when that window is active.
+Unless the window is active, the function fails silently.
+
+
+@subsection moving_wheel Wheel position replaced by scroll offsets
+
+The `glfwGetMouseWheel` function has been removed.  Scrolling is the input of
+offsets and has no absolute position.  The mouse wheel callback has been
+replaced by a [scroll callback](@ref GLFWscrollfun) that receives
+two-dimensional floating point scroll offsets.  This allows you to receive
+precise scroll data from for example modern touchpads.
+
+@par Old syntax
+@code
+void GLFWCALL mouse_wheel_callback(int position);
+@endcode
+
+@par New syntax
+@code
+void scroll_callback(GLFWwindow* window, double xoffset, double yoffset);
+@endcode
+
+@par Removed functions
+`glfwGetMouseWheel`
+
+
+@subsection moving_repeat Key repeat action
+
+The `GLFW_KEY_REPEAT` enable has been removed and key repeat is always enabled
+for both keys and characters.  A new key action, `GLFW_REPEAT`, has been added
+to allow the [key callback](@ref GLFWkeyfun) to distinguish an initial key press
+from a repeat.  Note that @ref glfwGetKey still returns only `GLFW_PRESS` or
+`GLFW_RELEASE`.
+
+
+@subsection moving_keys Physical key input
+
+GLFW 3 key tokens map to physical keys, unlike in GLFW 2 where they mapped to
+the values generated by the current keyboard layout.  The tokens are named
+according to the values they would have using the standard US layout, but this
+is only a convenience, as most programmers are assumed to know that layout.
+This means that (for example) `GLFW_KEY_LEFT_BRACKET` is always a single key and
+is the same key in the same place regardless of what keyboard layouts the users
+of your program has.
+
+The key input facility was never meant for text input, although using it that
+way worked slightly better in GLFW 2.  If you were using it to input text, you
+should be using the character callback instead, on both GLFW 2 and 3.  This will
+give you the characters being input, as opposed to the keys being pressed.
+
+GLFW 3 has key tokens for all keys on a standard 105 key keyboard, so instead of
+having to remember whether to check for `'a'` or `'A'`, you now check for
+`GLFW_KEY_A`.
+
+
+@subsection moving_joystick Joystick function changes
+
+The `glfwGetJoystickPos` function has been renamed to @ref glfwGetJoystickAxes.
+
+The `glfwGetJoystickParam` function and the `GLFW_PRESENT`, `GLFW_AXES` and
+`GLFW_BUTTONS` tokens have been replaced by the @ref glfwJoystickPresent
+function as well as axis and button counts returned by the @ref
+glfwGetJoystickAxes and @ref glfwGetJoystickButtons functions.
+
+
+@subsection moving_mbcs Win32 MBCS support
+
+The Win32 port of GLFW 3 will not compile in
+[MBCS mode](https://msdn.microsoft.com/en-us/library/5z097dxa.aspx).
+However, because the use of the Unicode version of the Win32 API doesn't affect
+the process as a whole, but only those windows created using it, it's perfectly
+possible to call MBCS functions from other parts of the same application.
+Therefore, even if an application using GLFW has MBCS mode code, there's no need
+for GLFW itself to support it.
+
+
+@subsection moving_windows Support for versions of Windows older than XP
+
+All explicit support for version of Windows older than XP has been removed.
+There is no code that actively prevents GLFW 3 from running on these earlier
+versions, but it uses Win32 functions that those versions lack.
+
+Windows XP was released in 2001, and by now (January 2015) it has not only
+replaced almost all earlier versions of Windows, but is itself rapidly being
+replaced by Windows 7 and 8.  The MSDN library doesn't even provide
+documentation for version older than Windows 2000, making it difficult to
+maintain compatibility with these versions even if it was deemed worth the
+effort.
+
+The Win32 API has also not stood still, and GLFW 3 uses many functions only
+present on Windows XP or later.  Even supporting an OS as new as XP (new
+from the perspective of GLFW 2, which still supports Windows 95) requires
+runtime checking for a number of functions that are present only on modern
+version of Windows.
+
+
+@subsection moving_syskeys Capture of system-wide hotkeys
+
+The ability to disable and capture system-wide hotkeys like Alt+Tab has been
+removed.  Modern applications, whether they're games, scientific visualisations
+or something else, are nowadays expected to be good desktop citizens and allow
+these hotkeys to function even when running in full screen mode.
+
+
+@subsection moving_terminate Automatic termination
+
+GLFW 3 does not register @ref glfwTerminate with `atexit` at initialization,
+because `exit` calls registered functions from the calling thread and while it
+is permitted to call `exit` from any thread, @ref glfwTerminate must only be
+called from the main thread.
+
+To release all resources allocated by GLFW, you should call @ref glfwTerminate
+yourself, from the main thread, before the program terminates.  Note that this
+destroys all windows not already destroyed with @ref glfwDestroyWindow,
+invalidating any window handles you may still have.
+
+
+@subsection moving_glu GLU header inclusion
+
+GLFW 3 does not by default include the GLU header and GLU itself has been
+deprecated by [Khronos](https://en.wikipedia.org/wiki/Khronos_Group).  __New
+projects should not use GLU__, but if you need it for legacy code that
+has been moved to GLFW 3, you can request that the GLFW header includes it by
+defining @ref GLFW_INCLUDE_GLU before the inclusion of the GLFW header.
+
+@par Old syntax
+@code
+#include <GL/glfw.h>
+@endcode
+
+@par New syntax
+@code
+#define GLFW_INCLUDE_GLU
+#include <GLFW/glfw3.h>
+@endcode
+
+There are many libraries that offer replacements for the functionality offered
+by GLU.  For the matrix helper functions, see math libraries like
+[GLM](https://github.com/g-truc/glm) (for C++),
+[linmath.h](https://github.com/datenwolf/linmath.h) (for C) and others.  For the
+tessellation functions, see for example
+[libtess2](https://github.com/memononen/libtess2).

+
+@section news_33 Release notes for version 3.3
+
+These are the release notes for version 3.3.  For a more detailed view including
+all fixed bugs see the [version history](https://www.glfw.org/changelog.html).
+
+Please review the caveats, deprecations and removals if your project was written
+against an earlier version of GLFW 3.
+
+
+@subsection features_33 New features in version 3.3
+
+@subsubsection gamepad_33 Gamepad input via SDL_GameControllerDB
+
+GLFW can now remap game controllers to a standard Xbox-like layout using
+a built-in copy of SDL_GameControllerDB.  Call @ref glfwJoystickIsGamepad to
+check if a joystick has a mapping, @ref glfwGetGamepadState to retrieve its
+input state, @ref glfwUpdateGamepadMappings to add newer mappings and @ref
+glfwGetGamepadName and @ref glfwGetJoystickGUID for mapping related information.
+
+For more information see @ref gamepad.
+
+
+@subsubsection moltenvk_33 Support for Vulkan on macOS via MoltenVK
+
+GLFW now supports [MoltenVK](https://moltengl.com/moltenvk/), a Vulkan
+implementation on top of the Metal API, and its `VK_MVK_macos_surface` window
+surface creation extension.  MoltenVK is included in the [macOS Vulkan
+SDK](https://vulkan.lunarg.com/).
+
+For more information see @ref vulkan_guide.
+
+
+@subsubsection content_scale_33 Content scale queries for DPI-aware rendering
+
+GLFW now provides content scales for windows and monitors, i.e. the ratio
+between their current DPI and the platform's default DPI, with @ref
+glfwGetWindowContentScale and @ref glfwGetMonitorContentScale.
+
+Changes of the content scale of a window can be received with the window content
+scale callback, set with @ref glfwSetWindowContentScaleCallback.
+
+The @ref GLFW_SCALE_TO_MONITOR window hint enables automatic resizing of a
+window by the content scale of the monitor it is placed, on platforms like
+Windows where this is necessary.  This takes effect both on creation and when
+the window is moved between monitors.  It is related to but different from
+[GLFW_COCOA_RETINA_FRAMEBUFFER](@ref GLFW_COCOA_RETINA_FRAMEBUFFER_hint).
+
+For more information see @ref window_scale.
+
+
+@subsubsection setwindowattrib_33 Support for updating window attributes
+
+GLFW now supports changing the [GLFW_DECORATED](@ref GLFW_DECORATED_attrib),
+[GLFW_RESIZABLE](@ref GLFW_RESIZABLE_attrib),
+[GLFW_FLOATING](@ref GLFW_FLOATING_attrib),
+[GLFW_AUTO_ICONIFY](@ref GLFW_AUTO_ICONIFY_attrib) and
+[GLFW_FOCUS_ON_SHOW](@ref GLFW_FOCUS_ON_SHOW_attrib) attributes for existing
+windows with @ref glfwSetWindowAttrib.
+
+For more information see @ref window_attribs.
+
+
+@subsubsection raw_motion_33 Support for raw mouse motion
+
+GLFW now supports raw (unscaled and unaccelerated) mouse motion in disabled
+cursor mode with the [GLFW_RAW_MOUSE_MOTION](@ref GLFW_RAW_MOUSE_MOTION) input
+mode.  Raw mouse motion input is not yet implemented on macOS.  Call @ref
+glfwRawMouseMotionSupported to check if GLFW can provide raw mouse motion on the
+current system.
+
+For more information see @ref raw_mouse_motion.
+
+
+@subsubsection joysticks_33 Joystick hats
+
+GLFW can now return the state of hats (i.e. POVs or D-pads) of a joystick with
+@ref glfwGetJoystickHats.  For compatibility, hats are also exposed as buttons.
+This can be disabled with the @ref GLFW_JOYSTICK_HAT_BUTTONS initialization
+hint.
+
+For more information see @ref joystick_hat.
+
+
+@subsubsection geterror_33 Error query
+
+GLFW now supports querying the last error code for the calling thread and its
+human-readable description with @ref glfwGetError.  This can be used instead of
+or together with the error callback.
+
+For more information see @ref error_handling.
+
+
+@subsubsection init_hints_33 Support for initialization hints
+
+GLFW now supports setting library initialization hints with @ref glfwInitHint.
+These must be set before initialization to take effect.  Some of these hints are
+platform specific but are safe to set on any platform.
+
+For more information see @ref init_hints.
+
+
+@subsubsection attention_33 User attention request
+
+GLFW now supports requesting user attention with @ref
+glfwRequestWindowAttention.  Where possible this calls attention to the
+specified window.  On platforms like macOS it calls attention to the whole
+application.
+
+For more information see @ref window_attention.
+
+
+@subsubsection maximize_33 Window maximization callback
+
+GLFW now supports notifying the application that the window has been maximized
+@ref glfwSetWindowMaximizeCallback.  This is called both when the window was
+maximized by the user and when it was done with @ref glfwMaximizeWindow.
+
+For more information see @ref window_maximize.
+
+
+@subsubsection workarea_33 Query for the monitor work area
+
+GLFW now supports querying the work area of a monitor, i.e. the area not
+occupied by task bars or global menu bars, with @ref glfwGetMonitorWorkarea.  On
+platforms that lack this concept, the whole area of the monitor is returned.
+
+For more information see @ref monitor_workarea.
+
+
+@subsubsection transparency_33 Transparent windows and framebuffers
+
+GLFW now supports the creation of windows with transparent framebuffers on
+systems with desktop compositing enabled with the @ref
+GLFW_TRANSPARENT_FRAMEBUFFER window hint and attribute.  This hint must be set
+before window creation and leaves any window decorations opaque.
+
+GLFW now also supports whole window transparency with @ref glfwGetWindowOpacity
+and @ref glfwSetWindowOpacity.  This value controls the opacity of the whole
+window including decorations and unlike framebuffer transparency can be changed
+at any time after window creation.
+
+For more information see @ref window_transparency.
+
+
+@subsubsection key_scancode_33 Query for the scancode of a key
+
+GLFW now supports querying the platform dependent scancode of any physical key
+with @ref glfwGetKeyScancode.
+
+For more information see @ref input_key.
+
+
+@subsubsection center_cursor_33 Cursor centering window hint
+
+GLFW now supports controlling whether the cursor is centered over newly created
+full screen windows with the [GLFW_CENTER_CURSOR](@ref GLFW_CENTER_CURSOR_hint)
+window hint.  It is enabled by default.
+
+
+@subsubsection cursor_hover_33 Mouse cursor hover window attribute
+
+GLFW now supports polling whether the cursor is hovering over the window content
+area with the [GLFW_HOVERED](@ref GLFW_HOVERED_attrib) window attribute.  This
+attribute corresponds to the [cursor enter/leave](@ref cursor_enter) event.
+
+
+@subsubsection focusonshow_33 Window hint and attribute for input focus on show
+
+GLFW now has the [GLFW_FOCUS_ON_SHOW](@ref GLFW_DECORATED_hint) window hint and
+attribute for controlling whether a window gets input focus when shown.  It is
+enabled by default.  It applies both when creating an visible window with @ref
+glfwCreateWindow and when showing it with @ref glfwShowWindow.
+
+This is a workaround for GLFW 3.0 lacking @ref glfwFocusWindow and will be
+corrected in the next major version.
+
+For more information see @ref window_hide.
+
+
+@subsubsection device_userptr_33 Monitor and joystick user pointers
+
+GLFW now supports setting and querying user pointers for connected monitors and
+joysticks with @ref glfwSetMonitorUserPointer, @ref glfwGetMonitorUserPointer,
+@ref glfwSetJoystickUserPointer and @ref glfwGetJoystickUserPointer.
+
+For more information see @ref monitor_userptr and @ref joystick_userptr.
+
+
+@subsubsection macos_nib_33 macOS menu bar from nib file
+
+GLFW will now load a `MainMenu.nib` file if found in the `Contents/Resources`
+directory of the application bundle, as a way to replace the GLFW menu bar
+without recompiling GLFW.  This behavior can be disabled with the
+[GLFW_COCOA_MENUBAR](@ref GLFW_COCOA_MENUBAR_hint) initialization hint.
+
+
+@subsubsection glext_33 Support for more context creation extensions
+
+The context hint @ref GLFW_SRGB_CAPABLE now supports OpenGL ES via
+`WGL_EXT_colorspace`, the context hint @ref GLFW_CONTEXT_NO_ERROR now supports
+`WGL_ARB_create_context_no_error` and `GLX_ARB_create_context_no_error`, the
+context hint @ref GLFW_CONTEXT_RELEASE_BEHAVIOR now supports
+`EGL_KHR_context_flush_control` and @ref glfwGetProcAddress now supports
+`EGL_KHR_get_all_proc_addresses`.
+
+
+@subsubsection osmesa_33 OSMesa off-screen context creation support
+
+GLFW now supports creating off-screen OpenGL contexts using
+[OSMesa](https://www.mesa3d.org/osmesa.html) by setting
+[GLFW_CONTEXT_CREATION_API](@ref GLFW_CONTEXT_CREATION_API_hint) to
+`GLFW_OSMESA_CONTEXT_API`.  Native access function have been added to retrieve
+the OSMesa color and depth buffers.
+
+There is also a new null backend that uses OSMesa as its native context
+creation API, intended for automated testing.  This backend does not provide
+input.
+
+
+@subsection caveats_33 Caveats for version 3.3
+
+@subsubsection joystick_layout_33 Layout of joysticks have changed
+
+The way joystick elements are arranged have changed to match SDL2 in order to
+support SDL_GameControllerDB mappings.  The layout of joysticks may
+change again if required for compatibility with SDL2.  If you need a known and
+stable layout for game controllers, see if you can switch to @ref gamepad.
+
+Existing code that depends on a specific joystick layout will likely have to be
+updated.
+
+
+@subsubsection wait_events_33 No window required to wait for events
+
+The @ref glfwWaitEvents and @ref glfwWaitEventsTimeout functions no longer need
+a window to be created to wait for events.  Before version 3.3 these functions
+would return immediately if there were no user-created windows.  On platforms
+where only windows can receive events, an internal helper window is used.
+
+Existing code that depends on the earlier behavior will likely have to be
+updated.
+
+
+@subsubsection gamma_ramp_size_33 Gamma ramp size of 256 may be rejected
+
+The documentation for versions before 3.3 stated that a gamma ramp size of 256
+would always be accepted.  This was never the case on X11 and could lead to
+artifacts on macOS.  The @ref glfwSetGamma function has been updated to always
+generate a ramp of the correct size.
+
+Existing code that hardcodes a size of 256 should be updated to use the size of
+the current ramp of a monitor when setting a new ramp for that monitor.
+
+
+@subsubsection xinput_deadzone_33 Windows XInput deadzone removed
+
+GLFW no longer applies any deadzone to the input state received from the XInput
+API.  This was never done for any other platform joystick API so this change
+makes the behavior more consistent but you will need to apply your own deadzone
+if desired.
+
+
+@subsubsection x11_clipboard_33 X11 clipboard transfer limits
+
+GLFW now supports reading clipboard text via the `INCR` method, which removes
+the limit on how much text can be read with @ref glfwGetClipboardString.
+However, writing via this method is not yet supported, so you may not be able to
+write a very large string with @ref glfwSetClipboardString even if you read it
+from the clipboard earlier.
+
+The exact size limit for writing to the clipboard is negotiated with each
+receiving application but is at least several tens of kilobytes.  Note that only
+the read limit has changed.  Any string that could be written before still can
+be.
+
+
+@subsubsection x11_linking_33 X11 extension libraries are loaded dynamically
+
+GLFW now loads all X11 extension libraries at initialization.  The only X11
+library you need to link against is `libX11`.  The header files for the
+extension libraries are still required for compilation.
+
+Existing projects and makefiles that link GLFW directly against the extension
+libraries should still build correctly but will add these libraries as load-time
+dependencies.
+
+
+@subsubsection cmake_version_33 CMake 3.0 or later is required
+
+The minimum CMake version has been raised from 2.8.12 to 3.0.  This is only
+a requirement of the GLFW CMake files.  The GLFW source files do not depend on
+CMake.
+
+
+@subsection deprecations_33 Deprecations in version 3.3
+
+@subsubsection charmods_callback_33 Character with modifiers callback
+
+The character with modifiers callback set with @ref glfwSetCharModsCallback has
+been deprecated and should if possible not be used.
+
+Existing code should still work but further bug fixes will likely not be made.
+The callback will be removed in the next major version.
+
+
+@subsubsection clipboard_window_33 Window parameter to clipboard functions
+
+The window parameter of the clipboard functions @ref glfwGetClipboardString and
+@ref glfwSetClipboardString has been deprecated and is no longer used on any
+platform.  On platforms where the clipboard must be owned by a specific window,
+an internal helper window is used.
+
+Existing code should still work unless it depends on a specific window owning
+the clipboard.  New code may pass `NULL` as the window argument.  The parameter
+will be removed in a future release.
+
+
+@subsection removals_33 Removals in 3.3
+
+@subsubsection macos_options_33 macOS specific CMake options and macros
+
+The `GLFW_USE_RETINA`, `GLFW_USE_CHDIR` and `GLFW_USE_MENUBAR` CMake options and
+the `_GLFW_USE_RETINA`, `_GLFW_USE_CHDIR` and `_GLFW_USE_MENUBAR` compile-time
+macros have been removed.
+
+These options and macros are replaced by the window hint
+[GLFW_COCOA_RETINA_FRAMEBUFFER](@ref GLFW_COCOA_RETINA_FRAMEBUFFER_hint)
+and the init hints
+[GLFW_COCOA_CHDIR_RESOURCES](@ref GLFW_COCOA_CHDIR_RESOURCES_hint) and
+[GLFW_COCOA_MENUBAR](@ref GLFW_COCOA_MENUBAR_hint).
+
+Existing projects and makefiles that set these options or define these macros
+during compilation of GLFW will still build but it will have no effect and the
+default behaviors will be used.
+
+
+@subsubsection vulkan_sdk_33 LunarG Vulkan SDK dependency
+
+The GLFW test programs that previously depended on the LunarG Vulkan SDK now
+instead uses a Vulkan loader generated by
+[glad2](https://github.com/Dav1dde/glad).  This means the GLFW CMake files no
+longer look for the Vulkan SDK.
+
+Existing CMake projects that depended on the Vulkan SDK cache variables from
+GLFW will need to call `find_package(Vulkan)` themselves.  CMake 3.7 and later
+already comes with a
+[Vulkan find module](https://cmake.org/cmake/help/latest/module/FindVulkan.html)
+similar to the one GLFW previously included.
+
+
+@subsubsection lib_suffix_33 CMake option LIB_SUFFIX
+
+The `LIB_SUFFIX` CMake option has been removed.  GLFW now uses the
+GNUInstallDirs CMake package to handle platform specific details like the
+library directory suffix and the `LIB_SUFFIX` CMake option has been removed.
+
+Existing projects and makefiles that set the `LIB_SUFFIX` option will use the
+suffix chosen by the GNUInstallDirs package and the option will be ignored.
+
+
+@subsubsection mir_removed_33 Mir support
+
+The experimental Mir support has been completely removed as the Mir project has
+implemented support for the Wayland protocol and is recommending that
+applications use that instead.
+
+Existing projects and makefiles that select Mir when compiling GLFW will fail.
+Use Wayland or X11 instead.

+
+@subsubsection news_32_vulkan Support for Vulkan
+
+GLFW now supports basic integration with Vulkan with @ref glfwVulkanSupported,
+@ref glfwGetRequiredInstanceExtensions, @ref glfwGetInstanceProcAddress, @ref
+glfwGetPhysicalDevicePresentationSupport and @ref glfwCreateWindowSurface.
+Vulkan header inclusion can be selected with
+@ref GLFW_INCLUDE_VULKAN.
+
+
+@subsubsection news_32_setwindowmonitor Window mode switching

+
+
+@subsubsection news_32_noapi Context-less windows
+
+GLFW now supports creating windows without a OpenGL or OpenGL ES context by
+setting the [GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint) hint to `GLFW_NO_API`.
+
+
+@subsubsection news_32_contextapi Run-time context creation API selection
+
+GLFW now supports selecting and querying the context creation API at run-time
+with the @ref GLFW_CONTEXT_CREATION_API hint and attribute.
+
+
+@subsubsection news_32_noerror Error-free context creation
+
+GLFW now supports creating and querying OpenGL and OpenGL ES contexts that do

+
+These are the release notes for version 3.1.  For a more detailed view including
+all fixed bugs see the [version history](https://www.glfw.org/changelog.html).
+
+
+@subsection features_31 New features in version 3.1
+
+@subsubsection news_31_cursor Custom mouse cursor images
+
+GLFW now supports creating and setting both custom cursor images and standard
+cursor shapes.  They are created with @ref glfwCreateCursor or @ref
+glfwCreateStandardCursor, set with @ref glfwSetCursor and destroyed with @ref
+glfwDestroyCursor.
+
+@see @ref cursor_object
+
+
+@subsubsection news_31_drop Path drop event
+
+GLFW now provides a callback for receiving the paths of files and directories
+dropped onto GLFW windows.  The callback is set with @ref glfwSetDropCallback.
+
+@see @ref path_drop
+
+
+@subsubsection news_31_emptyevent Main thread wake-up
+
+GLFW now provides the @ref glfwPostEmptyEvent function for posting an empty
+event from another thread to the main thread event queue, causing @ref
+glfwWaitEvents to return.
+
+@see @ref events
+
+
+@subsubsection news_31_framesize Window frame size query
+
+GLFW now supports querying the size, on each side, of the frame around the
+content area of a window, with @ref glfwGetWindowFrameSize.
+
+@see [Window size](@ref window_size)
+
+
+@subsubsection news_31_autoiconify Simultaneous multi-monitor rendering
+
+GLFW now supports disabling auto-iconification of full screen windows with
+the [GLFW_AUTO_ICONIFY](@ref GLFW_AUTO_ICONIFY_hint) window hint.  This is
+intended for people building multi-monitor installations, where you need windows
+to stay in full screen despite losing input focus.
+
+
+@subsubsection news_31_floating Floating windows
+
+GLFW now supports floating windows, also called topmost or always on top, for
+easier debugging with the @ref GLFW_FLOATING window hint and attribute.
+
+
+@subsubsection news_31_focused Initially unfocused windows
+
+GLFW now supports preventing a windowed mode window from gaining input focus on
+creation, with the [GLFW_FOCUSED](@ref GLFW_FOCUSED_hint) window hint.
+
+
+@subsubsection news_31_direct Direct access for window attributes and cursor position
+
+GLFW now queries the window input focus, visibility and iconification attributes
+and the cursor position directly instead of returning cached data.
+
+
+@subsubsection news_31_charmods Character with modifiers callback
+
+GLFW now provides a callback for character events with modifier key bits.  The
+callback is set with @ref glfwSetCharModsCallback.  Unlike the regular character
+callback, this will report character events that will not result in a character
+being input, for example if the Control key is held down.
+
+@see @ref input_char
+
+
+@subsubsection news_31_single Single buffered framebuffers
+
+GLFW now supports the creation of single buffered windows, with the @ref
+GLFW_DOUBLEBUFFER hint.
+
+
+@subsubsection news_31_glext Macro for including extension header
+
+GLFW now includes the extension header appropriate for the chosen OpenGL or
+OpenGL ES header when @ref GLFW_INCLUDE_GLEXT is defined.  GLFW does not provide
+these headers.  They must be provided by your development environment or your
+OpenGL or OpenGL ES SDK.
+
+
+@subsubsection news_31_release Context release behaviors
+
+GLFW now supports controlling and querying whether the pipeline is flushed when
+a context is made non-current, with the @ref GLFW_CONTEXT_RELEASE_BEHAVIOR hint
+and attribute, provided the machine supports the `GL_KHR_context_flush_control`
+extension.
+
+
+@subsubsection news_31_wayland (Experimental) Wayland support
+
+GLFW now has an _experimental_ Wayland display protocol backend that can be
+selected on Linux with a CMake option.
+
+
+@subsubsection news_31_mir (Experimental) Mir support
+
+GLFW now has an _experimental_ Mir display server backend that can be selected
+on Linux with a CMake option.
+
+
+@section news_30 Release notes for 3.0
+
+These are the release notes for version 3.0.  For a more detailed view including
+all fixed bugs see the [version history](https://www.glfw.org/changelog.html).
+
+
+@subsection features_30 New features in version 3.0
+
+@subsubsection news_30_cmake CMake build system
+
+GLFW now uses the CMake build system instead of the various makefiles and
+project files used by earlier versions.  CMake is available for all platforms
+supported by GLFW, is present in most package systems and can generate
+makefiles and/or project files for most popular development environments.
+
+For more information on how to use CMake, see the
+[CMake manual](https://cmake.org/cmake/help/documentation.html).
+
+
+@subsubsection news_30_multiwnd Multi-window support
+
+GLFW now supports the creation of multiple windows, each with their own OpenGL
+or OpenGL ES context, and all window functions now take a window handle.  Event
+callbacks are now per-window and are provided with the handle of the window that
+received the event.  The @ref glfwMakeContextCurrent function has been added to
+select which context is current on a given thread.
+
+
+@subsubsection news_30_multimon Multi-monitor support
+
+GLFW now explicitly supports multiple monitors.  They can be enumerated with
+@ref glfwGetMonitors, queried with @ref glfwGetVideoModes, @ref
+glfwGetMonitorPos, @ref glfwGetMonitorName and @ref glfwGetMonitorPhysicalSize,
+and specified at window creation to make the newly created window full screen on
+that specific monitor.
+
+
+@subsubsection news_30_unicode Unicode support
+
+All string arguments to GLFW functions and all strings returned by GLFW now use
+the UTF-8 encoding.  This includes the window title, error string, clipboard
+text, monitor and joystick names as well as the extension function arguments (as
+ASCII is a subset of UTF-8).
+
+
+@subsubsection news_30_clipboard Clipboard text I/O
+
+GLFW now supports reading and writing plain text to and from the system
+clipboard, with the @ref glfwGetClipboardString and @ref glfwSetClipboardString
+functions.
+
+
+@subsubsection news_30_gamma Gamma ramp support
+
+GLFW now supports setting and reading back the gamma ramp of monitors, with the
+@ref glfwGetGammaRamp and @ref glfwSetGammaRamp functions.  There is also @ref
+glfwSetGamma, which generates a ramp from a gamma value and then sets it.
+
+
+@subsubsection news_30_gles OpenGL ES support
+
+GLFW now supports the creation of OpenGL ES contexts, by setting the
+[GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint) hint to `GLFW_OPENGL_ES_API`, where
+creation of such contexts are supported.  Note that GLFW _does not implement_
+OpenGL ES, so your driver must provide support in a way usable by GLFW.  Modern
+Nvidia and Intel drivers support creation of OpenGL ES context using the GLX and
+WGL APIs, while AMD provides an EGL implementation instead.
+
+
+@subsubsection news_30_egl (Experimental) EGL support
+
+GLFW now has an experimental EGL context creation back end that can be selected
+through CMake options.
+
+
+@subsubsection news_30_hidpi High-DPI support
+
+GLFW now supports high-DPI monitors on both Windows and macOS, giving windows
+full resolution framebuffers where other UI elements are scaled up.  To achieve
+this, @ref glfwGetFramebufferSize and @ref glfwSetFramebufferSizeCallback have
+been added.  These work with pixels, while the rest of the GLFW API works with
+screen coordinates.  This is important as OpenGL uses pixels, not screen
+coordinates.
+
+
+@subsubsection news_30_error Error callback
+
+GLFW now has an error callback, which can provide your application with much
+more detailed diagnostics than was previously possible.  The callback is passed
+an error code and a description string.
+
+
+@subsubsection news_30_wndptr Per-window user pointer
+
+Each window now has a user-defined pointer, retrieved with @ref
+glfwGetWindowUserPointer and set with @ref glfwSetWindowUserPointer, to make it
+easier to integrate GLFW into C++ code.
+
+
+@subsubsection news_30_iconifyfun Window iconification callback
+
+Each window now has a callback for iconification and restoration events,
+which is set with @ref glfwSetWindowIconifyCallback.
+
+
+@subsubsection news_30_wndposfun Window position callback
+
+Each window now has a callback for position events, which is set with @ref
+glfwSetWindowPosCallback.
+
+
+@subsubsection news_30_wndpos Window position query
+
+The position of a window can now be retrieved using @ref glfwGetWindowPos.
+
+
+@subsubsection news_30_focusfun Window focus callback
+
+Each windows now has a callback for focus events, which is set with @ref
+glfwSetWindowFocusCallback.
+
+
+@subsubsection news_30_enterleave Cursor enter/leave callback
+
+Each window now has a callback for when the mouse cursor enters or leaves its
+content area, which is set with @ref glfwSetCursorEnterCallback.
+
+
+@subsubsection news_30_wndtitle Initial window title
+
+The title of a window is now specified at creation time, as one of the arguments
+to @ref glfwCreateWindow.
+
+
+@subsubsection news_30_hidden Hidden windows
+
+Windows can now be hidden with @ref glfwHideWindow, shown using @ref
+glfwShowWindow and created initially hidden with the @ref GLFW_VISIBLE window
+hint and attribute.  This allows for off-screen rendering in a way compatible
+with most drivers, as well as moving a window to a specific position before
+showing it.
+
+
+@subsubsection news_30_undecorated Undecorated windows
+
+Windowed mode windows can now be created without decorations, e.g. things like
+a frame, a title bar, with the @ref GLFW_DECORATED window hint and attribute.
+This allows for the creation of things like splash screens.
+
+
+@subsubsection news_30_keymods Modifier key bit masks
+
+[Modifier key bit mask](@ref mods) parameters have been added to the
+[mouse button](@ref GLFWmousebuttonfun) and [key](@ref GLFWkeyfun) callbacks.
+
+
+@subsubsection news_30_scancode Platform-specific scancodes
+
+A scancode parameter has been added to the [key callback](@ref GLFWkeyfun). Keys
+that don't have a [key token](@ref keys) still get passed on with the key
+parameter set to `GLFW_KEY_UNKNOWN`.  These scancodes will vary between machines
+and are intended to be used for key bindings.
+
+
+@subsubsection news_30_jsname Joystick names
+
+The name of a joystick can now be retrieved using @ref glfwGetJoystickName.
+
+
+@subsubsection news_30_doxygen Doxygen documentation

+
+@page quick_guide Getting started
+
+@tableofcontents
+
+This guide takes you through writing a simple application using GLFW 3.  The
+application will create a window and OpenGL context, render a rotating triangle
+and exit when the user closes the window or presses _Escape_.  This guide will
+introduce a few of the most commonly used functions, but there are many more.
+
+This guide assumes no experience with earlier versions of GLFW.  If you
+have used GLFW 2 in the past, read @ref moving_guide, as some functions
+behave differently in GLFW 3.
+
+
+@section quick_steps Step by step
+
+@subsection quick_include Including the GLFW header
+
+In the source files of your application where you use OpenGL or GLFW, you need
+to include the GLFW 3 header file.
+
+@code
+#include <GLFW/glfw3.h>
+@endcode
+
+This defines all the constants, types and function prototypes of the GLFW API.
+It also includes the OpenGL header from your development environment and
+defines all the constants and types necessary for it to work on your platform
+without including any platform-specific headers.
+
+In other words:
+
+- Do _not_ include the OpenGL header yourself, as GLFW does this for you in
+  a platform-independent way
+- Do _not_ include `windows.h` or other platform-specific headers unless
+  you plan on using those APIs yourself
+- If you _do_ need to include such headers, include them _before_ the GLFW
+  header and it will detect this
+
+On some platforms supported by GLFW the OpenGL header and link library only
+expose older versions of OpenGL.  The most extreme case is Windows, which only
+exposes OpenGL 1.2.  The easiest way to work around this is to use an
+[extension loader library](@ref context_glext_auto).
+
+If you are using such a library then you should include its header _before_ the
+GLFW header.  This lets it replace the OpenGL header included by GLFW without
+conflicts.  This example uses
+[glad2](https://github.com/Dav1dde/glad), but the same rule applies to all such
+libraries.
+
+@code
+#include <glad/gl.h>
+#include <GLFW/glfw3.h>
+@endcode
+
+
+@subsection quick_init_term Initializing and terminating GLFW
+
+Before you can use most GLFW functions, the library must be initialized.  On
+successful initialization, `GLFW_TRUE` is returned.  If an error occurred,
+`GLFW_FALSE` is returned.
+
+@code
+if (!glfwInit())
+{
+    // Initialization failed
+}
+@endcode
+
+Note that `GLFW_TRUE` and `GLFW_FALSE` are and will always be one and zero.
+
+When you are done using GLFW, typically just before the application exits, you
+need to terminate GLFW.
+
+@code
+glfwTerminate();
+@endcode
+
+This destroys any remaining windows and releases any other resources allocated by
+GLFW.  After this call, you must initialize GLFW again before using any GLFW
+functions that require it.
+
+
+@subsection quick_capture_error Setting an error callback
+
+Most events are reported through callbacks, whether it's a key being pressed,
+a GLFW window being moved, or an error occurring.  Callbacks are C functions (or
+C++ static methods) that are called by GLFW with arguments describing the event.
+
+In case a GLFW function fails, an error is reported to the GLFW error callback.
+You can receive these reports with an error callback.  This function must have
+the signature below but may do anything permitted in other callbacks.
+
+@code
+void error_callback(int error, const char* description)
+{
+    fprintf(stderr, "Error: %s\n", description);
+}
+@endcode
+
+Callback functions must be set, so GLFW knows to call them.  The function to set
+the error callback is one of the few GLFW functions that may be called before
+initialization, which lets you be notified of errors both during and after
+initialization.
+
+@code
+glfwSetErrorCallback(error_callback);
+@endcode
+
+
+@subsection quick_create_window Creating a window and context
+
+The window and its OpenGL context are created with a single call to @ref
+glfwCreateWindow, which returns a handle to the created combined window and
+context object
+
+@code
+GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL);
+if (!window)
+{
+    // Window or OpenGL context creation failed
+}
+@endcode
+
+This creates a 640 by 480 windowed mode window with an OpenGL context.  If
+window or OpenGL context creation fails, `NULL` will be returned.  You should
+always check the return value.  While window creation rarely fails, context
+creation depends on properly installed drivers and may fail even on machines
+with the necessary hardware.
+
+By default, the OpenGL context GLFW creates may have any version.  You can
+require a minimum OpenGL version by setting the `GLFW_CONTEXT_VERSION_MAJOR` and
+`GLFW_CONTEXT_VERSION_MINOR` hints _before_ creation.  If the required minimum
+version is not supported on the machine, context (and window) creation fails.
+
+@code
+glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 2);
+glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 0);
+GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL);
+if (!window)
+{
+    // Window or context creation failed
+}
+@endcode
+
+The window handle is passed to all window related functions and is provided to
+along to all window related callbacks, so they can tell which window received
+the event.
+
+When a window and context is no longer needed, destroy it.
+
+@code
+glfwDestroyWindow(window);
+@endcode
+
+Once this function is called, no more events will be delivered for that window
+and its handle becomes invalid.
+
+
+@subsection quick_context_current Making the OpenGL context current
+
+Before you can use the OpenGL API, you must have a current OpenGL context.
+
+@code
+glfwMakeContextCurrent(window);
+@endcode
+
+The context will remain current until you make another context current or until
+the window owning the current context is destroyed.
+
+If you are using an [extension loader library](@ref context_glext_auto) to
+access modern OpenGL then this is when to initialize it, as the loader needs
+a current context to load from.  This example uses
+[glad](https://github.com/Dav1dde/glad), but the same rule applies to all such
+libraries.
+
+@code
+gladLoadGL(glfwGetProcAddress);
+@endcode
+
+
+@subsection quick_window_close Checking the window close flag
+
+Each window has a flag indicating whether the window should be closed.
+
+When the user attempts to close the window, either by pressing the close widget
+in the title bar or using a key combination like Alt+F4, this flag is set to 1.
+Note that __the window isn't actually closed__, so you are expected to monitor
+this flag and either destroy the window or give some kind of feedback to the
+user.
+
+@code
+while (!glfwWindowShouldClose(window))
+{
+    // Keep running
+}
+@endcode
+
+You can be notified when the user is attempting to close the window by setting
+a close callback with @ref glfwSetWindowCloseCallback.  The callback will be
+called immediately after the close flag has been set.
+
+You can also set it yourself with @ref glfwSetWindowShouldClose.  This can be
+useful if you want to interpret other kinds of input as closing the window, like
+for example pressing the _Escape_ key.
+
+
+@subsection quick_key_input Receiving input events
+
+Each window has a large number of callbacks that can be set to receive all the
+various kinds of events.  To receive key press and release events, create a key
+callback function.
+
+@code
+static void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods)
+{
+    if (key == GLFW_KEY_ESCAPE && action == GLFW_PRESS)
+        glfwSetWindowShouldClose(window, GLFW_TRUE);
+}
+@endcode
+
+The key callback, like other window related callbacks, are set per-window.
+
+@code
+glfwSetKeyCallback(window, key_callback);
+@endcode
+
+In order for event callbacks to be called when events occur, you need to process
+events as described below.
+
+
+@subsection quick_render Rendering with OpenGL
+
+Once you have a current OpenGL context, you can use OpenGL normally.  In this
+tutorial, a multi-colored rotating triangle will be rendered.  The framebuffer
+size needs to be retrieved for `glViewport`.
+
+@code
+int width, height;
+glfwGetFramebufferSize(window, &width, &height);
+glViewport(0, 0, width, height);
+@endcode
+
+You can also set a framebuffer size callback using @ref
+glfwSetFramebufferSizeCallback and be notified when the size changes.
+
+Actual rendering with OpenGL is outside the scope of this tutorial, but there
+are [many](https://open.gl/) [excellent](https://learnopengl.com/)
+[tutorial](http://openglbook.com/) [sites](http://ogldev.atspace.co.uk/) that
+teach modern OpenGL.  Some of them use GLFW to create the context and window
+while others use GLUT or SDL, but remember that OpenGL itself always works the
+same.
+
+
+@subsection quick_timer Reading the timer
+
+To create smooth animation, a time source is needed.  GLFW provides a timer that
+returns the number of seconds since initialization.  The time source used is the
+most accurate on each platform and generally has micro- or nanosecond
+resolution.
+
+@code
+double time = glfwGetTime();
+@endcode
+
+
+@subsection quick_swap_buffers Swapping buffers
+
+GLFW windows by default use double buffering.  That means that each window has
+two rendering buffers; a front buffer and a back buffer.  The front buffer is
+the one being displayed and the back buffer the one you render to.
+
+When the entire frame has been rendered, the buffers need to be swapped with one
+another, so the back buffer becomes the front buffer and vice versa.
+
+@code
+glfwSwapBuffers(window);
+@endcode
+
+The swap interval indicates how many frames to wait until swapping the buffers,
+commonly known as _vsync_.  By default, the swap interval is zero, meaning
+buffer swapping will occur immediately.  On fast machines, many of those frames
+will never be seen, as the screen is still only updated typically 60-75 times
+per second, so this wastes a lot of CPU and GPU cycles.
+
+Also, because the buffers will be swapped in the middle the screen update,
+leading to [screen tearing](https://en.wikipedia.org/wiki/Screen_tearing).
+
+For these reasons, applications will typically want to set the swap interval to
+one.  It can be set to higher values, but this is usually not recommended,
+because of the input latency it leads to.
+
+@code
+glfwSwapInterval(1);
+@endcode
+
+This function acts on the current context and will fail unless a context is
+current.
+
+
+@subsection quick_process_events Processing events
+
+GLFW needs to communicate regularly with the window system both in order to
+receive events and to show that the application hasn't locked up.  Event
+processing must be done regularly while you have visible windows and is normally
+done each frame after buffer swapping.
+
+There are two methods for processing pending events; polling and waiting.  This
+example will use event polling, which processes only those events that have
+already been received and then returns immediately.
+
+@code
+glfwPollEvents();
+@endcode
+
+This is the best choice when rendering continually, like most games do.  If
+instead you only need to update your rendering once you have received new input,
+@ref glfwWaitEvents is a better choice.  It waits until at least one event has
+been received, putting the thread to sleep in the meantime, and then processes
+all received events.  This saves a great deal of CPU cycles and is useful for,
+for example, many kinds of editing tools.
+
+
+@section quick_example Putting it together
+
+Now that you know how to initialize GLFW, create a window and poll for
+keyboard input, it's possible to create a simple program.
+
+This program creates a 640 by 480 windowed mode window and starts a loop that
+clears the screen, renders a triangle and processes events until the user either
+presses _Escape_ or closes the window.
+
+@snippet simple.c code
+
+The program above can be found in the
+[source package](https://www.glfw.org/download.html) as `examples/simple.c`
+and is compiled along with all other examples when you build GLFW.  If you
+built GLFW from the source package then you already have this as `simple.exe` on
+Windows, `simple` on Linux or `simple.app` on macOS.
+
+This tutorial used only a few of the many functions GLFW provides.  There are
+guides for each of the areas covered by GLFW.  Each guide will introduce all the
+functions for that category.
+
+ - @ref intro_guide
+ - @ref window_guide
+ - @ref context_guide
+ - @ref monitor_guide
+ - @ref input_guide
+
+You can access reference documentation for any GLFW function by clicking it and
+the reference for each function links to related functions and guide sections.
+
+The tutorial ends here.  Once you have written a program that uses GLFW, you
+will need to compile and link it.  How to do that depends on the development
+environment you are using and is best explained by the documentation for that
+environment.  To learn about the details that are specific to GLFW, see
+@ref build_guide.

+@page vulkan_guide Vulkan guide
+
+@tableofcontents
+
+This guide is intended to fill the gaps between the [Vulkan
+documentation](https://www.khronos.org/vulkan/) and the rest of the GLFW
+documentation and is not a replacement for either.  It assumes some familiarity
+with Vulkan concepts like loaders, devices, queues and surfaces and leaves it to
+the Vulkan documentation to explain the details of Vulkan functions.
+
+To develop for Vulkan you should download the [LunarG Vulkan
+SDK](https://vulkan.lunarg.com/) for your platform.  Apart from headers and link
+libraries, they also provide the validation layers necessary for development.
+
+For details on a specific function in this category, see the @ref vulkan.  There
+are also guides for the other areas of the GLFW API.
+
+ - @ref intro_guide
+ - @ref window_guide
+ - @ref context_guide
+ - @ref monitor_guide
+ - @ref input_guide
+
+
+@section vulkan_loader Linking against the Vulkan loader
+
+By default, GLFW will look for the Vulkan loader on demand at runtime via its
+standard name (`vulkan-1.dll` on Windows, `libvulkan.so.1` on Linux and other
+Unix-like systems and `libvulkan.1.dylib` on macOS).  This means that GLFW does
+not need to be linked against the loader.  However, it also means that if you
+are using the static library form of the Vulkan loader GLFW will either fail to
+find it or (worse) use the wrong one.
+
+The @ref GLFW_VULKAN_STATIC CMake option makes GLFW call the Vulkan loader
+directly instead of dynamically loading it at runtime.  Not linking against the
+Vulkan loader will then be a compile-time error.
+
+@macos Because the Vulkan loader and ICD are not installed globally on macOS,
+you need to set up the application bundle according to the LunarG SDK
+documentation.  This is explained in more detail in the
+[SDK documentation for macOS](https://vulkan.lunarg.com/doc/sdk/latest/mac/getting_started.html).
+
+
+@section vulkan_include Including the Vulkan and GLFW header files
+
+To include the Vulkan header, define @ref GLFW_INCLUDE_VULKAN before including
+the GLFW header.
+
+@code
+#define GLFW_INCLUDE_VULKAN
+#include <GLFW/glfw3.h>
+@endcode
+
+If you instead want to include the Vulkan header from a custom location or use
+your own custom Vulkan header then do this before the GLFW header.
+
+@code
+#include <path/to/vulkan.h>
+#include <GLFW/glfw3.h>
+@endcode
+
+Unless a Vulkan header is included, either by the GLFW header or above it, any
+GLFW functions that take or return Vulkan types will not be declared.
+
+The `VK_USE_PLATFORM_*_KHR` macros do not need to be defined for the Vulkan part
+of GLFW to work.  Define them only if you are using these extensions directly.
+
+
+@section vulkan_support Querying for Vulkan support
+
+If you are linking directly against the Vulkan loader then you can skip this
+section.  The canonical desktop loader library exports all Vulkan core and
+Khronos extension functions, allowing them to be called directly.
+
+If you are loading the Vulkan loader dynamically instead of linking directly
+against it, you can check for the availability of a loader and ICD with @ref
+glfwVulkanSupported.
+
+@code
+if (glfwVulkanSupported())
+{
+    // Vulkan is available, at least for compute
+}
+@endcode
+
+This function returns `GLFW_TRUE` if the Vulkan loader and any minimally
+functional ICD was found.
+
+If if one or both were not found, calling any other Vulkan related GLFW function
+will generate a @ref GLFW_API_UNAVAILABLE error.
+
+
+@subsection vulkan_proc Querying Vulkan function pointers
+
+To load any Vulkan core or extension function from the found loader, call @ref
+glfwGetInstanceProcAddress.  To load functions needed for instance creation,
+pass `NULL` as the instance.
+
+@code
+PFN_vkCreateInstance pfnCreateInstance = (PFN_vkCreateInstance)
+    glfwGetInstanceProcAddress(NULL, "vkCreateInstance");
+@endcode
+
+Once you have created an instance, you can load from it all other Vulkan core
+functions and functions from any instance extensions you enabled.
+
+@code
+PFN_vkCreateDevice pfnCreateDevice = (PFN_vkCreateDevice)
+    glfwGetInstanceProcAddress(instance, "vkCreateDevice");
+@endcode
+
+This function in turn calls `vkGetInstanceProcAddr`.  If that fails, the
+function falls back to a platform-specific query of the Vulkan loader (i.e.
+`dlsym` or `GetProcAddress`).  If that also fails, the function returns `NULL`.
+For more information about `vkGetInstanceProcAddr`, see the Vulkan
+documentation.
+
+Vulkan also provides `vkGetDeviceProcAddr` for loading device-specific versions
+of Vulkan function.  This function can be retrieved from an instance with @ref
+glfwGetInstanceProcAddress.
+
+@code
+PFN_vkGetDeviceProcAddr pfnGetDeviceProcAddr = (PFN_vkGetDeviceProcAddr)
+    glfwGetInstanceProcAddress(instance, "vkGetDeviceProcAddr");
+@endcode
+
+Device-specific functions may execute a little bit faster, due to not having to
+dispatch internally based on the device passed to them.  For more information
+about `vkGetDeviceProcAddr`, see the Vulkan documentation.
+
+
+@section vulkan_ext Querying required Vulkan extensions
+
+To do anything useful with Vulkan you need to create an instance.  If you want
+to use Vulkan to render to a window, you must enable the instance extensions
+GLFW requires to create Vulkan surfaces.
+
+To query the instance extensions required, call @ref
+glfwGetRequiredInstanceExtensions.
+
+@code
+uint32_t count;
+const char** extensions = glfwGetRequiredInstanceExtensions(&count);
+@endcode
+
+These extensions must all be enabled when creating instances that are going to
+be passed to @ref glfwGetPhysicalDevicePresentationSupport and @ref
+glfwCreateWindowSurface.  The set of extensions will vary depending on platform
+and may also vary depending on graphics drivers and other factors.
+
+If it fails it will return `NULL` and GLFW will not be able to create Vulkan
+window surfaces.  You can still use Vulkan for off-screen rendering and compute
+work.
+
+If successful the returned array will always include `VK_KHR_surface`, so if
+you don't require any additional extensions you can pass this list directly to
+the `VkInstanceCreateInfo` struct.
+
+@code
+VkInstanceCreateInfo ici;
+
+memset(&ici, 0, sizeof(ici));
+ici.enabledExtensionCount = count;
+ici.ppEnabledExtensionNames = extensions;
+...
+@endcode
+
+Additional extensions may be required by future versions of GLFW.  You should
+check whether any extensions you wish to enable are already in the returned
+array, as it is an error to specify an extension more than once in the
+`VkInstanceCreateInfo` struct.
+
+
+@section vulkan_present Querying for Vulkan presentation support
+
+Not every queue family of every Vulkan device can present images to surfaces.
+To check whether a specific queue family of a physical device supports image
+presentation without first having to create a window and surface, call @ref
+glfwGetPhysicalDevicePresentationSupport.
+
+@code
+if (glfwGetPhysicalDevicePresentationSupport(instance, physical_device, queue_family_index))
+{
+    // Queue family supports image presentation
+}
+@endcode
+
+The `VK_KHR_surface` extension additionally provides the
+`vkGetPhysicalDeviceSurfaceSupportKHR` function, which performs the same test on
+an existing Vulkan surface.
+
+
+@section vulkan_window Creating the window
+
+Unless you will be using OpenGL or OpenGL ES with the same window as Vulkan,
+there is no need to create a context.  You can disable context creation with the
+[GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint) hint.
+
+@code
+glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API);
+GLFWwindow* window = glfwCreateWindow(640, 480, "Window Title", NULL, NULL);
+@endcode
+
+See @ref context_less for more information.
+
+
+@section vulkan_surface Creating a Vulkan window surface
+
+You can create a Vulkan surface (as defined by the `VK_KHR_surface` extension)
+for a GLFW window with @ref glfwCreateWindowSurface.
+
+@code
+VkSurfaceKHR surface;
+VkResult err = glfwCreateWindowSurface(instance, window, NULL, &surface);
+if (err)
+{
+    // Window surface creation failed
+}
+@endcode
+
+If an OpenGL or OpenGL ES context was created on the window, the context has
+ownership of the presentation on the window and a Vulkan surface cannot be
+created.
+
+It is your responsibility to destroy the surface.  GLFW does not destroy it for
+you.  Call `vkDestroySurfaceKHR` function from the same extension to destroy it.

+
+@page window_guide Window guide
+
+@tableofcontents
+
+This guide introduces the window related functions of GLFW.  For details on
+a specific function in this category, see the @ref window.  There are also
+guides for the other areas of GLFW.
+
+ - @ref intro_guide
+ - @ref context_guide
+ - @ref vulkan_guide
+ - @ref monitor_guide
+ - @ref input_guide
+
+
+@section window_object Window objects
+
+The @ref GLFWwindow object encapsulates both a window and a context.  They are
+created with @ref glfwCreateWindow and destroyed with @ref glfwDestroyWindow, or
+@ref glfwTerminate, if any remain.  As the window and context are inseparably
+linked, the object pointer is used as both a context and window handle.
+
+To see the event stream provided to the various window related callbacks, run
+the `events` test program.
+
+
+@subsection window_creation Window creation
+
+A window and its OpenGL or OpenGL ES context are created with @ref
+glfwCreateWindow, which returns a handle to the created window object.  For
+example, this creates a 640 by 480 windowed mode window:
+
+@code
+GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL);
+@endcode
+
+If window creation fails, `NULL` will be returned, so it is necessary to check
+the return value.
+
+The window handle is passed to all window related functions and is provided to
+along with all input events, so event handlers can tell which window received
+the event.
+
+
+@subsubsection window_full_screen Full screen windows
+
+To create a full screen window, you need to specify which monitor the window
+should use.  In most cases, the user's primary monitor is a good choice.
+For more information about retrieving monitors, see @ref monitor_monitors.
+
+@code
+GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", glfwGetPrimaryMonitor(), NULL);
+@endcode
+
+Full screen windows cover the entire display area of a monitor, have no border
+or decorations.
+
+Windowed mode windows can be made full screen by setting a monitor with @ref
+glfwSetWindowMonitor, and full screen ones can be made windowed by unsetting it
+with the same function.
+
+Each field of the @ref GLFWvidmode structure corresponds to a function parameter
+or window hint and combine to form the _desired video mode_ for that window.
+The supported video mode most closely matching the desired video mode will be
+set for the chosen monitor as long as the window has input focus.  For more
+information about retrieving video modes, see @ref monitor_modes.
+
+Video mode field        | Corresponds to
+----------------        | --------------
+GLFWvidmode.width       | `width` parameter of @ref glfwCreateWindow
+GLFWvidmode.height      | `height` parameter of @ref glfwCreateWindow
+GLFWvidmode.redBits     | @ref GLFW_RED_BITS hint
+GLFWvidmode.greenBits   | @ref GLFW_GREEN_BITS hint
+GLFWvidmode.blueBits    | @ref GLFW_BLUE_BITS hint
+GLFWvidmode.refreshRate | @ref GLFW_REFRESH_RATE hint
+
+Once you have a full screen window, you can change its resolution, refresh rate
+and monitor with @ref glfwSetWindowMonitor.  If you only need change its
+resolution you can also call @ref glfwSetWindowSize.  In all cases, the new
+video mode will be selected the same way as the video mode chosen by @ref
+glfwCreateWindow.  If the window has an OpenGL or OpenGL ES context, it will be
+unaffected.
+
+By default, the original video mode of the monitor will be restored and the
+window iconified if it loses input focus, to allow the user to switch back to
+the desktop.  This behavior can be disabled with the
+[GLFW_AUTO_ICONIFY](@ref GLFW_AUTO_ICONIFY_hint) window hint, for example if you
+wish to simultaneously cover multiple monitors with full screen windows.
+
+If a monitor is disconnected, all windows that are full screen on that monitor
+will be switched to windowed mode.  See @ref monitor_event for more information.
+
+
+@subsubsection window_windowed_full_screen "Windowed full screen" windows
+
+If the closest match for the desired video mode is the current one, the video
+mode will not be changed, making window creation faster and application
+switching much smoother.  This is sometimes called _windowed full screen_ or
+_borderless full screen_ window and counts as a full screen window.  To create
+such a window, request the current video mode.
+
+@code
+const GLFWvidmode* mode = glfwGetVideoMode(monitor);
+
+glfwWindowHint(GLFW_RED_BITS, mode->redBits);
+glfwWindowHint(GLFW_GREEN_BITS, mode->greenBits);
+glfwWindowHint(GLFW_BLUE_BITS, mode->blueBits);
+glfwWindowHint(GLFW_REFRESH_RATE, mode->refreshRate);
+
+GLFWwindow* window = glfwCreateWindow(mode->width, mode->height, "My Title", monitor, NULL);
+@endcode
+
+This also works for windowed mode windows that are made full screen.
+
+@code
+const GLFWvidmode* mode = glfwGetVideoMode(monitor);
+
+glfwSetWindowMonitor(window, monitor, 0, 0, mode->width, mode->height, mode->refreshRate);
+@endcode
+
+Note that @ref glfwGetVideoMode returns the _current_ video mode of a monitor,
+so if you already have a full screen window on that monitor that you want to
+make windowed full screen, you need to have saved the desktop resolution before.
+
+
+@subsection window_destruction Window destruction
+
+When a window is no longer needed, destroy it with @ref glfwDestroyWindow.
+
+@code
+glfwDestroyWindow(window);
+@endcode
+
+Window destruction always succeeds.  Before the actual destruction, all
+callbacks are removed so no further events will be delivered for the window.
+All windows remaining when @ref glfwTerminate is called are destroyed as well.
+
+When a full screen window is destroyed, the original video mode of its monitor
+is restored, but the gamma ramp is left untouched.
+
+
+@subsection window_hints Window creation hints
+
+There are a number of hints that can be set before the creation of a window and
+context.  Some affect the window itself, others affect the framebuffer or
+context.  These hints are set to their default values each time the library is
+initialized with @ref glfwInit.  Integer value hints can be set individually
+with @ref glfwWindowHint and string value hints with @ref glfwWindowHintString.
+You can reset all at once to their defaults with @ref glfwDefaultWindowHints.
+
+Some hints are platform specific.  These are always valid to set on any
+platform but they will only affect their specific platform.  Other platforms
+will ignore them.  Setting these hints requires no platform specific headers or
+calls.
+
+@note Window hints need to be set before the creation of the window and context
+you wish to have the specified attributes.  They function as additional
+arguments to @ref glfwCreateWindow.
+
+
+@subsubsection window_hints_hard Hard and soft constraints
+
+Some window hints are hard constraints.  These must match the available
+capabilities _exactly_ for window and context creation to succeed.  Hints
+that are not hard constraints are matched as closely as possible, but the
+resulting context and framebuffer may differ from what these hints requested.
+
+The following hints are always hard constraints:
+- @ref GLFW_STEREO
+- @ref GLFW_DOUBLEBUFFER
+- [GLFW_CLIENT_API](@ref GLFW_CLIENT_API_hint)
+- [GLFW_CONTEXT_CREATION_API](@ref GLFW_CONTEXT_CREATION_API_hint)
+
+The following additional hints are hard constraints when requesting an OpenGL
+context, but are ignored when requesting an OpenGL ES context:
+- [GLFW_OPENGL_FORWARD_COMPAT](@ref GLFW_OPENGL_FORWARD_COMPAT_hint)
+- [GLFW_OPENGL_PROFILE](@ref GLFW_OPENGL_PROFILE_hint)
+
+
+@subsubsection window_hints_wnd Window related hints
+
+@anchor GLFW_RESIZABLE_hint
+__GLFW_RESIZABLE__ specifies whether the windowed mode window will be resizable

+Possible values are `GLFW_TRUE` and `GLFW_FALSE`.  This hint is ignored for
+windowed mode windows.
+
+@anchor GLFW_FLOATING_hint
+__GLFW_FLOATING__ specifies whether the windowed mode window will be floating
+above other regular windows, also called topmost or always-on-top.  This is

+
+@anchor GLFW_TRANSPARENT_FRAMEBUFFER_hint
+__GLFW_TRANSPARENT_FRAMEBUFFER__ specifies whether the window framebuffer will
+be transparent.  If enabled and supported by the system, the window framebuffer
+alpha channel will be used to combine the framebuffer with the background.  This
+does not affect window decorations.  Possible values are `GLFW_TRUE` and
+`GLFW_FALSE`.
+
+@par
+@win32 GLFW sets a color key for the window to work around repainting issues
+with a transparent framebuffer.  The chosen color value is RGB 255,0,255
+(magenta).  This will make pixels with that exact color fully transparent
+regardless of their alpha values.  If this is a problem, make these pixels any
+other color before buffer swap.
+
+@anchor GLFW_FOCUS_ON_SHOW_hint
+__GLFW_FOCUS_ON_SHOW__ specifies whether the window will be given input
+focus when @ref glfwShowWindow is called. Possible values are `GLFW_TRUE` and `GLFW_FALSE`.

+@anchor GLFW_SCALE_TO_MONITOR
+__GLFW_SCALE_TO_MONITOR__ specified whether the window content area should be
+resized based on the [monitor content scale](@ref monitor_scale) of any monitor
+it is placed on.  This includes the initial placement when the window is
+created.  Possible values are `GLFW_TRUE` and `GLFW_FALSE`.

+@section window_events Window event processing
+
+See @ref events.
+
+
+@section window_properties Window properties and events
+
+@subsection window_userptr User pointer
+
+Each window has a user pointer that can be set with @ref
+glfwSetWindowUserPointer and queried with @ref glfwGetWindowUserPointer.  This
+can be used for any purpose you need and will not be modified by GLFW throughout
+the life-time of the window.
+
+The initial value of the pointer is `NULL`.
+
+
+@subsection window_close Window closing and close flag
+
+When the user attempts to close the window, for example by clicking the close
+widget or using a key chord like Alt+F4, the _close flag_ of the window is set.
+The window is however not actually destroyed and, unless you watch for this
+state change, nothing further happens.
+
+The current state of the close flag is returned by @ref glfwWindowShouldClose
+and can be set or cleared directly with @ref glfwSetWindowShouldClose.  A common
+pattern is to use the close flag as a main loop condition.
+
+@code
+while (!glfwWindowShouldClose(window))
+{
+    render(window);
+
+    glfwSwapBuffers(window);
+    glfwPollEvents();
+}
+@endcode
+
+If you wish to be notified when the user attempts to close a window, set a close
+callback.
+
+@code
+glfwSetWindowCloseCallback(window, window_close_callback);
+@endcode
+
+The callback function is called directly _after_ the close flag has been set.
+It can be used for example to filter close requests and clear the close flag
+again unless certain conditions are met.
+
+@code
+void window_close_callback(GLFWwindow* window)
+{
+    if (!time_to_close)
+        glfwSetWindowShouldClose(window, GLFW_FALSE);
+}
+@endcode
+
+
+@subsection window_size Window size
+
+The size of a window can be changed with @ref glfwSetWindowSize.  For windowed
+mode windows, this sets the size, in
+[screen coordinates](@ref coordinate_systems) of the _content area_ or _content
+area_ of the window.  The window system may impose limits on window size.
+
+@code
+glfwSetWindowSize(window, 640, 480);
+@endcode
+
+For full screen windows, the specified size becomes the new resolution of the
+window's desired video mode.  The video mode most closely matching the new
+desired video mode is set immediately.  The window is resized to fit the
+resolution of the set video mode.
+
+If you wish to be notified when a window is resized, whether by the user, the
+system or your own code, set a size callback.
+
+@code
+glfwSetWindowSizeCallback(window, window_size_callback);
+@endcode
+
+The callback function receives the new size, in screen coordinates, of the
+content area of the window when the window is resized.
+
+@code
+void window_size_callback(GLFWwindow* window, int width, int height)
+{
+}
+@endcode
+
+There is also @ref glfwGetWindowSize for directly retrieving the current size of
+a window.
+
+@code
+int width, height;
+glfwGetWindowSize(window, &width, &height);
+@endcode
+
+@note Do not pass the window size to `glViewport` or other pixel-based OpenGL
+calls.  The window size is in screen coordinates, not pixels.  Use the
+[framebuffer size](@ref window_fbsize), which is in pixels, for pixel-based
+calls.
+
+The above functions work with the size of the content area, but decorated
+windows typically have title bars and window frames around this rectangle.  You
+can retrieve the extents of these with @ref glfwGetWindowFrameSize.
+
+@code
+int left, top, right, bottom;
+glfwGetWindowFrameSize(window, &left, &top, &right, &bottom);
+@endcode
+
+The returned values are the distances, in screen coordinates, from the edges of
+the content area to the corresponding edges of the full window.  As they are
+distances and not coordinates, they are always zero or positive.
+
+
+@subsection window_fbsize Framebuffer size
+
+While the size of a window is measured in screen coordinates, OpenGL works with
+pixels.  The size you pass into `glViewport`, for example, should be in pixels.
+On some machines screen coordinates and pixels are the same, but on others they
+will not be.  There is a second set of functions to retrieve the size, in
+pixels, of the framebuffer of a window.
+
+If you wish to be notified when the framebuffer of a window is resized, whether
+by the user or the system, set a size callback.
+
+@code
+glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);
+@endcode
+
+The callback function receives the new size of the framebuffer when it is
+resized, which can for example be used to update the OpenGL viewport.
+
+@code
+void framebuffer_size_callback(GLFWwindow* window, int width, int height)
+{
+    glViewport(0, 0, width, height);
+}
+@endcode
+
+There is also @ref glfwGetFramebufferSize for directly retrieving the current
+size of the framebuffer of a window.
+
+@code
+int width, height;
+glfwGetFramebufferSize(window, &width, &height);
+glViewport(0, 0, width, height);
+@endcode
+
+The size of a framebuffer may change independently of the size of a window, for
+example if the window is dragged between a regular monitor and a high-DPI one.
+
+
+@subsection window_scale Window content scale
+
+The content scale for a window can be retrieved with @ref
+glfwGetWindowContentScale.
+
+@code
+float xscale, yscale;
+glfwGetWindowContentScale(window, &xscale, &yscale);
+@endcode
+
+The content scale is the ratio between the current DPI and the platform's
+default DPI.  This is especially important for text and any UI elements.  If the
+pixel dimensions of your UI scaled by this look appropriate on your machine then
+it should appear at a reasonable size on other machines regardless of their DPI
+and scaling settings.  This relies on the system DPI and scaling settings being
+somewhat correct.
+
+On systems where each monitors can have its own content scale, the window
+content scale will depend on which monitor the system considers the window to be
+on.
+
+If you wish to be notified when the content scale of a window changes, whether
+because of a system setting change or because it was moved to a monitor with
+a different scale, set a content scale callback.
+
+@code
+glfwSetWindowContentScaleCallback(window, window_content_scale_callback);
+@endcode
+
+The callback function receives the new content scale of the window.
+
+@code
+void window_content_scale_callback(GLFWwindow* window, float xscale, float yscale)
+{
+    set_interface_scale(xscale, yscale);
+}
+@endcode
+
+On platforms where pixels and screen coordinates always map 1:1, the window
+will need to be resized to appear the same size when it is moved to a monitor
+with a different content scale.  To have this done automatically both when the
+window is created and when its content scale later changes, set the @ref
+GLFW_SCALE_TO_MONITOR window hint.
+
+
+@subsection window_sizelimits Window size limits
+
+The minimum and maximum size of the content area of a windowed mode window can
+be enforced with @ref glfwSetWindowSizeLimits.  The user may resize the window
+to any size and aspect ratio within the specified limits, unless the aspect
+ratio is also set.
+
+@code
+glfwSetWindowSizeLimits(window, 200, 200, 400, 400);
+@endcode
+
+To specify only a minimum size or only a maximum one, set the other pair to
+`GLFW_DONT_CARE`.
+
+@code
+glfwSetWindowSizeLimits(window, 640, 480, GLFW_DONT_CARE, GLFW_DONT_CARE);
+@endcode
+
+To disable size limits for a window, set them all to `GLFW_DONT_CARE`.
+
+The aspect ratio of the content area of a windowed mode window can be enforced
+with @ref glfwSetWindowAspectRatio.  The user may resize the window freely
+unless size limits are also set, but the size will be constrained to maintain
+the aspect ratio.
+
+@code
+glfwSetWindowAspectRatio(window, 16, 9);
+@endcode
+
+The aspect ratio is specified as a numerator and denominator, corresponding to
+the width and height, respectively.  If you want a window to maintain its
+current aspect ratio, use its current size as the ratio.
+
+@code
+int width, height;
+glfwGetWindowSize(window, &width, &height);
+glfwSetWindowAspectRatio(window, width, height);
+@endcode
+
+To disable the aspect ratio limit for a window, set both terms to
+`GLFW_DONT_CARE`.
+
+You can have both size limits and aspect ratio set for a window, but the results
+are undefined if they conflict.
+
+
+@subsection window_pos Window position
+
+The position of a windowed-mode window can be changed with @ref
+glfwSetWindowPos.  This moves the window so that the upper-left corner of its
+content area has the specified [screen coordinates](@ref coordinate_systems).
+The window system may put limitations on window placement.
+
+@code
+glfwSetWindowPos(window, 100, 100);
+@endcode
+
+If you wish to be notified when a window is moved, whether by the user, the
+system or your own code, set a position callback.
+
+@code
+glfwSetWindowPosCallback(window, window_pos_callback);
+@endcode
+
+The callback function receives the new position, in screen coordinates, of the
+upper-left corner of the content area when the window is moved.
+
+@code
+void window_pos_callback(GLFWwindow* window, int xpos, int ypos)
+{
+}
+@endcode
+
+There is also @ref glfwGetWindowPos for directly retrieving the current position
+of the content area of the window.
+
+@code
+int xpos, ypos;
+glfwGetWindowPos(window, &xpos, &ypos);
+@endcode
+
+
+@subsection window_title Window title
+
+All GLFW windows have a title, although undecorated or full screen windows may
+not display it or only display it in a task bar or similar interface.  You can
+set a UTF-8 encoded window title with @ref glfwSetWindowTitle.
+
+@code
+glfwSetWindowTitle(window, "My Window");
+@endcode
+
+The specified string is copied before the function returns, so there is no need
+to keep it around.
+
+As long as your source file is encoded as UTF-8, you can use any Unicode
+characters directly in the source.
+
+@code
+glfwSetWindowTitle(window, "ラストエグザイル");
+@endcode
+
+If you are using C++11 or C11, you can use a UTF-8 string literal.
+
+@code
+glfwSetWindowTitle(window, u8"This is always a UTF-8 string");
+@endcode
+
+
+@subsection window_icon Window icon
+
+Decorated windows have icons on some platforms.  You can set this icon by
+specifying a list of candidate images with @ref glfwSetWindowIcon.
+
+@code
+GLFWimage images[2];
+images[0] = load_icon("my_icon.png");
+images[1] = load_icon("my_icon_small.png");
+
+glfwSetWindowIcon(window, 2, images);
+@endcode
+
+The image data is 32-bit, little-endian, non-premultiplied RGBA, i.e. eight bits
+per channel with the red channel first.  The pixels are arranged canonically as
+sequential rows, starting from the top-left corner.
+
+To revert to the default window icon, pass in an empty image array.
+
+@code
+glfwSetWindowIcon(window, 0, NULL);
+@endcode
+
+
+@subsection window_monitor Window monitor
+
+Full screen windows are associated with a specific monitor.  You can get the
+handle for this monitor with @ref glfwGetWindowMonitor.
+
+@code
+GLFWmonitor* monitor = glfwGetWindowMonitor(window);
+@endcode
+
+This monitor handle is one of those returned by @ref glfwGetMonitors.
+
+For windowed mode windows, this function returns `NULL`.  This is how to tell
+full screen windows from windowed mode windows.
+
+You can move windows between monitors or between full screen and windowed mode
+with @ref glfwSetWindowMonitor.  When making a window full screen on the same or
+on a different monitor, specify the desired monitor, resolution and refresh
+rate.  The position arguments are ignored.
+
+@code
+const GLFWvidmode* mode = glfwGetVideoMode(monitor);
+
+glfwSetWindowMonitor(window, monitor, 0, 0, mode->width, mode->height, mode->refreshRate);
+@endcode
+
+When making the window windowed, specify the desired position and size.  The
+refresh rate argument is ignored.
+
+@code
+glfwSetWindowMonitor(window, NULL, xpos, ypos, width, height, 0);
+@endcode
+
+This restores any previous window settings such as whether it is decorated,
+floating, resizable, has size or aspect ratio limits, etc..  To restore a window
+that was originally windowed to its original size and position, save these
+before making it full screen and then pass them in as above.
+
+
+@subsection window_iconify Window iconification
+
+Windows can be iconified (i.e. minimized) with @ref glfwIconifyWindow.
+
+@code
+glfwIconifyWindow(window);
+@endcode
+
+When a full screen window is iconified, the original video mode of its monitor
+is restored until the user or application restores the window.
+
+Iconified windows can be restored with @ref glfwRestoreWindow.  This function
+also restores windows from maximization.
+
+@code
+glfwRestoreWindow(window);
+@endcode
+
+When a full screen window is restored, the desired video mode is restored to its
+monitor as well.
+
+If you wish to be notified when a window is iconified or restored, whether by
+the user, system or your own code, set an iconify callback.
+
+@code
+glfwSetWindowIconifyCallback(window, window_iconify_callback);
+@endcode
+
+The callback function receives changes in the iconification state of the window.
+
+@code
+void window_iconify_callback(GLFWwindow* window, int iconified)
+{
+    if (iconified)
+    {
+        // The window was iconified
+    }
+    else
+    {
+        // The window was restored
+    }
+}
+@endcode
+
+You can also get the current iconification state with @ref glfwGetWindowAttrib.
+
+@code
+int iconified = glfwGetWindowAttrib(window, GLFW_ICONIFIED);
+@endcode
+
+
+@subsection window_maximize Window maximization
+
+Windows can be maximized (i.e. zoomed) with @ref glfwMaximizeWindow.
+
+@code
+glfwMaximizeWindow(window);
+@endcode
+
+Full screen windows cannot be maximized and passing a full screen window to this
+function does nothing.
+
+Maximized windows can be restored with @ref glfwRestoreWindow.  This function
+also restores windows from iconification.
+
+@code
+glfwRestoreWindow(window);
+@endcode
+
+If you wish to be notified when a window is maximized or restored, whether by
+the user, system or your own code, set a maximize callback.
+
+@code
+glfwSetWindowMaximizeCallback(window, window_maximize_callback);
+@endcode
+
+The callback function receives changes in the maximization state of the window.
+
+@code
+void window_maximize_callback(GLFWwindow* window, int maximized)
+{
+    if (maximized)
+    {
+        // The window was maximized
+    }
+    else
+    {
+        // The window was restored
+    }
+}
+@endcode
+
+You can also get the current maximization state with @ref glfwGetWindowAttrib.
+
+@code
+int maximized = glfwGetWindowAttrib(window, GLFW_MAXIMIZED);
+@endcode
+
+By default, newly created windows are not maximized.  You can change this
+behavior by setting the [GLFW_MAXIMIZED](@ref GLFW_MAXIMIZED_hint) window hint
+before creating the window.
+
+@code
+glfwWindowHint(GLFW_MAXIMIZED, GLFW_TRUE);
+@endcode
+
+
+@subsection window_hide Window visibility
+
+Windowed mode windows can be hidden with @ref glfwHideWindow.
+
+@code
+glfwHideWindow(window);
+@endcode
+
+This makes the window completely invisible to the user, including removing it
+from the task bar, dock or window list.  Full screen windows cannot be hidden
+and calling @ref glfwHideWindow on a full screen window does nothing.
+
+Hidden windows can be shown with @ref glfwShowWindow.
+
+@code
+glfwShowWindow(window);
+@endcode
+
+By default, this function will also set the input focus to that window. Set
+the [GLFW_FOCUS_ON_SHOW](@ref GLFW_FOCUS_ON_SHOW_hint) window hint to change
+this behavior for all newly created windows, or change the behavior for an
+existing window with @ref glfwSetWindowAttrib.
+
+You can also get the current visibility state with @ref glfwGetWindowAttrib.
+
+@code
+int visible = glfwGetWindowAttrib(window, GLFW_VISIBLE);
+@endcode
+
+By default, newly created windows are visible.  You can change this behavior by
+setting the [GLFW_VISIBLE](@ref GLFW_VISIBLE_hint) window hint before creating
+the window.
+
+@code
+glfwWindowHint(GLFW_VISIBLE, GLFW_FALSE);
+@endcode
+
+Windows created hidden are completely invisible to the user until shown.  This
+can be useful if you need to set up your window further before showing it, for
+example moving it to a specific location.
+
+
+@subsection window_focus Window input focus
+
+Windows can be given input focus and brought to the front with @ref
+glfwFocusWindow.
+
+@code
+glfwFocusWindow(window);
+@endcode
+
+Keep in mind that it can be very disruptive to the user when a window is forced
+to the top.  For a less disruptive way of getting the user's attention, see
+[attention requests](@ref window_attention).
+
+If you wish to be notified when a window gains or loses input focus, whether by
+the user, system or your own code, set a focus callback.
+
+@code
+glfwSetWindowFocusCallback(window, window_focus_callback);
+@endcode
+
+The callback function receives changes in the input focus state of the window.
+
+@code
+void window_focus_callback(GLFWwindow* window, int focused)
+{
+    if (focused)
+    {
+        // The window gained input focus
+    }
+    else
+    {
+        // The window lost input focus
+    }
+}
+@endcode
+
+You can also get the current input focus state with @ref glfwGetWindowAttrib.
+
+@code
+int focused = glfwGetWindowAttrib(window, GLFW_FOCUSED);
+@endcode
+
+By default, newly created windows are given input focus.  You can change this
+behavior by setting the [GLFW_FOCUSED](@ref GLFW_FOCUSED_hint) window hint
+before creating the window.
+
+@code
+glfwWindowHint(GLFW_FOCUSED, GLFW_FALSE);
+@endcode
+
+
+@subsection window_attention Window attention request
+
+If you wish to notify the user of an event without interrupting, you can request
+attention with @ref glfwRequestWindowAttention.
+
+@code
+glfwRequestWindowAttention(window);
+@endcode
+
+The system will highlight the specified window, or on platforms where this is
+not supported, the application as a whole.  Once the user has given it
+attention, the system will automatically end the request.
+
+
+@subsection window_refresh Window damage and refresh
+
+If you wish to be notified when the contents of a window is damaged and needs
+to be refreshed, set a window refresh callback.
+
+@code
+glfwSetWindowRefreshCallback(m_handle, window_refresh_callback);
+@endcode
+
+The callback function is called when the contents of the window needs to be
+refreshed.
+
+@code
+void window_refresh_callback(GLFWwindow* window)
+{
+    draw_editor_ui(window);
+    glfwSwapBuffers(window);
+}
+@endcode
+
+@note On compositing window systems such as Aero, Compiz or Aqua, where the
+window contents are saved off-screen, this callback might only be called when
+the window or framebuffer is resized.
+
+
+@subsection window_transparency Window transparency
+
+GLFW supports two kinds of transparency for windows; framebuffer transparency
+and whole window transparency.  A single window may not use both methods.  The
+results of doing this are undefined.
+
+Both methods require the platform to support it and not every version of every
+platform GLFW supports does this, so there are mechanisms to check whether the
+window really is transparent.
+
+Window framebuffers can be made transparent on a per-pixel per-frame basis with
+the [GLFW_TRANSPARENT_FRAMEBUFFER](@ref GLFW_TRANSPARENT_FRAMEBUFFER_hint)
+window hint.
+
+@code
+glfwWindowHint(GLFW_TRANSPARENT_FRAMEBUFFER, GLFW_TRUE);
+@endcode
+
+If supported by the system, the window content area will be composited with the
+background using the framebuffer per-pixel alpha channel.  This requires desktop
+compositing to be enabled on the system.  It does not affect window decorations.
+
+You can check whether the window framebuffer was successfully made transparent
+with the
+[GLFW_TRANSPARENT_FRAMEBUFFER](@ref GLFW_TRANSPARENT_FRAMEBUFFER_attrib)
+window attribute.
+
+@code
+if (glfwGetWindowAttrib(window, GLFW_TRANSPARENT_FRAMEBUFFER))
+{
+    // window framebuffer is currently transparent
+}
+@endcode
+
+GLFW comes with an example that enabled framebuffer transparency called `gears`.
+
+The opacity of the whole window, including any decorations, can be set with @ref
+glfwSetWindowOpacity.
+
+@code
+glfwSetWindowOpacity(window, 0.5f);
+@endcode
+
+The opacity (or alpha) value is a positive finite number between zero and one,
+where 0 (zero) is fully transparent and 1 (one) is fully opaque.  The initial
+opacity value for newly created windows is 1.
+
+The current opacity of a window can be queried with @ref glfwGetWindowOpacity.
+
+@code
+float opacity = glfwGetWindowOpacity(window);
+@endcode
+
+If the system does not support whole window transparency, this function always
+returns one.
+
+GLFW comes with a test program that lets you control whole window transparency
+at run-time called `opacity`.
+
+
+@subsection window_attribs Window attributes
+
+Windows have a number of attributes that can be returned using @ref
+glfwGetWindowAttrib.  Some reflect state that may change as a result of user
+interaction, (e.g. whether it has input focus), while others reflect inherent
+properties of the window (e.g. what kind of border it has).  Some are related to
+the window and others to its OpenGL or OpenGL ES context.
+
+@code
+if (glfwGetWindowAttrib(window, GLFW_FOCUSED))
+{
+    // window has input focus
+}
+@endcode
+
+The [GLFW_DECORATED](@ref GLFW_DECORATED_attrib),
+[GLFW_RESIZABLE](@ref GLFW_RESIZABLE_attrib),
+[GLFW_FLOATING](@ref GLFW_FLOATING_attrib),
+[GLFW_AUTO_ICONIFY](@ref GLFW_AUTO_ICONIFY_attrib) and
+[GLFW_FOCUS_ON_SHOW](@ref GLFW_FOCUS_ON_SHOW_attrib) window attributes can be
+changed with @ref glfwSetWindowAttrib.
+
+@code
+glfwSetWindowAttrib(window, GLFW_RESIZABLE, GLFW_FALSE);
+@endcode
+
+
+

+glfwSetWindowAttrib.
+
+@anchor GLFW_AUTO_ICONIFY_attrib
+__GLFW_AUTO_ICONIFY__ indicates whether the specified full screen window is
+iconified on focus loss, a close widget, etc.  This can be set before creation
+with the [GLFW_AUTO_ICONIFY](@ref GLFW_AUTO_ICONIFY_hint) window hint or after
+with @ref glfwSetWindowAttrib.
+
+@anchor GLFW_FLOATING_attrib
+__GLFW_FLOATING__ indicates whether the specified window is floating, also
+called topmost or always-on-top.  This can be set before creation with the

+glfwSetWindowAttrib.
+
+@anchor GLFW_TRANSPARENT_FRAMEBUFFER_attrib
+__GLFW_TRANSPARENT_FRAMEBUFFER__ indicates whether the specified window has

+background using the window framebuffer alpha channel.  See @ref
+window_transparency for details.
+
+@anchor GLFW_FOCUS_ON_SHOW_attrib
+__GLFW_FOCUS_ON_SHOW__ specifies whether the window will be given input
+focus when @ref glfwShowWindow is called. This can be set before creation
+with the [GLFW_FOCUS_ON_SHOW](@ref GLFW_FOCUS_ON_SHOW_hint) window hint or
+after with @ref glfwSetWindowAttrib.
+
+@subsubsection window_attribs_ctx Context related attributes
+
+@anchor GLFW_CLIENT_API_attrib
+__GLFW_CLIENT_API__ indicates the client API provided by the window's context;
+either `GLFW_OPENGL_API`, `GLFW_OPENGL_ES_API` or `GLFW_NO_API`.
+
+@anchor GLFW_CONTEXT_CREATION_API_attrib
+__GLFW_CONTEXT_CREATION_API__ indicates the context creation API used to create
+the window's context; either `GLFW_NATIVE_CONTEXT_API`, `GLFW_EGL_CONTEXT_API`
+or `GLFW_OSMESA_CONTEXT_API`.
+
+@anchor GLFW_CONTEXT_VERSION_MAJOR_attrib
+@anchor GLFW_CONTEXT_VERSION_MINOR_attrib
+@anchor GLFW_CONTEXT_REVISION_attrib
+__GLFW_CONTEXT_VERSION_MAJOR__, __GLFW_CONTEXT_VERSION_MINOR__ and
+__GLFW_CONTEXT_REVISION__ indicate the client API version of the window's
+context.
+
+@note Do not confuse these attributes with `GLFW_VERSION_MAJOR`,
+`GLFW_VERSION_MINOR` and `GLFW_VERSION_REVISION` which provide the API version
+of the GLFW header.
+
+@anchor GLFW_OPENGL_FORWARD_COMPAT_attrib
+__GLFW_OPENGL_FORWARD_COMPAT__ is `GLFW_TRUE` if the window's context is an
+OpenGL forward-compatible one, or `GLFW_FALSE` otherwise.
+
+@anchor GLFW_OPENGL_DEBUG_CONTEXT_attrib
+__GLFW_OPENGL_DEBUG_CONTEXT__ is `GLFW_TRUE` if the window's context is an
+OpenGL debug context, or `GLFW_FALSE` otherwise.
+
+@anchor GLFW_OPENGL_PROFILE_attrib
+__GLFW_OPENGL_PROFILE__ indicates the OpenGL profile used by the context.  This
+is `GLFW_OPENGL_CORE_PROFILE` or `GLFW_OPENGL_COMPAT_PROFILE` if the context
+uses a known profile, or `GLFW_OPENGL_ANY_PROFILE` if the OpenGL profile is
+unknown or the context is an OpenGL ES context.  Note that the returned profile
+may not match the profile bits of the context flags, as GLFW will try other
+means of detecting the profile when no bits are set.
+
+@anchor GLFW_CONTEXT_RELEASE_BEHAVIOR_attrib
+__GLFW_CONTEXT_RELEASE_BEHAVIOR__ indicates the release used by the context.
+Possible values are one of `GLFW_ANY_RELEASE_BEHAVIOR`,
+`GLFW_RELEASE_BEHAVIOR_FLUSH` or `GLFW_RELEASE_BEHAVIOR_NONE`.  If the
+behavior is `GLFW_ANY_RELEASE_BEHAVIOR`, the default behavior of the context
+creation API will be used.  If the behavior is `GLFW_RELEASE_BEHAVIOR_FLUSH`,
+the pipeline will be flushed whenever the context is released from being the
+current one.  If the behavior is `GLFW_RELEASE_BEHAVIOR_NONE`, the pipeline will
+not be flushed on release.
+
+@anchor GLFW_CONTEXT_NO_ERROR_attrib
+__GLFW_CONTEXT_NO_ERROR__ indicates whether errors are generated by the context.
+Possible values are `GLFW_TRUE` and `GLFW_FALSE`.  If enabled, situations that
+would have generated errors instead cause undefined behavior.
+
+@anchor GLFW_CONTEXT_ROBUSTNESS_attrib
+__GLFW_CONTEXT_ROBUSTNESS__ indicates the robustness strategy used by the
+context.  This is `GLFW_LOSE_CONTEXT_ON_RESET` or `GLFW_NO_RESET_NOTIFICATION`
+if the window's context supports robustness, or `GLFW_NO_ROBUSTNESS` otherwise.
+
+
+@subsubsection window_attribs_fb Framebuffer related attributes
+
+GLFW does not expose attributes of the default framebuffer (i.e. the framebuffer
+attached to the window) as these can be queried directly with either OpenGL,
+OpenGL ES or Vulkan.
+
+If you are using version 3.0 or later of OpenGL or OpenGL ES, the
+`glGetFramebufferAttachmentParameteriv` function can be used to retrieve the
+number of bits for the red, green, blue, alpha, depth and stencil buffer
+channels.  Otherwise, the `glGetIntegerv` function can be used.
+
+The number of MSAA samples are always retrieved with `glGetIntegerv`.  For
+contexts supporting framebuffer objects, the number of samples of the currently
+bound framebuffer is returned.
+
+Attribute    | glGetIntegerv     | glGetFramebufferAttachmentParameteriv
+------------ | ----------------- | -------------------------------------
+Red bits     | `GL_RED_BITS`     | `GL_FRAMEBUFFER_ATTACHMENT_RED_SIZE`
+Green bits   | `GL_GREEN_BITS`   | `GL_FRAMEBUFFER_ATTACHMENT_GREEN_SIZE`
+Blue bits    | `GL_BLUE_BITS`    | `GL_FRAMEBUFFER_ATTACHMENT_BLUE_SIZE`
+Alpha bits   | `GL_ALPHA_BITS`   | `GL_FRAMEBUFFER_ATTACHMENT_ALPHA_SIZE`
+Depth bits   | `GL_DEPTH_BITS`   | `GL_FRAMEBUFFER_ATTACHMENT_DEPTH_SIZE`
+Stencil bits | `GL_STENCIL_BITS` | `GL_FRAMEBUFFER_ATTACHMENT_STENCIL_SIZE`
+MSAA samples | `GL_SAMPLES`      | _Not provided by this function_
+
+When calling `glGetFramebufferAttachmentParameteriv`, the red, green, blue and
+alpha sizes are queried from the `GL_BACK_LEFT`, while the depth and stencil
+sizes are queried from the `GL_DEPTH` and `GL_STENCIL` attachments,
+respectively.
+
+
+@section buffer_swap Buffer swapping
+
+GLFW windows are by default double buffered.  That means that you have two
+rendering buffers; a front buffer and a back buffer.  The front buffer is
+the one being displayed and the back buffer the one you render to.
+
+When the entire frame has been rendered, it is time to swap the back and the
+front buffers in order to display what has been rendered and begin rendering
+a new frame.  This is done with @ref glfwSwapBuffers.
+
+@code
+glfwSwapBuffers(window);
+@endcode
+
+Sometimes it can be useful to select when the buffer swap will occur.  With the
+function @ref glfwSwapInterval it is possible to select the minimum number of
+monitor refreshes the driver should wait from the time @ref glfwSwapBuffers was
+called before swapping the buffers:
+
+@code
+glfwSwapInterval(1);
+@endcode
+
+If the interval is zero, the swap will take place immediately when @ref
+glfwSwapBuffers is called without waiting for a refresh.  Otherwise at least
+interval retraces will pass between each buffer swap.  Using a swap interval of
+zero can be useful for benchmarking purposes, when it is not desirable to
+measure the time it takes to wait for the vertical retrace.  However, a swap
+interval of one lets you avoid tearing.
+
+Note that this may not work on all machines, as some drivers have
+user-controlled settings that override any swap interval the application
+requests.
+
+A context that supports either the `WGL_EXT_swap_control_tear` or the
+`GLX_EXT_swap_control_tear` extension also accepts _negative_ swap intervals,
+which allows the driver to swap immediately even if a frame arrives a little bit
+late.  This trades the risk of visible tears for greater framerate stability.
+You can check for these extensions with @ref glfwExtensionSupported.

+ * Title:   GLBoing
+ * Desc:    Tribute to Amiga Boing.
+ * Author:  Jim Brooks  <gfx@jimbrooks.org>
+ *          Original Amiga authors were R.J. Mical and Dale Luck.
+ *          GLFW conversion by Marcus Geelnard
+ * Notes:   - 360' = 2*PI [radian]
+ *
+ *          - Distances between objects are created by doing a relative
+ *            Z translations.
+ *
+ *          - Although OpenGL enticingly supports alpha-blending,
+ *            the shadow of the original Boing didn't affect the color
+ *            of the grid.
+ *
+ *          - [Marcus] Changed timing scheme from interval driven to frame-
+ *            time based animation steps (which results in much smoother
+ *            movement)
+ *
+ * History of Amiga Boing:
+ *
+ * Boing was demonstrated on the prototype Amiga (codenamed "Lorraine") in
+ * 1985. According to legend, it was written ad-hoc in one night by
+ * R. J. Mical and Dale Luck. Because the bouncing ball animation was so fast
+ * and smooth, attendees did not believe the Amiga prototype was really doing
+ * the rendering. Suspecting a trick, they began looking around the booth for
+ * a hidden computer or VCR.

+ *  [make it current](@ref context_current).  For information about the `share`
+ *  parameter, see @ref context_sharing.
+ *
+ *  The created window, framebuffer and context may differ from what you
+ *  requested, as not all parameters and hints are
+ *  [hard constraints](@ref window_hints_hard).  This includes the size of the
+ *  window, especially for full screen windows.  To query the actual attributes
+ *  of the created window, framebuffer and context, see @ref
+ *  glfwGetWindowAttrib, @ref glfwGetWindowSize and @ref glfwGetFramebufferSize.
+ *
+ *  To create a full screen window, you need to specify the monitor the window
+ *  will cover.  If no monitor is specified, the window will be windowed mode.
+ *  Unless you have a way for the user to choose a specific monitor, it is
+ *  recommended that you pick the primary monitor.  For more information on how
+ *  to query connected monitors, see @ref monitor_monitors.
+ *
+ *  For full screen windows, the specified size becomes the resolution of the
+ *  window's _desired video mode_.  As long as a full screen window is not
+ *  iconified, the supported video mode most closely matching the desired video
+ *  mode is set for the specified monitor.  For more information about full
+ *  screen windows, including the creation of so called _windowed full screen_
+ *  or _borderless full screen_ windows, see @ref window_windowed_full_screen.
+ *
+ *  Once you have created the window, you can switch it between windowed and
+ *  full screen mode with @ref glfwSetWindowMonitor.  This will not affect its
+ *  OpenGL or OpenGL ES context.
+ *
+ *  By default, newly created windows use the placement recommended by the
+ *  window system.  To create the window at a specific position, make it
+ *  initially invisible using the [GLFW_VISIBLE](@ref GLFW_VISIBLE_hint) window
+ *  hint, set its [position](@ref window_pos) and then [show](@ref window_hide)
+ *  it.
+ *
+ *  As long as at least one full screen window is not iconified, the screensaver
+ *  is prohibited from starting.
+ *
+ *  Window systems put limits on window sizes.  Very large or very small window
+ *  dimensions may be overridden by the window system on creation.  Check the
+ *  actual [size](@ref window_size) after creation.
+ *
+ *  The [swap interval](@ref buffer_swap) is not set during window creation and
+ *  the initial value may vary depending on driver settings and defaults.
+ *
+ *  @param[in] width The desired width, in screen coordinates, of the window.
+ *  This must be greater than zero.
+ *  @param[in] height The desired height, in screen coordinates, of the window.
+ *  This must be greater than zero.
+ *  @param[in] title The initial, UTF-8 encoded window title.
+ *  @param[in] monitor The monitor to use for full screen mode, or `NULL` for
+ *  windowed mode.
+ *  @param[in] share The window whose context to share resources with, or `NULL`
+ *  to not share resources.
+ *  @return The handle of the created window, or `NULL` if an
+ *  [error](@ref error_handling) occurred.

+ *  @remark @win32 Window creation will fail if the Microsoft GDI software
+ *  OpenGL implementation is the only one available.
+ *
+ *  @remark @win32 If the executable has an icon resource named `GLFW_ICON,` it
+ *  will be set as the initial icon for the window.  If no such icon is present,
+ *  the `IDI_APPLICATION` icon will be used instead.  To set a different icon,
+ *  see @ref glfwSetWindowIcon.
+ *
+ *  @remark @win32 The context to share resources with must not be current on
+ *  any other thread.
+ *
+ *  @remark @macos The OS only supports forward-compatible core profile contexts
+ *  for OpenGL versions 3.2 and later.  Before creating an OpenGL context of
+ *  version 3.2 or later you must set the
+ *  [GLFW_OPENGL_FORWARD_COMPAT](@ref GLFW_OPENGL_FORWARD_COMPAT_hint) and
+ *  [GLFW_OPENGL_PROFILE](@ref GLFW_OPENGL_PROFILE_hint) hints accordingly.
+ *  OpenGL 3.0 and 3.1 contexts are not supported at all on macOS.
+ *
+ *  @remark @macos The GLFW window has no icon, as it is not a document
+ *  window, but the dock icon will be the same as the application bundle's icon.
+ *  For more information on bundles, see the
+ *  [Bundle Programming Guide](https://developer.apple.com/library/mac/documentation/CoreFoundation/Conceptual/CFBundles/)
+ *  in the Mac Developer Library.
+ *
+ *  @remark @macos The first time a window is created the menu bar is created.
+ *  If GLFW finds a `MainMenu.nib` it is loaded and assumed to contain a menu
+ *  bar.  Otherwise a minimal menu bar is created manually with common commands
+ *  like Hide, Quit and About.  The About entry opens a minimal about dialog
+ *  with information from the application's bundle.  Menu bar creation can be
+ *  disabled entirely with the @ref GLFW_COCOA_MENUBAR init hint.
+ *
+ *  @remark @macos On OS X 10.10 and later the window frame will not be rendered
+ *  at full resolution on Retina displays unless the
+ *  [GLFW_COCOA_RETINA_FRAMEBUFFER](@ref GLFW_COCOA_RETINA_FRAMEBUFFER_hint)
+ *  hint is `GLFW_TRUE` and the `NSHighResolutionCapable` key is enabled in the
+ *  application bundle's `Info.plist`.  For more information, see
+ *  [High Resolution Guidelines for OS X](https://developer.apple.com/library/mac/documentation/GraphicsAnimation/Conceptual/HighResolutionOSX/Explained/Explained.html)
+ *  in the Mac Developer Library.  The GLFW test and example programs use
+ *  a custom `Info.plist` template for this, which can be found as
+ *  `CMake/MacOSXBundleInfo.plist.in` in the source tree.
+ *
+ *  @remark @macos When activating frame autosaving with
+ *  [GLFW_COCOA_FRAME_NAME](@ref GLFW_COCOA_FRAME_NAME_hint), the specified
+ *  window size and position may be overridden by previously saved values.
+ *
+ *  @remark @x11 Some window managers will not respect the placement of
+ *  initially hidden windows.
+ *
+ *  @remark @x11 Due to the asynchronous nature of X11, it may take a moment for
+ *  a window to reach its requested state.  This means you may not be able to
+ *  query the final size, position or other attributes directly after window
+ *  creation.
+ *
+ *  @remark @x11 The class part of the `WM_CLASS` window property will by
+ *  default be set to the window title passed to this function.  The instance
+ *  part will use the contents of the `RESOURCE_NAME` environment variable, if
+ *  present and not empty, or fall back to the window title.  Set the
+ *  [GLFW_X11_CLASS_NAME](@ref GLFW_X11_CLASS_NAME_hint) and
+ *  [GLFW_X11_INSTANCE_NAME](@ref GLFW_X11_INSTANCE_NAME_hint) window hints to
+ *  override this.
+ *
+ *  @remark @wayland Compositors should implement the xdg-decoration protocol
+ *  for GLFW to decorate the window properly.  If this protocol isn't
+ *  supported, or if the compositor prefers client-side decorations, a very
+ *  simple fallback frame will be drawn using the wp_viewporter protocol.  A
+ *  compositor can still emit close, maximize or fullscreen events, using for
+ *  instance a keybind mechanism.  If neither of these protocols is supported,
+ *  the window won't be decorated.
+ *
+ *  @remark @wayland A full screen window will not attempt to change the mode,

+ * Marcus: This code was originally written by Markus G. Kuhn.

+/*
+ * This module converts keysym values into the corresponding ISO 10646
+ * (UCS, Unicode) values.
+ *
+ * The array keysymtab[] contains pairs of X11 keysym values for graphical
+ * characters and the corresponding Unicode value. The function
+ * _glfwKeySym2Unicode() maps a keysym onto a Unicode value using a binary
+ * search, therefore keysymtab[] must remain SORTED by keysym value.
+ *
+ * We allow to represent any UCS character in the range U-00000000 to
+ * U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
+ * This admittedly does not cover the entire 31-bit space of UCS, but
+ * it does cover all of the characters up to U-10FFFF, which can be
+ * represented by UTF-16, and more, and it is very unlikely that higher
+ * UCS codes will ever be assigned by ISO. So to get Unicode character
+ * U+ABCD you can directly use keysym 0x0100abcd.
