/**
The Fl_Double_Window provides a double-buffered window.
If possible this will use the X double buffering extension (Xdbe). If
not, it will draw the window data into an off-screen pixmap, and then
copy it to the on-screen window.
<P>It is highly recommended that you put the following code before the
first show() of <I>any</I> window in your program: </P>
\code
Fl::visual(FL_DOUBLE|FL_INDEX)
\endcode
This makes sure you can use Xdbe on servers where double buffering
does not exist for every visual.
