/**
The Fl_Slider widget contains a sliding knob inside a box. It is
often used as a scrollbar. Moving the box all the way to the
top/left sets it to the minimum(), and to the bottom/right to the
maximum(). The minimum() may be greater than the maximum() to
reverse the slider direction.
Use void Fl_Widget::type(int) to set how the slider is drawn,
which can be one of the following:
\li FL_VERTICAL - Draws a vertical slider (this is the default).
\li FL_HORIZONTAL - Draws a horizontal slider.
\li FL_VERT_FILL_SLIDER - Draws a filled vertical slider,
useful as a progress or value meter.
\li FL_HOR_FILL_SLIDER - Draws a filled horizontal slider,
useful as a progress or value meter.
\li FL_VERT_NICE_SLIDER - Draws a vertical slider with a nice
looking control knob.
\li FL_HOR_NICE_SLIDER - Draws a horizontal slider with a
nice looking control knob.
