+/**
+ The Fl_Slider widget contains a sliding knob inside a box. It if
+ 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.
