 * File Description:
 *    CColorButton: A widget that carries a CGlColor (RGB value) as state.
 *   When clicked it presents a color chooser to change its state.
 *   It displays its color state in a patch or in text format or both.
 *   Its color state is not the same as its FLTK color(), nor is the text
 *   description of the color the FLTK label.
