Looks good, although I would shorten the function name, maybe
fl_rgb_from_color, fl_color_to_rgb, or ... ?
And, while we're at it, Edzard's proposal could be added as well,
Fl::background(Fl_Color);
Fl::background2(Fl_Color);
Should be simple, just two overloaded methods calling the existing
functions.
