Add FL_BACKGROUND_COLOR, FL_BACKGROUND2_COLOR, and FL_FOREGROUND_COLOR, and use them instead of FL_GRAY, FL_WHITE, and FL_BLACK, respectively. (FL_GRAY defined to FL_BACKGROUND_COLOR for back-compatibility) Add fl_rgb_color(uchar g) inline method to map 8-bit grayscale to 24-bit RGB color. Doco updates for all of this... git-svn-id: file:///fltk/svn/fltk/branches/branch-1.1@2072 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
