Minor modifications to the menus:

Minor modifications to the menus:

 * Updated an old "TODO BEFORE STABLE" comment.

 * Expanded a comment re. some #define macros.

 * Made colors and font choice system dependant.  The UNIX freeglut
   menus look more like UNIX GLUT menus, now.  (This is PURELY a
   cosmetic change.  But it achieves better compatibility visually.)
