 * 9     3/10/98 4:19p John
 * Cleaned up graphics lib.  Took out most unused gr functions.   Made D3D
 * & Glide have popups and print screen.  Took out all >8bpp software
 * support.  Made Fred zbuffer.  Made zbuffer allocate dynamically to
 * support Fred.  Made zbuffering key off of functions rather than one
 * global variable.

 * Made UI controls draw white text when disabled.

 * 7     1/14/98 6:44p Hoffoss
 * Massive changes to UI code.  A lot cleaner and better now.  Did all
 * this to get the new UI_DOT_SLIDER to work properly, which the old code
 * wasn't flexible enough to handle.
