28 * 4 12/02/98 5:47p Dave
29 * Put in interface xstr code. Converted barracks screen to new format.
31 * 3 10/13/98 9:29a Dave
32 * Started neatening up freespace.h. Many variables renamed and
33 * reorganized. Added AlphaColors.[h,cpp]

38 * 1 10/07/98 10:51a Dave
40 * 9 3/10/98 4:19p John
41 * Cleaned up graphics lib. Took out most unused gr functions. Made D3D
42 * & Glide have popups and print screen. Took out all >8bpp software
43 * support. Made Fred zbuffer. Made zbuffer allocate dynamically to
44 * support Fred. Made zbuffering key off of functions rather than one
47 * 8 2/03/98 4:21p Hoffoss
48 * Made UI controls draw white text when disabled.
50 * 7 1/14/98 6:44p Hoffoss
51 * Massive changes to UI code. A lot cleaner and better now. Did all
52 * this to get the new UI_DOT_SLIDER to work properly, which the old code
53 * wasn't flexible enough to handle.
55 * 6 6/12/97 12:39p John
56 * made ui use freespace colors
58 * 5 6/11/97 1:13p John
59 * Started fixing all the text colors in the game.
61 * 4 5/26/97 10:26a Lawrance
