7 * header file for font stuff
10 * Revision 1.1 2002/05/03 03:28:12 root
14 * 4 7/09/99 10:32p Dave
15 * Command brief and red alert screens.
17 * 3 10/13/98 9:28a Dave
18 * Started neatening up freespace.h. Many variables renamed and
19 * reorganized. Added AlphaColors.[h,cpp]
21 * 2 10/07/98 10:52a Dave
24 * 1 10/07/98 10:49a Dave
26 * 14 5/25/98 10:32a John
27 * Took out redundant code for font bitmap offsets that converted to a
28 * float, then later on converted back to an integer. Quite unnecessary.
30 * 13 3/25/98 8:07p John
31 * Restructured software rendering into two modules; One for windowed
32 * debug mode and one for DirectX fullscreen.
34 * 12 3/10/98 4:18p John
35 * Cleaned up graphics lib. Took out most unused gr functions. Made D3D
36 * & Glide have popups and print screen. Took out all >8bpp software
37 * support. Made Fred zbuffer. Made zbuffer allocate dynamically to
38 * support Fred. Made zbuffering key off of functions rather than one
41 * 11 3/09/98 6:06p John
42 * Restructured font stuff to avoid duplicate code in Direct3D and Glide.
43 * Restructured Glide to avoid redundent state setting.
45 * 10 2/19/98 9:04a John
46 * Fixed fonts with glide
48 * 9 2/17/98 7:27p John
49 * Got fonts and texturing working in Direct3D
51 * 8 11/30/97 12:18p John
52 * added more 24 & 32-bpp primitives
54 * 7 11/06/97 5:42p Hoffoss
55 * Added support for fixed size timstamp rendering.
57 * 6 11/03/97 10:59a John
58 * added support for more than one font.
60 * 5 10/24/97 12:13p Hoffoss
61 * Added gr_force_fit_string().
63 * 4 10/09/97 5:23p John
64 * Added support for more 16-bpp functions
66 * 3 6/05/97 4:53p John
67 * First rev of new antialiased font stuff.
69 * 2 4/22/97 10:33a John
70 * fixed the 2d resource leaks that Alan found.
72 * 1 3/31/97 9:42a Allender
