10 * $Logfile: /Freespace2/code/Graphics/Font.h $
15 * header file for font stuff
18 * Revision 1.2 2002/06/09 04:41:13 relnev
19 * added copyright header
21 * Revision 1.1.1.1 2002/05/03 03:28:12 root
25 * 4 7/09/99 10:32p Dave
26 * Command brief and red alert screens.
28 * 3 10/13/98 9:28a Dave
29 * Started neatening up freespace.h. Many variables renamed and
30 * reorganized. Added AlphaColors.[h,cpp]
32 * 2 10/07/98 10:52a Dave
35 * 1 10/07/98 10:49a Dave
37 * 14 5/25/98 10:32a John
38 * Took out redundant code for font bitmap offsets that converted to a
39 * float, then later on converted back to an integer. Quite unnecessary.
41 * 13 3/25/98 8:07p John
42 * Restructured software rendering into two modules; One for windowed
43 * debug mode and one for DirectX fullscreen.
45 * 12 3/10/98 4:18p John
46 * Cleaned up graphics lib. Took out most unused gr functions. Made D3D
47 * & Glide have popups and print screen. Took out all >8bpp software
48 * support. Made Fred zbuffer. Made zbuffer allocate dynamically to
49 * support Fred. Made zbuffering key off of functions rather than one
52 * 11 3/09/98 6:06p John
53 * Restructured font stuff to avoid duplicate code in Direct3D and Glide.
54 * Restructured Glide to avoid redundent state setting.
56 * 10 2/19/98 9:04a John
57 * Fixed fonts with glide
59 * 9 2/17/98 7:27p John
60 * Got fonts and texturing working in Direct3D
62 * 8 11/30/97 12:18p John
63 * added more 24 & 32-bpp primitives
65 * 7 11/06/97 5:42p Hoffoss
66 * Added support for fixed size timstamp rendering.
68 * 6 11/03/97 10:59a John
69 * added support for more than one font.
71 * 5 10/24/97 12:13p Hoffoss
72 * Added gr_force_fit_string().
74 * 4 10/09/97 5:23p John
75 * Added support for more 16-bpp functions
77 * 3 6/05/97 4:53p John
78 * First rev of new antialiased font stuff.
80 * 2 4/22/97 10:33a John
81 * fixed the 2d resource leaks that Alan found.
83 * 1 3/31/97 9:42a Allender
