15 * Tool for interactively kerning fonts
18 * Revision 1.4 2006/04/26 19:38:36 taylor
19 * fix some minor fonttool compile errors
21 * Revision 1.3 2003/01/30 20:03:48 relnev
22 * various files ported needed for fonttool. There is a bug where on exit it segfaults in SDL_GL_SwapBuffers, I'm probably missing something (don't know what) but it works fine otherwise (Taylor Richards)
24 * Revision 1.2 2002/06/09 04:41:16 relnev
25 * added copyright header
27 * Revision 1.1.1.1 2002/05/03 03:28:08 root
31 * 6 5/19/99 4:07p Dave
32 * Moved versioning code into a nice isolated common place. Fixed up
33 * updating code on the pxo screen. Fixed several stub problems.
35 * 5 12/18/98 1:14a Dave
36 * Rough 1024x768 support for Direct3D. Proper detection and usage through
39 * 4 12/02/98 9:58a Dave
40 * Got fonttool working under glide/direct3d.
42 * 3 11/30/98 1:09p Dave
44 * 2 10/24/98 5:15p Dave
46 * 1 10/24/98 4:58p Dave
48 * 14 5/06/98 5:30p John
49 * Removed unused cfilearchiver. Removed/replaced some unused/little used
50 * graphics functions, namely gradient_h and _v and pixel_sp. Put in new
51 * DirectX header files and libs that fixed the Direct3D alpha blending
54 * 13 4/13/98 10:11a John
55 * Made timer functions thread safe. Made timer_init be called in all
58 * 12 3/10/98 4:18p John
59 * Cleaned up graphics lib. Took out most unused gr functions. Made D3D
60 * & Glide have popups and print screen. Took out all >8bpp software
61 * support. Made Fred zbuffer. Made zbuffer allocate dynamically to
62 * support Fred. Made zbuffering key off of functions rather than one
65 * 11 3/05/98 11:15p Hoffoss
66 * Changed non-game key checking to use game_check_key() instead of
69 * 10 10/30/97 4:56p John
70 * Fixed up font stuff to build. Fixed bug where it didn't show the last
71 * 3 characters in kerning table.
73 * 9 9/03/97 4:32p John
74 * changed bmpman to only accept ani and pcx's. made passing .pcx or .ani
75 * to bm_load functions not needed. Made bmpman keep track of palettes
76 * for bitmaps not mapped into game palettes.
78 * 8 6/06/97 6:47p John
81 * 7 6/06/97 4:41p John
82 * Fixed alpha colors to be smoothly integrated into gr_set_color_fast
85 * 6 6/06/97 11:10a John
86 * made scrolling kern pair box.
88 * 5 6/06/97 9:21a John
89 * added some kerning pairs
91 * 4 6/06/97 9:18a John
92 * Added capital hamburger.
94 * 3 6/05/97 5:00p John
97 * 2 6/05/97 4:53p John
98 * First rev of new antialiased font stuff.
100 * 1 6/02/97 4:04p John
