  19  * Revision 1.26  2006-12-13 04:44:17  kkurbjun
  20  * Dehacked and BEX support for Doom - currently only supports a DEHACKED file in a WAD (not as a standalone file yet).
  21  *
  22  * Revision 1.25  2006-10-26 13:38:04  barrywardell
  23  * Allow the Sansa e200 UI simulator to be built. Thanks to Andre Smith for the nice image of the Sansa. Lots more to be done including testing and tweaking the keymaps and modifying the plugins for the Sansa's 176x220 LCD.
  24  *
  25  * Revision 1.24  2006-09-05 00:23:06  barrywardell
  26  * Fix not being able to exit Doom on the H10.
  27  *
  28  * Revision 1.23  2006-08-10 18:34:43  amiconn
  29  * Correct calculation of necessary buffer size to give maximum number of shades on iPod Mini.
  30  *
  31  * Revision 1.22  2006-08-07 02:44:18  amiconn
  32  * Use striped buffering for grayscale targets to make the buffer fit on iPod g3/g4. Also slightly faster (at least on H1x0) with the buffer in IRAM.
  33  *
  34  * Revision 1.21  2006-08-07 01:57:29  amiconn
  35  * Fix red iPod g3 build.
  36  *
  37  * Revision 1.20  2006-08-07 01:46:41  amiconn
  38  * Grayscale library ported to the grayscale iPods, first version. Added C reference versions of gray_update_rect() for both horizontal and vertical pixel packing. gray_update_rect() and gray_ub_gray_bitmap_part() not yet assembler optimised. Grayscale screendump doesn't work yet. * Fixed button assignments for iPod in grayscale.c
  39  *
  40  * Revision 1.19  2006-08-03 20:17:22  bagder
  41  * Barry Wardell's keymappings for H10
  42  *
  43  * Revision 1.18  2006-08-02 00:21:59  amiconn
  44  * Grayscale library: LCD linearisation and gamma correction.
  45  *
  46  * Revision 1.17  2006-04-22 03:48:15  kkurbjun
  47  * Better video update, add options to startup menu, change default screensize
  48  *
  49  * Revision 1.16  2006-04-20 19:39:56  kkurbjun
  50  * Optimizations for doom: coldfire asm drawspan routine = not much, fixed point multiply changes = not much, H300 asm lcd update = some, IRAM sound updates and simplifications = more
  51  *
  52  * Revision 1.15  2006-04-16 23:14:04  kkurbjun
  53  * Fix run so that it stays enabled across level loads.  Removed some unused code and added some back in for hopeful future use.
  54  *
  55  * Revision 1.14  2006-04-15 22:08:36  kkurbjun
  56  * Slight code cleanups, fixed sound parameter - now it saves.  Old configurations will be reset.
  57  *
  58  * Revision 1.13  2006-04-06 21:31:49  kkurbjun
  59  * Scaling code fixed by clamping down the width to a max of SCREENWIDTH.  Removed some #ifdefs for glprboom
  60  *
  61  * Revision 1.12  2006-04-05 06:37:37  kkurbjun
  62  * Fix finale text and try and prevent some data corruption due to the scaling code.  Also allows the non-standard GP32 mods to work with some bounds checking.  More comments are in v_video.c
  63  *
  64  * Revision 1.11  2006-04-04 19:39:31  amiconn
  65  * Doom on H1x0: Don't waste memory, the grayscale lib doesn't need that much, but properly tell the lib how much memory it may use.
  66  *
  67  * Revision 1.10  2006-04-04 12:00:53  dave
  68  * iPod: Make the hold switch bring up the in-game menu.
  69  *
  70  * Revision 1.9  2006-04-03 20:03:02  kkurbjun
  71  * Updates doom menu w/ new graphics, now requires rockdoom.wad: http://alamode.mines.edu/~kkurbjun/rockdoom.wad
  72  *
  73  * Revision 1.8  2006-04-03 17:11:42  kkurbjun
  74  * Finishing touches
  75  *
  76  * Revision 1.7  2006-04-03 16:30:12  kkurbjun
  77  * Fix #if
  78  *
  79  * Revision 1.5  2006-04-03 08:51:08  bger
  80  * Patch #4864 by Jonathan Gordon: text editor plugin, with some changes by me.
  81  * Also correct a var clash between the rockbox's gui api and doom plugin
  82  *
  83  * Revision 1.4  2006-04-02 20:45:24  kkurbjun
  84  * Properly ifdef H300 video code, fix commented line handling rockbox volume
  85  *
  86  * Revision 1.3  2006-04-02 01:52:44  kkurbjun
  87  * Update adds prboom's high resolution support, also makes the scaling for
  88  * platforms w/ resolution less then 320x200 much nicer.  IDoom's lookup table
  89  * code has been removed.  Also fixed a pallete bug.  Some graphic errors are
  90  * present in menu and status bar.  Also updates some headers and output
  91  * formatting.
  92  *
  93  * Revision 1.2  2006-03-28 17:20:49  christian
  94  * added good (tm) button mappings for x5, and added ifdef for HAS_BUTTON_HOLD
  95  *
  96  * Revision 1.1  2006-03-28 15:44:01  dave
