/*

* Interface to piggy functions.
|
|
*
|
|
* Old Log:
|
|
* Revision 1.1 1995/05/16 16:01:04 allender
|
|
* Initial revision
|
|
*
|
|
* Revision 2.0 1995/02/27 11:31:21 john
|
|
* New version 2.0, which has no anonymous unions, builds with
|
|
* Watcom 10.0, and doesn't require parsing BITMAPS.TBL.
|
|
*
|
|
* Revision 1.10 1995/02/03 17:08:29 john
|
|
* Changed sound stuff to allow low memory usage.
|
|
* Also, changed so that Sounds isn't an array of digi_sounds, it
|
|
* is a ubyte pointing into GameSounds, this way the digi.c code that
|
|
* locks sounds won't accidentally unlock a sound that is already playing, but
|
|
* since it's Sounds[soundno] is different, it would erroneously be unlocked.
|
|
*
|
|
* Revision 1.9 1995/01/24 14:33:49 john
|
|
* *** empty log message ***
|
|
*
|
|
* Revision 1.8 1995/01/24 14:32:35 john
|
|
* Took out paging in code.
|
|
*
|
|
* Revision 1.7 1995/01/23 12:30:17 john
|
|
* Made debug code that mprintf what bitmap gets paged in.
|
|
*
|
|
* Revision 1.6 1995/01/17 14:11:37 john
|
|
* Added function that is called after level loaded.
|
|
*
|
|
* Revision 1.5 1995/01/14 19:16:58 john
|
|
* First version of new bitmap paging code.
|
|
*
|
|
* Revision 1.4 1994/10/27 18:51:57 john
|
|
* Added -piglet option that only loads needed textures for a
|
|
* mine. Only saved ~1MB, and code still doesn't free textures
|
|
* before you load a new mine.
|
|
*
|
|
* Revision 1.3 1994/06/08 14:20:47 john
|
|
* Made piggy dump before going into game.
|
|
*
|
|
* Revision 1.2 1994/05/06 13:02:40 john
|
|
* Added piggy stuff; worked on supertransparency
|
|
*
|
|
* Revision 1.1 1994/05/06 11:47:46 john
