 * $Revision: 2.0 $
 * $Author: john $
 * $Date: 1995/02/27 11:31:21 $
 * 
 * Interface to piggy functions.
 * 
 * $Log: piggy.h $
 * 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
 * Initial revision
