- Added rotation 90° angles only) and mirroring to the Multipatch texture
composition code.
- Fixed: The game crashed when a level was ended while a player was morphed
by a powerup.
- Fixed: A_VileAttack positioned the fire on the wrong side of the target.
- Reorganized the HackHack code so that the image creation was moved into
MakeTexture. This was necessary because Unload deleted the pixel data

- Fixed: A few calls to P_SpawnPlayerMissile passed 0 as angle
April 13, 2008 (Changes by Graf Zahl)
- Fixed a few bufs in the parser for composite textures.
- Fixed a few bugs in the parser for composite textures.
- Changed: When loading Zips all patches in the patches/ directory should
be loaded, not only those used by a texture in TEXTUREx.
- Disabled timidity_mastervolume for the internal Timidity again because
