August 17, 2006 (Changes by Graf Zahl)
- Added a check to the map loader to check whether the map label
is in the same WAD as the following lump.
- Did some minor reorganization of code in r_data.cpp (mostly to make
handling of textures easier in GZDoom.)
- Did some preparations to allow loading folders on the HD into the lump
directory.
- Took MF2_WINDTHRUST off AMorphedMonster. This is something that should not
be a default setting.
- Moved a_artiegg.cpp to g_shared and renamed it to a_morph.cpp to better reflect
