Find shortest textures like Doom	Compat_ShortTex	1	In Doom, AASHITTY in Doom II or AASTINKY in Doom was created to fill in the place of texture index 0, normally treated by the Doom engine as no texture at all. When this is enabled, the "raise platform by lower texture" line special and MAP07 floor raise considers AASHITTY or AASTINKY as a valid texture and uses it's height when raising a platform. If disabled, these textures aren't considered valid and are ignored.

Disable taunts	Compat_DisableTaunts	1048576	Prevents players from using the "taunt" command.
