Change openal usage to try to be more conformant to spec (should only be an issue for less mature openal implementations though). Added a developer warning if fog is oversaturated. Fix crash when loading a game with an animated texture in view... yes, weird. Support big-endian ktx files. Added some wrath builtins. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5588 fc73d0e0-1445-4013-8a0c-d673dee63da5
