will attempt to load doom3 maps. _gl_fog 1 and friends can be used to activate fog, still needs tweeks for use, not a final feature at all. added gl_screenangle which rotates the screen, including hud. seems to be some nvidia driver issue. may need end-tasking after video shuts down (including from-fullscreen vid_restarts). double-frees on glsl shaders is now supposedly fixed. git-svn-id: https://svn.code.sf.net/p/fteqw/code/branches/wip@3735 fc73d0e0-1445-4013-8a0c-d673dee63da5
