fixed numerous shadowmapping bugs. actually seems to work now. appears to draw more lights than is actually needed, however. changed how keyboard focus works. can now have menu+console open at once, although you probably need shift+escape to get at it. fixed a few issues with nexuiz compat. there are *still* other issues. greatly refactored cd playback code. cd driver code is now a backend only and does not provide its own commands. track remapping accepts named faketracks. worked around missing notifications in vista+, so looping will now work. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4491 fc73d0e0-1445-4013-8a0c-d673dee63da5
