/*
openal.c TODO:
1. AL_PITCH code does not work.
OpenAL alf_tpitch is currently broken. (Doesn't work with LOOPING, etc.)
Maps like Last Stand use it for (some rather odd) ambient sounds.
1. AL_PITCH seems to work, but laststand is still a bit weird.
2. Panning somewhat works now. Need someone to verify.
3. There is no EAX/Reverb. But there's probably not much I can do...
4. Restarting sound system may or may not work.
5. Doppler (if it was originally used) isn't currently used.
Probably also broken in OpenAL (see 1).
6. Better Error Handling (device not avail, etc).
