/*

This is based on Jogi's OpenAL support.
|
|
Much of it is stripped, to try and get it clean/compliant.
|
|
|
|
Missing features:
|
|
FIXME: listener velocity calculations (currently ugly).
|
|
FIXME: does not track entity velocities, so no dopler (awkward, quake doesn't move playing sounds at all).
|
|
FIXME: no eax / efx (underwater reverb etc).
|
|
FIXME: a capture device would be useful (voice chat).
