Added win7 recently opened links, so rightclicking pinned icons gives recent servers. Perhaps not the best implementation (lol) but yay, only a little bit of horrible COM crap. Hacked about with the scripted particle system. Classic is now the default set, but the scripted system is still active and can be used by mods or whatever if they wish. Interpolation changes: should feel better on non-fte QW servers now. Not sure about other server types. Added svc_setanglesdelta. Fixed vwep+skins. git-svn-id: https://svn.code.sf.net/p/fteqw/code/branches/wip@3682 fc73d0e0-1445-4013-8a0c-d673dee63da5

/*
|
|
This is based on Jogi's OpenAL support.
|
|
Much of it is stripped, to try and get it clean/compliant.
|
|
|
|
Missing features:
|
|
FIXME: does not kill old sounds on replaced sound channels (quake compliance).
|
|
FIXME: no static/ambient sounds (quake compliance).
|
|
FIXME: does not support streaming audio from voice/videos (voice/q2/q3 compliance).
|
|
If the above ar implemented, it can be the default device.
|
|
FIXME: listener velocity calculations (currently ugly).
|
|
FIXME: does not track entity velocities, so no dopler (awkward, quake move playing sounds at all).
|
|
FIXME: no eax (underwater).
|
|
FIXME: a capture device would be useful (voice chat).
