- Fixed: Actor-less sounds that aren't played on CHAN_AUTO should still be
subject to channel overriding.
- Re-added priority selection based on sound usage.
- Reduced the number of virtual channels to match the number of real
channels.
- Added customizable rolloff, including Doom's standard linear gain rolloff.
SNDINFO commands are:
$rolloff <sound> <min distance> <max distance> -- linear gain (like Doom)
$rolloff <sound> linear <min distance> <max distance> -- linear volume
$rolloff <sound> log <min distance> <rolloff factor> -- logarithmic
$rolloff <sound> custom <min distance> <max distance> -- use SNDCURVE lump
Anything closer than min distance is full volume and anything further than
max distance is inaudible. Logarithmic rolloff does not have a maximum
distance; it has a scalar that controls how quickly the volume drops off
instead.

|

- Disabled scrolling of 3DMIDTEX textures. Due to the special needs this
|

cannot work properly.
