Reimplement panning using lookup tables, based on a patch by Christian Borss
...
This allows speaker positions to be specified by discrete angles around the
listener, providing more flexibility and configurability in placement.
Additional patches to take advantage of this are forthcoming.

Add initial AL_EXTX_buffer_sub_data support
...
Note that this is an in-development extension, as noted by the EXTX moniker
instead of EXT. It's behavior is subject to change, and the extension string
will be removed (replaced with the official string once it's finalized).
Developers are discouraged from using this in production code, though feel
free to play around with it.

Implement an alternative low-pass filter
...
This method samples from the buffer so that it gets a time-correct 5khz stream,
which is subtracted from the original sample and has the high-frequency gain
applied, then added back.
A better method may be to average all the samples from the current one to the
one freq/5000 away, instead of bilinear filtering the two nearest freq/5000
apart. Processing cost will need to determine its viability
