23cae7783d Properly scale the first HRTF pass-through coefficient 
Coefficients are scaled by 32767. For pass-through, this is attenuated by
sqrt(0.5) to maintain a consistent perceived volume.

15d7ed2f0d Cleanup some HRTF code 
Use loops instead of duplicating code, rewrite some lines to be clearer.

f4cdecebcf Add a source radius property that determines the directionality of a sound 
At 0 distance from the listener, the sound is omni-directional. As the source
and listener become 'radius' units apart, the sound becomes more directional.

With HRTF, an omni-directional sound is handled using 0-delay, pass-through
filter coefficients, which is blended with the real delay and coefficients as
needed to become more directional.

389a2f7b4b Store and use an ALbuffer for samples in an ALfontsound 
The fontsound still maintains its own start, end, and loop offsets, so that the
same buffer may be shared between multiple/all fontsounds. Ideally a single
buffer should be used for all fontsounds to avoid memory fragmentation and help
CPU caching, although higher quality soundfonts may need more memory than a
single buffer can hold.

fc0be88c0f Add SSE2 and SSE4.1 linear resamplers 
Currently the only way SSE 4.1 is detected is by using __get_cpuid, i.e. with
GCC. Windows' IsProcessorFeaturePresent does not report SSE4.1 capabilities.
