305ef3215d Modify how the four output reverb points are calculated 
For HRTF and B-Format output, the points no longer move but instead scale based
on the desired panning direction.

d315ca4139 Try to map reverb outputs directly to output channels 
HRTF and B-Format output still need to use virtual panning directions, but the
reverb works better when it outputs directly to an output channel. Ambient and
directional panning is used to properly mask and attenuate each output channel.

Note that currently the "direct panning" output is quieter than it should be.
Work is underway to attenuate the early reflections and late reverb better.

9ce2b8f9a7 Always update all reverb properties 
The EAX-only effect properties will be set to compatible defaults when standard
reverb is set, and the EAX-only effects will be skipped during sample
processing.

a77387b549 Avoid taking the square-root of the ambient gain 
Although it is more correct for preserving the apparent volume, the ambisonics-
based panning does not work on the same power scale, making it louder by
comparison.

48aa1e10d6 Use the high-shelf filter in place of low-pass 
They effectively both work to lower (or raise) high frequencies. However, the
high-shelf performs better when gain=1.
