This allows us to avoid copying samples when no filtering is needed. Doing the
same for resampling would require another temporary buffer in the device.

They are still there for auxiliary sends. However, they should go away soon
enough too, and then we won't have to mess around with calculating extra
"predictive" samples in the mixer.

Step mixing gains per-sample for non-HRTF mixing
...
This fades the dry mixing gains using a logarithmic curve, which should produce
a smoother transition than a linear one. It functions similarly to a linear
fade except that
step = (target - current) / numsteps;
...
gain += step;
becomes
step = powf(target / current, 1.0f / numsteps);
...
gain *= step;
where 'target' and 'current' are clamped to a lower bound that is greater than
0 (which makes no sense on a logarithmic scale).
Consequently, the non-HRTF direct mixers do not do not feed into the click
removal and pending click buffers, as this per-sample fading would do an
adequate job of stopping clicks and pops caused by extreme gain changes. These
buffers should be removed shortly.

Deinterlace audio when loading it into the stack.

It may be better to deinterlace it on load into the buffer, though I don't
imagine this will affect much. It could be nice for consistency's sake, though
it would also complicate things if we ever want to support direct access to
buffer data.
