Downmixing should no longer be necessary, unless someone actually tries
to emit up to 64 channels, while we support only 32 channels, but really
only 18 channels. Also read the channel layout field from the decoder,
so that the speaker layout will propagate from the files to the player.

The equalizer needs to apply its presets to the new settings variables
every time the preset changes, even when it happens with no dialog open.

vDSP functions expect their input and output pointers to be aligned to
an even four values. Correct this by aligning all pointers. The
allocated buffers used for one parameter should already be aligned
somewhat, but align the incremented positions used on some of them so
that the vDSP functions don't misbehave. Also align the volume scaler
input by doing scalar math until the pointer is aligned prior to calling
vDSP_vsmul. Also, change 16-bit and 32-bit scale to use vsdiv instead of
vsmul with a really small number already divided into one.
Fixes the test vectors that were sent in extrapolating incorrectly due
to their final blocks having uneven sample counts, resulting in
unaligned pointers.

A bad sample scanner and cleaner will point out in the log whenever a
bad sample, such as infinity, or Not a Number, or even huge values over
±2.0, in case some piece of code, or a decoder, or even a bad file, has
taken over the output.

The original didn't really handle backwards versus forwards differently,
as far as the predictor coefficients should have been, as they probably
should have been reversed for a different direction window.
This didn't fix my problem, though, but did possibly expose something
else to mess with.

In the rare event that we're somehow playing decimated DSD at full
sample rate instead of resampling, only the start needs to be skipped,
and the end needs the input to the decimator padded to flush it, but
nothing needs to be truncated from the end of the output in that case.
Still, mostly pointless, since next to nobody will be outputting 384 kHz
from their Macs, in any case, much less unprocessed DSD.

We should be extrapolating right over top of the DSD decimator latency,
rather than in front of it. Yeah, that'll do.

Reduce the virtual resolution to match the actual resolution, and set
the analyzere frequency to Nyquist of the audio input, as it seems to
behave as if the entire range of the input FFT bands are up to the
specified frequency, rather than half of it. Otherwise, we lose half of
the frequency range provided by the input data.
