I'm actually not sure about this last bit. I originally considered the
samples "valid", but it looks like parts of the samples I was looking at
are synthetic coefficient blocks, for which no defined output exists. So I
may (subsets of) some of these patches in the future if I have time to
analyze exactly what's going on in each of these...

But short-term they should probably go in, a little slower and safe is
better than ultra-fast and wrong.
