Nothing on a branch yet; I'll be building a temp branch for my changes
First, I'm eliminating ordering dependancies in vorbis_block
structures. They'll be totally sepreate and vorbis_analysis won't
have a global state in vorbis_dsp_state that requires them being done
in order. That way, a parallel-threaded encoder can run multiple
vorbis_blocks through multiple simultaneous calls to vorbis_analysis.
Second, psy.c is almost entirely new code. That from Segher's patches
I couldn't apply directly is 'applied' in spirit. I haven't gotten to
patch 3 yet; he's patching faster than I'm getting my own code done
Next, I'm doing an additional FFT for more stable tone amplitude
determination in the psychoacoustics.
...and adding residue backend 1 for noninterleaved vector construction
within residue vector partitions.
Lastly... [drum roll please]: first cut channel coupling (mapping 1).
So, try not to go *too* nuts in psy.c right now.
