resisdue is actually interleaved in a normal stereo vorbis file, it's just 
deinterleaved during decoding. I am guessing the reason for not interleaving 
by default - although it would be faster and more memory efficient - is that 
it would lead to more complex code (always doing every operation, like imdct, 
on interleaved vectors).
