IMO the only proper orders place L and R at the beginning so that
truncation will result in valid (albeit very poorly balanced) output
for stereo. If you're going to standardize on something, please make
it something with L and R first.

BTW my intent was that we should eliminate "packed" audio altogether,
and refit all the decoders to output each channel as a separate array,
like the way video planes are handled. This way reordering would never
be required and remapping would just be a matter of permuting the
channel pointers rather than munging the data.
