The raw buffers are our own construct and as such hardly an argument for that.
If you mean that in the bitstream the most inner loop iterates over the samples
of a given block of a given channel then, well, one might argue that planer is

Sound like a good way to handle it.

However, I think we can let the user decide what output format he likes, don't

follow you on just replacing it (assuming the former is true). I'd also be ok
with defining planer output to be the default in that case.
