This code is implemented as a filter for oggenc - it inserts itself
into the processing pipeline. See setup_pan() and read_pan(). And
remember to use the new version - it now supports up to 3rd order.

This list is definitely correct if we talk about people who can
improve Vorbis codec, but the question is whether they want to.
Vorbis' surround application stands in its place from at least five
years; there were no common tools to easily encode/decode Ambisonics
till now.
