I fixed those long long time ago; some may have crept back
in.  I'll go see.

M_PI *used* to be defined to a single precision constant.

Maybe I should open source my Vorbis decoder, it has a
neat split between setup and block decode.  And no traces
of encode side, of course ;)

A very handy way to get rid of encode is to first get rid of
the encode data structures -- you'll quickly find out what
routines should go away.

As an aside, I'd like to clean up libvorbis, but then I'd
like it very much if someone else would merge Tremor back
into that codebase.

Any takers?
