Yeah, and i'd even say that ffmpeg and skal's versions are very
similar, a good exemple of code developed independently that all in
all, is quite the same.

When using no VHQ, the DCT is very small part of total encoding time,
but when playing with VHQ>=2, last time i profiled xvid, the fdct was
taking more importance in the flat profile.
I'll probably remove the old dct code, and keep only the skal or the
ffmpeg version depending which one is faster.
