not header parsing. vp3 used static (builtin) tables, while theora allows
the encoder to build the optimal tables, and the store the tables in the
header. it may be a big improvement in vq-based codecs like vp3.

probably it took so long to take the very messy win32/mac targetted vp3
sourcecode and transfer it to even more messy libogg-dependent shit.

also, they probably work a lot on improving the encoder, ie. adding the
ability to build optimal tables.
(this is the key thing, see mp3 for example, there are several mp3 encoders,
from ffmpeg, though xing to l3enc or lame, with huge quality difference,
they all enoe to teh same format (same decoder can be used) but i bet there
is big work behind the mp3lame code)
