If we can reach feature parity then this sounds OK. In retrospect maybe
I should have worked on improving libopenjpeg performance instead. Oh
well.
We need the HT stuff in, and also my threading patchset rebased and
pushed as well. Else we'll have worse performance than opj. With my
patchset, and a bit of work on Caleb and pal's patchset, then we might
be able to bring j2k performance (both part1 and ht) far above opj
There may be some other details as well regarding features of j2kdec vs
opj but I forget
