Your patch is pretty much what my patches did, except
you wrap dct32, while I get rid of it, and I also did it one
component at a time rather than getting rid of all of it
at once. I have no objection with the way this is done either way.

I'd just like some credit for deleting something I spent
years researching and replacing. After all, it's easy to remove
entire files at once and being first, but less so figuring out how
to write fast and reasonably small DCT-I/DST-I transforms.
