[theora-dev] dead DCSearchPoints code

[Dan Miller]

hi Mike --

I'll take your word for it.  You've gone deeper into the code than I have at this point.  If you're up for helping with the spec, I certainly could use some.

Speaking of dead code, there's junk in huffman.c that can be removed -- I posted about this before.
