I've just put a commit in that:

 1) Removes the NDS specific copy of the blitters.

 2) Updates the blitters to use Carlo's algorithm (with a small tweak
that saves a cycle in the ARM code, and only uses it for
not-completely-transparent words).

 3) Uses a tweaked version of Max Horns C code.

I've only committed it on the trunk as I think I've missed the freeze
date for the release.

Any problems, please let me know.
