20646267cd Another (final?) patch for libpostproc.
This one replace horizClassify by a
transpose/(use Vert)/transpose sequence.
This add LowPass and DefFilter for "free".
I also fixed the header in postprocess.c
and special-cased some of the well-aligned
cases (all horiz stuff is well-aligned).

a7b2871cd1 Newer version, using a vectorized version of the
new organisation of code in doVertLowPass. it
seems to be faster in AltiVec also...

Also includes a compile fix for the new do_a_deblock
when using AltiVec.
