ae1dbde1cf clip input motion vectors
be somewhat more tollerant on invalid input
return INT_MAX instead of -1 for unuseable mv/mb types as that ensures nicely that they arent used
initalize limits earlier for b frames
a few more asserts to check for out of picture vectors

0e9d4a67f4 change qscale -> lambda for the motion estimation
finetune bit/distortion weighting factor used in motion estimation, the old coeffs where finetuned relative to incorrect mv_penalty tables which where then fixed later but the coeffs where not
this _may_ fix the long standing blocking artifacts, but may also introduce mudding artefacts theoretically, so please tell us if u stumble across any so we can either fix them or export this variable so the user can change it

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.
