3e0f7126b5 update mmx code to latest snow changes
note, the code likely can overflow and thus needs some more changes
sse2 updated too but disabled as it is untested

d593e32983 use 16bit IDWT (a SIMD implementation of it should be >2x faster then with
the old 32bit code)

ce611a27be Change rounding of the horizontal DWT to match the vertical one.
This allows some simplifications and optimizations and should
not have any effect on quality.

61240ae556 fix chroma mc2 bug, this is based on a patch by (Oleg Metelitsa oleg hitron co kr)
and does slow the mc2 chroma put down, avg interrestingly seems unaffected speedwise on duron
this of course should be rather done in a way which doesnt slow it down but its better a few %
slower but correct then incorrect
