629750290f avoid overflow in the 3rd lifting step, this now needs mmx2 at minimum 
(patch for plain mmx support is welcome ...)

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

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.

3a9f44d5d5 and of course the unneeded double subtractions were blindly put in the 
mmx code
this also makes the affected code 4% faster
