d604bab901 fixed alignment (static variables where sometimes not 8-byte aligned) 
added half uv interpolation support
added prefetch
BGR15 support in MMX (untested) (so BGR15,16,24,32 are supported)
special unscaled height version (not much faster but it doesnt interpolate uv vertically)

783e9cc9af increased precission of s_xinc s_xinc2 (needed for the mmx2 bugfix) 
moved mmx variables to top to avoid alignment issues
mmx2 code should work fine now if and only if the input width is %16=0 and the output width is %32=0
reordered some code (5% faster with a simply -benchmark)
first line bug fixed (i hope i didnt introduce any new bugs with that ...)
changed a lot of the vertical scale setup code, i hope i fixed something and didnt mess it up :)
a few known bugs left (rightmost line is wrong)
MMX2 code will only be used for upscaling & acceptable width´s
16bit dithering can be disabled
