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 git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@2265 b3059339-0415-0410-9bf9-f77b7e298cf2
