michael df864731f8 15/16 bit dithering in C (5% slower, can be disabled by comenting #define DITHER1XBPP out)
x/yInc bugfix (bug was introduced during the global var removial)
more emms & no messing with ARCH_X86 (=workaround against not cleared mmx state somewhere)
sharpening filter (-ssf cs=<int> & -ssf ls=<int>)
