MMX dither code mangles global vars, shouldn't.

MMX code has variables in the context not ifdeffed, shouldn't.

I'd rather have the mmx code shuffled away completely (c.f. nodame 
branch) before addressing those gory details. Having the swscale C 
implementation clean is a better starting point than trying to address 
the x86 hacks first.

lu - maybe because I'm not using such arch...
