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

6d324c813f Statements like a = b = c = d = e; store from right-to-left, so if
you write them in the right order it comes out backwards.
This removes them from fill_rectangle().

Necessary for systems that don't align by default to 16 bytes, required by some
SSE instructions.
