Thanks for the patches. I have pushed them to master with a few
formatting fixes.
However, you should get a freedesktop account so that you can push
patches yourself, or at least, if you want me to merge them, provide a
public git repository that can be pulled from.

Did you do any measurements of this one? As Siarhei said:
As for the performance numbers. I wonder how much faster would these
new specialized MIPS fast paths be if we had a DSPr2 optimized OVER
combiner? You can check "sse2_combine_over_u" and
"neon_combine_over_u" functions as examples of existing combiners.
