cairo-perf report


Attached please find a diff report generated by running "make check" in the
perf directory with the following two test cases:

1) cairo without USE_MEDIALIB defined
2) cairo with USE_MEDIALIB defined

Then I ran cairo-perf-diff-files to generate the attachment. 

I think it shows that many (about 30) functions have 5-14% speedup, and many 
other functions have smaller speedups. 

It seems two functions are slightly slower (paint_similar_rgb_source-512 is
6.27x slower and stroke_solid_rgb_source-128 is 4.02x slower though going from
9.39 to 9.47 doesn't really seem that significant to me).  There are a few
other slower functions, all below 1.57x slower, which is probably not
significant.

I think this shows that the patch, overall, improves performance significantly.
 Can this now go upstream?
