Looks good, do you mind splitting them up into the separate logical
chunks, and moving _cairo_bo_point32_compare() into the test code as we
remove its only caller? The split I'd like to see is the optimised sort,
the inling of point_cmp, the 'else if' for combsort, and two code
rearrangements (individually).

Also it would be nice to have a summary of any observable differences
(even just callgrind results). Thanks,
