Hi,

It seems the executable linked to the wrong version of the library 
because I had another version of cairo installed because of Gimp. So the 
benchmarks I gave were actually for 1.4.2 and not 1.6.4 as I had 
thought. I have now re-run all the tests again using 1.6.4 (which I 
checked with cairo_version_string function). Here are the new results:

~     DrawHorizLine              15839 ms
~     DrawHorizLine with alpha   30967 ms
~     DrawVertLine               17591 ms
~     DrawVertLine with alpha    17466 ms
~     DrawDiagonalLine           114979 ms
~     DrawDiagonalLine alpha     96101 ms
~     DrawFilledRect             1751 ms
~     DrawFilledRect with alpha  1664 ms

Although these figures show some improvements over 1.4.2 they are still, 
unfortunately, much much slower than our implementations.
