Considering the image benchmark from: http://flashcanvas.net/examples/dl.dropbox.com/u/1865210/mindcat/canvas_perf.html the proposed patch has the following results:

Nix: ~15% gain;
GTK: ~10% gain;
EFL: ~10% gain;

We also did tests with Nix using image low interpolation quality. The gain was ~50%.
