Cairo-related resources

I contribute to the Cairo graphic library, a 2D cross-platform vector library which provides a unified interface to draw on multiple output devices.
Cairo is deeply linked to Pixman, the pixel-manipulation library used in the X.org server.
I maintain a buildbot to track check for regressions in Cairo and Pixman.
My main contributions to Cairo are the implementation of mesh gradient rasterization, improved compatibility between PS/PDF shadings and Cairo patterns and fixes for the Quartz backend.
