I'm not sure what your question is, but I'd be glad to help answer it
if that would be easier than browsing through cairo's source code.
Cairo does tessellate complex polygons into a set of trapezoids for
XRender to rasterize and composite. And Render does guarantee that the
antialiased rasterization of trapezoids with shared edges will combine
to exactly 1 so that there are no visible internal seams.
Is there something else that you have a question about?
