gl-renderer: compress pixman bands to simplify geometry

Pixman uses y-x banded rectangles to represent regions.  We use these
y-x banded rectangles to generate triangle fans, resulting in more
geometry than strictly necessary to draw the screen.

This patch combines the bands to reduce geometry for complex scenes.
