cairo-gl-sdl2

This project is a test bed for using Cairo, SDL2, and GL/GLES2 together. It differs from existing projects in that it uses the new (ACTUAL) OpenGL Cairo backend, which has recently received a lot of development attention.

I have found it to be almost twice as fast as the image backend, though it can be up to triple the speed in some cases.
