Sure! We support both OpenGL 2.1 and OpenGL ES 2.0 as back-ends, and ES is the best since it's closest to the WebGL API (using OpenGL 2.1 forces us to do quite costly emulation in a few cases, especially when drawing with vertex attrib 0 array disabled).

Naive question --- how do we get a GL ES context: through GLX, or EGL?
