Screenshot results of the culling test

If gl.glEnable(GL.GL_CULL_FACE) is set, graph text rendering doesn't work with region MSAA or VBAA. It works ok with full scene MSAA or no anti-aliasing.

If it can't be made to work with culling, the quick solution would be to simply disable GL_CULL_FACE before rendering, and enable it afterwards, maybe via a new hintMask or custom enable/disable callbacks for renderer.

Not for now, perhaps on commission / contract.

Also note, we provide our own culling nowadays - and should be done in custom shader for the remaining app.
