GL: Missing check for texture format sample counts ANGLE was hitting an issue running on llvmpipe because llvmpipe doesn't properly implement texture formats with multisampling, but claims otherwise to be OpenGL 3.3 compliant. ANGLE did not validate the claim on the backend, so the frontend was hitting an ASSERT that failed. This patch makes sure to validate this part of the spec, and limits the driver to OpenGL 2 if it's not conformant.
