Would it be sensible to wrap the glGetError call like this?

GLenum
glamor_check_gl_oom() {
        GLenum last_oom = GL_NO_ERROR;
        GLenum error;

        while ((error = glGetError()) != GL_NO_ERROR) {
                if (error == GL_OUT_OF_MEMORY)
                        last_oom = error;
        }
        return last_oom;
}

I admit I haven't looked at the Mesa glGetError() implementation, so I
don't know if there's a queue of errors, or just a bitfield.
