Maybe. Can I poll the current state for what renderer is active? I'd need to
ungrab until the current renderer is the top-most one. I'm not sure we can
currently do that. What we can do is ungrab until we get a error... but that
would mean a custom error handler in my error printing code.

Something tells me that's a very, very bad idea :¬).
