I'm wondering if there is any way to avoid this as public function on a client
facing class.

I think we will want to expose GrResourceCache, or really some narrower wrapper
on it, as a public interface available from GrContext for clients that want to
write their own GrEffects. That would serve the needs of this change I think,
but maybe that's another little project.

In the meantime maybe we could move this to private and friend GrPath? It'd be
ugly but I think I'd prefer that to exposing this function.

Done.
