Yeah, it's the same problem in a bunch of places (but, hopefully we can fix them all simultaneously).

Yeah, it's not great :( I wanted to try to cast to a RemoteImageBuffer, but that's a templated class. I think that ideally, RemoteRenderingBackend would know about the RemoteImageBuffers it can paint into (instead of always digging it up from the resource cache).
