mojo.Surface's client had two methods: *) SetIdNamespace replaced by mojo.Surface.GetIdNamespace which returns the id namespace via a callback. *) ReturnResources split into a ResourceReturner interface which can be (optionally) set on the mojo.Surface via mojo.Surface.SetResourceReturner Also beefed up the comments a bit.
