63 * RenderProxy is strictly single threaded. All methods must be invoked on the owning
64 * thread. It is important to note that RenderProxy may be deleted while it has
65 * tasks post()'d as a result. Therefore any RenderTask that is post()'d must not
66 * reference RenderProxy or any of its fields. The exception here is that postAndWait()
67 * references RenderProxy fields. This is safe as RenderProxy cannot
68 * be deleted if it is blocked inside a call.
