  Message : Add destroy hooks for several GL objects. These hooks allow the back-end renderer to free object resources without having to store pointers to shared device handles for each and every object. This will allow us to save memory on back-ends that really care about memory overhead. There is a downside in that there is more boilerplate in passing gl::Context handles around everywhere.
