  Message : Replace rx::Renderer with rx::ContextImpl. Previously Context had no Impl class, but had a special relationship with the instanced Renderer class. Having a ContextImpl backing every Context will allow new designs to enable things like multithreading (where each ContextImpl stores a Context-specific device) or non- virtual Contexts on Android or other platforms where it is more efficient. A large refactoring patch that touches every back-end.
