  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.
