  Pass Context to Framebuffer11 dirty callback.
  
  This allows us to call StateManager11::invalidateRenderTarget from the
  Framebuffer11::signal function, which will then trigger state refresh
  on the next draw call.
  
  This requires passing Context through a few more Renderbuffer methods,
  and reorganizing the RenderTarget signalling so that it doesn't signal
  dirty in the destructor. Instead they are signaled as they are
  destroyed in the containing classes.
