  // Description:
  // This painter overrides GetTimeToDraw() to never pass the request to the
  // delegate. This is done since this class may propagate a single render
  // request multiple times to the delegate. In that case the time accumulation
  // responsibility is borne by the painter causing the multiple rendering
  // requests i.e. this painter itself.
