The CCLayerTreeHost family of classes have a hack in them that allows main-thread code to get to the skiaContext in order to keep accelerated painting working.

This is a violation of layering --- we do not want anything on the ContentLayer side to ever have access to LayerRenderer, GraphicsContext, or GrContext state.
