LayerRendererChromium is a compositor thread-side class, so Canvas(2D)LayerChromium should not have access to it, except during updateCompositorResources.  The DrawingBuffer creation and destruction and its interaction with the LRC are probably the largest problems here.  The removal and addition of child contexts will have to be deferred until the next commit and stored somewhere (CCLayerTreeHost?).
