This is the only way to sync TextureMapperLayer and GraphicsLayerTextureMapper known to us at the moment, although it appears to be a bit messy. If there's a better way to do that could you please share your thoughts then? If it's critical we could try searching for other ways. But nevertheless we'd like to point that GraphicsLayerTextureMapper doesn't get passed to flushCompositingStateSelf as const, and that's why it's prone to changes inside this method.
