There are two changes. 1. It is redundant to call GraphicsLayer::removeFromParent() or GraphicsLayer::removeAllChildren() before deleting GraphicsLayer, because the destructor of GraphicsLayerTextureMapper does those. 2. LayerTreeRenderer::setRootLayerID() does not need to remove all children of rootLayer because this method can be called only once.
