The ClutterRootNode paint node is theoretically the top-most node of a paint nodes tree, except that we are not in the point of having full rendering trees in Clutter (all rendering performed by paint nodes is still local and immediate). When controlling the rendering tree, MetaShapedTexture may need to paint into an offscreen framebuffer under some circumstations. Expose ClutterRootNode so that MetaShapedTexture can use it to render to offscreen framebuffers. https://gitlab.gnome.org/GNOME/mutter/merge_requests/405
