Mutter needs to know which framebuffer the paint nodes will be drawn into, and using cogl_get_draw_framebuffer() directly is not an option since ClutterRootNode only pushes the draw fb at draw time. Expose clutter_paint_node_get_framebuffer(). https://gitlab.gnome.org/GNOME/mutter/merge_requests/409
