Some effects, such as ShellBlurEffect and ClutterOffscreenEffect, need to make sure the actor is painted fully opaque. With ClutterActorNode, however, that is currently not possible. Add a new 'opacity' parameter to clutter_actor_node_new(). It follows the opacity override heuristic, where -1 means disable, and anything else is clamped to [0, 255]. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1340
