The old check for using NEAREST by checking clutter_actor_is_in_clone_paint() and meta_actor_is_untransformed (actor) doesn't work properly since clutter_actor_is_in_clone_paint() does not look at ancestors of the actor; it only applies to a direct clone of the actor. Using meta_actor_painting_untransformed() allows us to check exactly what we care about rather than using tricky approximations. https://bugzilla.gnome.org/show_bug.cgi?id=735632
