    gtk-clutter-actor: fix inconsistent condition in actor update
    
    Using the gdk backend of Clutter, you could end up in situation where
    none of the embedded widgets were being displayed. That's because the
    conditions for invalidating the canvas where inconsistent with the
    rest of the code.
