    native-window-placement: update for latest gnome-shell changes
    
    Recently gnome-shell changed the code to handle the window overlays
    (to fix some bugs aboud the overlay flashing), which resulted in
    invisible overlay with this extension. Fix by reimporting some code
    from gnome-shell core.
