    data: don't expose window shading shortcut
    
    GTK+ doesn't support shading of client-side decorated windows, and likely
    never will (not least because shading is conceptually questionable if the
    app customizes the titlebar), and neither do other CSD implementations like
    Chromium's. A shortcut that only works with a decreasing number of windows
    is more confusing than helpful, so don't expose it.
