    x11: Copy from actual window, not parent
    
    This code is a relic from GTK2 days and should not be necessary anymore,
    as code now makes sure to only copy those parts of the window that are
    not overlapped by parent windows.
    
    By deleting it we fix potential issues with composited and translucent
    windows copying the wrong data.
