    window: Don't send startup notifications for offscreen / popup windows
    
    The WM isn't aware of O-R (popup) or offscreen windows. If somebody
    maps an offscreen or a popup GTK+ window before the main window, we'll
    complete the sequence before a "real" window is mapped. Make sure to
    ignore these for startup notifies.
