    window: Don't save state when tiled
    
    The saved window state (whether the window is maximized and its initial
    size) should be the state, that the user would most likely want the next
    opened window to start with. As the tiled state doesn't make sense
    without other windows and because it's not really possible to properly
    restore it, it will not be saved anymore.
