    GtkWindow: default size is only for initial map
    
    Bring back need_default_size. We need it to preserve this
    documented behavior:
    
    The default size of a window only affects the first time a window is
    shown; if a window is hidden and re-shown, it will remember the size
    it had prior to hiding, rather than using the default size.
    
    With this patch, all of the window sizing tests in
    gtk/tests/window pass again.
