    Persistence adapter for wxTopLevelWindow.

    This adapter saves and restores the geometry (i.e. position and size) and
    the state (iconized, maximized or normal) of top level windows. It can be
    used with both wxFrame and wxDialog.

    Note that it does @em not save nor restore the window visibility.
