        !             9: *
        !            10: *  The CPoint object exposes two properties for programatic access
        !            11: *  via the IDispatch interface.
        !            12: *
        !            13: *  properties:
        !            14: *    X                         - the 'x' coordinate of the point
        !            15: *    Y                         - the 'y' coordinate of the point
