        UI scale is an SD only feature.  The UI scale is represented by items
        ATTR_OPTIONS_SCALE_X and
        ATTR_OPTIONS_SCALE_Y.
        As we have no direct access (there is no dependency of svx on sd) we have to
        use a small trick (aka hack):
        a) call this method whenever a change of the metric item is notified,
        b) check if the UI scale has changed (strangely, the UI scale value is available at the SdrModel.
        c) invalidate the items for position and size to trigger notifications of their current values.
