     *  This method is typically used by layouts during measure() to predict what
     *  the element position will be, if the element is resized to particular dimensions.
     * 
     *  @param width The element's bounds width, or NaN to use the preferred width.
     *  @param height The element's bounds height, or NaN to use the preferred height.
