<P>
        If supported, this method sets the clipping <b>regions</b> that are used to
        to enable or disable visibility of parts of the layer. The <b>num_regions</b>
        must not exceed the limit as stated in the display layer description.
 </P><P>
        If <b>positive</b> is DFB_TRUE the layer will be shown only in these regions,
        otherwise it's shown as usual except in these regions.
