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