• this method is called outside of view, instance and link begin/end calls but still between OnElementBegin2D/OnElementEnd2D calls
• this method is never called for annotation elements, i.e. their geometry should be processed in methods OnCurve and OnPolyline

This method is called when a Polyline is being output.

This method is called after unhandled curve was tessellated to polyline segments and sent to the output.
