Callback function for custom feedback while editing polygons.

    typedef void  DelPolyNodeProc (



You should implement this function if you have to give graphical feedback for the input operation invoked from your API tool add-on. This callback routine should be passed as a parameter when calling the APIIo_GetPolyID interface function. During the input process your procedure is called when the user deletes a node from the polygon.
