The PIPointChangesCookie is used in subsequent calls to FindChangedPIPoints(Int32, Object, PIPointChangesCookie, IEnumerablePIPoint) to retrieve changes that have occurred, since the last call was made. This object is serializable, so that consumers can serialize the object before shutdown and reconstitute it on startup.
