ConnectorKeepInBounds Property

With AutoConnect=True, then the snapping action also allows the visual with the shortest connector (distance from Start to End) to slide along the length of the longer partner connector (on the other visual). The KeepInBounds property (of the longer connector) defines whether the longer connector will allow the shorter connector to extend its length beyond the length of the longer connector.
