A DtOverlayPolygonEmbarkationUpdater is a specialized DtMultiPointEmbarkationUpdater that manages the unique method by which overlay polygon vertices are updated.
For other multipoint objects, vertices are kept in the scene object (for a four point object, e.g., the vertices would be set calling DtSceneObject::setPosition( 0, ... ) through DtSceneObject::setPosition(3, ... ). The overlay polygon, however, needs to have the actual model vertices updated, using polygon->setPoints() as well.
