This property affects the following methods: GetFromLinkDir, GetToLinkDir, GetFromLinkPoint, GetToLinkPoint, and GetLinkPointFromPoint.
When this static/shared property is true, any link inside a collapsed GoSubGraph will appear to be redirected to the first visible collapsed parent subgraph, if that subgraph has a GoSubGraph.Port. Note that no structural changes are made to any ports or to any links -- only the point and direction at which links connect, so that they will now appear to be connected to the subgraph port. Also please note that by default GoSubGraph.CreatePort returns null/nothing, so a subgraph will not have a port unless you either override that method to return a new port or you assign the GoSubGraph.Port property.
