-To handle this case a special type of edge is inserted. The edge to/from the cluster is replaced with an edge to/from a node in the cluster which is tagged with toCluster/fromCluster. When rendering this edge the intersection between the edge and the border of the cluster is calculated making the edge start/stop there. In practice this renders like an an edge to/from the cluster.
