The polyline the layout routed for one edge, in absolute coordinates:
the section start, every bend, then the end. ELK's orthogonal router
routes these AROUND nodes, so a renderer that follows them verbatim
(Cytoscape segments) does not pass an edge behind a block. Present
only when the layout ran with routeEdges (the default); absent when a
consumer opts back into endpoint-only routing (e.g. Cytoscape taxi).
