[vtkusers] Overlapping (hidden) edges in graph visualization

[David Doria]

Here is a graph I recently produced:
http://rpi.edu/~doriad/VTK_List/OverlappingEdges/graph.jpg
(using this code:
http://rpi.edu/~doriad/VTK_List/OverlappingEdges/DanielGraphColoring.cxx)

There is an edge of weight 80 between vertex 1 and 5. You can see the
text "80" near the middle of the graph, but you cannot tell where the
edge is! The edge between vertex 6 and 7 is weight 2. Is this a bug?
Or is there a mode that will not hide edges like this?

Thanks,

David
