Visualising edges - how to find edge-node intersection when bend list is empty?

[M. H.]

Hi,

I'm turning to this mailing list once more as a last resort after failing to discover anything useful in the documentation.

I'm using SugiyamaLayout to lay out a graph which I'm subsequently visualising with Qt. 

With PlanarizationLayout the first and last bends of each edge are located at the intersection of the edge and the respective nodes, which is very helpful for drawing (the visualised edge doesn't cross into the node body). With Sugiyama, the bend list contains only actual bends in the edge - straight line edges have empty bend lists and thus don't allow me to draw edges starting and ending at the respective nodes' bounding boxes this way.

Is this intended behavior for this algorithm or a bug? If it is intended, can you suggest a way to determine the desired start/end points somehow?
