Polyline or curvy edge support?

[<vili.auvinen AT jyu.fi>]

Hi,

Do you have any schedule for implementing polyline or curvy edge support?

I have a directed hierarchical layout (like a process model) and I would like
to add edges that do not overlap with nodes. I would like to use your library
but the lack of this feature is holding me back.

I thought of using the dot layout from graphviz and utilize its coordinates 
for
nodes and edges. There's a GraphicEdge class that has control points - would 
it
be possible to implement that way?

Thanks,

  Vili
