Not a chance.. I do not understand this at all. Please, advise.

What and how do I provide to the graph copies using StaticLayout so that the
vertex layout is similar to the original graph? In Joshuas answer it simply
seemed like all I had to do was pass the layout of the original graph.. However
that and any other wild attempt of getting it to work fails.. miserably.

This is what I do:

sl_ = new StaticLayout(topology_);
// sl_.initialize(new Dimension(600, 622)); // this works
sl_.initialize(new Dimension(600, 622), (VertexLocationFunction) orgLayout);
// this does not

This is what I get after doing the above:
