Grouping with EfficientSugiyamaLayoutAlgorithm as layout algorithm for groups

[dijkstra33]

Good afternoon. Thx for your work around the library.
Grouping with RandomLayoutAlgorithm as LayoutAlgorithm for AlgorithmGroupParameters works fine for me, but grouping with EfficientSugiyamaLayoutAlgorithm just draws one last group and skips others. I use your standard GroupingLayoutAlgorithm<TVertex, TEdge, TGraph> as ExternalLayoutAlgorithm for core logic. Code with random group layout algorithm works with code from your project ShowcaseApp.Wpf in LayoutGrouped.xaml.cs. Is there any way to bring efficient sugiyama in my groups ?

Sorry, I read source code and find out what I am doing wrong. There is quite nice support for efficient sugiyama in grouping.
