Hello, I am having some problems migrating from 2.1.1 to 2.1.2. When I run
the 2.1.1 demos, CompoundGraphDemo for example I get graphs of subgraphs
all drawn out with nodes and edges. This is all fine except I can't figure
out why when I run the same demo in 2.1.2 I get edges drawn between the
upper subgraphs and the first and last nodes in each subgrap. I.e., why
does node 1 have an edge to the subgraph that contains it?

The graph stuff is new to 2.1.2, despite the fact that you may have
downloaded previous versions of GEF labeled 2.1.1.
This is probably a bug. The way we perform the crossing reduction involves
adding new edges to the graph. We remove some of them later on, but we
don't remove all of them (anymore), so you see them in the demo. We should
probaby modify CompoundDirectedGraphLayout such that it removes all of these
"containment" edges. As a workaround, you can just ignore the edges which
you yourself didn't create.
