It would be great to be able to choose (and possibly switch) the shape of the graph nodes to rectangles as in the early days of the project

it is possible to choose a rectangle (box) as a shape. Still there are some issues: * in directed graphs the arrows of edges are not drawn correctly * the size of the box should be computed based on font size, now 12 is assumed

It is now possible to switch stencil in the edit dialog, since revision r204.
