Node BoundaryCurve has no effect

[bbenami]

I'm trying to define the size of a node explicitly. I've tried setting the label width/height as well as setting the node's boundarycurve. Both does to seem to make any effect of the node size.
Below is my sample code.
What am I missing?

        Microsoft.Msagl.Drawing.Graph graph = new Microsoft.Msagl.Drawing.Graph("");
        graph.AddEdge("A", "B");
        graph.AddEdge("B", "C");

        int nwidth = 100;
        int nheight = 100;

        var geometryGraph = graph.CreateGeometryGraph();
        var n = graph.FindNode("A");
        n.Label.GeometryLabel = new Microsoft.Msagl.Core.Layout.Label();
        n.Label.GeometryLabel.Width = nwidth;
        n.Label.GeometryLabel.Height = nwidth;
        n.Label.Width = nwidth;
        n.Label.Height = nheight;
        int r = n.Attr.LabelMargin;
        n.GeometryNode.BoundaryCurve = CurveFactory.CreateRectangleWithRoundedCorners(nwidth + r * 2, nheight + r * 2, r, r, new Point());

        graph.Attr.LayerDirection = LayerDirection.LR;
        geometryGraph.UpdateBoundingBox();

        Microsoft.Msagl.GraphViewerGdi.GraphRenderer renderer = new Microsoft.Msagl.GraphViewerGdi.GraphRenderer(graph);
        renderer.CalculateLayout();

        int width = 1500;
        Bitmap bitmap = new Bitmap(width, (int)(graph.Height * (width / graph.Width)), PixelFormat.Format32bppPArgb);
        renderer.Render(bitmap);
        bitmap.Save("c:\\temp\\test.png");

It seems GraphRenderer creates new geometry blindly, even when the drawing graph already has the geometry associated with it. The way to control the shape of the nodes is to use a delegate for the geometry node boundary curve: the code below demonstrates it:
` Microsoft.Msagl.Drawing.Graph graph = new Microsoft.Msagl.Drawing.Graph("");
graph.AddEdge("A", "B");
graph.AddEdge("B", "C");

            int nwidth = 100;
            int nheight = 100;

            var n = graph.FindNode("A");
            int r = n.Attr.LabelMargin;
            n.NodeBoundaryDelegate = new DelegateToSetNodeBoundary(p => CurveFactory.CreateRectangleWithRoundedCorners(nwidth + r * 2, nheight + r * 2, r, r, new Microsoft.Msagl.Core.Geometry.Point()));

            graph.Attr.LayerDirection = LayerDirection.LR;
            
            Microsoft.Msagl.GraphViewerGdi.GraphRenderer renderer = new Microsoft.Msagl.GraphViewerGdi.GraphRenderer(graph);
            renderer.CalculateLayout();

            int lwidth = 1500;
            Bitmap bitmap = new Bitmap(lwidth, (int)(graph.Height * (lwidth / graph.Width)), PixelFormat.Format32bppPArgb);
            renderer.Render(bitmap);
            bitmap.Save("c:\\tmp\\test.png");`
