I'm having trouble getting an mitk::Contour object show up in a
QmitkRenderWindow :

Starting the step2 tutorial, after the image files get read in I've added
this:

    mitk::Contour::Pointer contour = mitk::Contour::New();
    contour->Initialize();
    contour->SetClosed(true);
    contour->SetWidth(1.0f);
    float data[][3] =
    {
      {70.7, 93.1, 0},
      {79.23, 1.633, 0},
      {4.83, 5.767, 0},
      {21.9, 1.367, 0},
    };
    for (int i = 0; i < 4; ++i)
    {
      contour->AddVertex(mitk::Point3D(data[i]));
    }

    mitk::DataNode::Pointer contour_node = mitk::DataNode::New();

    contour_node->SetName("Contour");
    contour_node->SetData(contour);
    contour_node->AddProperty("color", mitk::ColorProperty::New(0.f, 1.f,
0.f));
    contour_node->AddProperty("visible", mitk::BoolProperty::New(true));
    contour_node->AddProperty("Width", mitk::FloatProperty::New(3.0f));
    contour_node->AddProperty("project", mitk::BoolProperty::New(true));
    contour_node->AddProperty("layer", mitk::IntProperty::New(0));

    storage->Add(contour_node);

When I run the project nothing appears in the renderwindow.  Any hints on
what I maybe missing?

I'm using MITK from SVN pulled late last week, ITK v3.16, and VTK v5.4.2
