[vtkusers] updated image from vtkImagePlaneWidget

[Julien Finet]

You can use 3 vtkImageViewer2 to display your planes in 2D:

vtkImageViewer2::SetInput(my3DImageData)
vtkImageViewer2::SetOrientation(XY or XZ or YZ)
vtkImageViewer2::SetSlice(slice)

With your 3 3D orthogonal planes, add the observers:
myOrthoPlane1->AddObserver(vtkCommand::InteractionEvent,myCallback);
myOrthoPlane2->AddObserver(vtkCommand::InteractionEvent,myCallback);
myOrthoPlane3->AddObserver(vtkCommand::InteractionEvent,myCallback);

myCallback(vtkObject* vtk_obj...)
{
  vtkImagePlaneWidget* planeWidget =
vtkImagePlaneWidget::SafeDownCast(vtk_obj);
  //use a mix of
   planeWidget->GetPlaneOrientation()
 //and a mix of
  planeWidget->GetSlicePosition()
 //to update your 2D imageviewer corresponding to the 3D plane widget
  my2DImageViewer->SetSlice()...
}

Hope it helps,
Julien.
