[vtkusers] Image tracer using Qt

[Arnaud Gelas]

Hi Luis,

I recommend you to have a look at vtkContourWidget, you can easily get 
the same functionalities as the vtkImageTracerWidget (except the free 
line tracing).
The code vtkContourWidget is awesome, very clean!!! It offers a lot of 
functionalities and possibilities via vtkContourRepresentation, 
vtkPointPlacer and vtkWidgetEventTranslator. 
<http://www.vtk.org/doc/nightly/html/classvtkWidgetEventTranslator.html>..
Then as Wagner, the integration with Qt is straightforward.

Regards,

Arnaud
