[vtkusers] vtkDistanceWidget

[Arianna Forneris]

Hi everyone, I solved the problem that I had with the vtkDistanceWidget…I was
getting wrong measurement since that the widget seemed to be related to the
window but not to actual image where i was trying to measure. the problem
turned out to be related to the actor: i was using a vtkActor2D in order to
visualize the DICOM image and it didn't work correctly but now I'm using a
vtkImageActor and it works perfectly. Hopefully this suggestion will help
someone else!
