[vtkusers] Problem using vtkDistanceWidget

[Karthik Krishnan]

The distance widget by default uses the vtkDistanceRepresentation2D
prop which is a Actor2D and exists on the overlay plane. You either
need to enable/disable the widget manually by using some higher level
logic based on the slice -or- create another rep that where you manage
this internally by setting the image actor on this representation
