[vtkusers] How to remove points/handle from one vtkDistanceWidget or vtkAngleWidget?

[Arnaud GELAS]

Actually I am more interested in being able to reinitialize these widgets.
For instance, when you want to measure different objects that are far 
apart, and I guess it would be faster to reinitialize the widget than to 
drag these points to another part of my image (quite far from here).

How should I proceed?

Thanks,
Arnaud
