[vtkusers] Endpoints not follow distance line when moving

[kenichiro yoshimi]

Hi min,

Could you substitute vtkLineWidget2 + vtkLineRepresentation for
vtkDistanceWidget, etc.? I am not familiar with them, but as far as I
tried the
following example the endpoints of vtkLineRepresentation seemed to
follow the line properly. (Notice that there are options for distance
annotation in the vtkLineRepresentation)

Thanks,
yoshimi
