[vtkusers] Implementing a EdgePicker ...

[Sebastien Auclair]

Good idea but in our case it would meen too many actors !

We though of using vtkCells methods to estimate if a given point would be
near a cell of type "vtkLine" ...Something like that ...

We don't really know what to try !

Thanks anyway !
