[vtkusers] Problem about vtkPicker

[Francois Bertel]

Hi,

You can control that on the actor, more exactly the superclass of
vtkActor, vtkProp has a Pickable flag. Initially its value is true.

Just set this flag to false to all the vtkProp objects you don't want
to pick and keep it to true on the vtkProp handling the vtkPolydata
you want to pick.
