[vtkusers] vtkCellPicker

[David J. Netherway]

I downloaded the 15/8/00 version of VTK (even though there was a catastophic
failure VTK seemed as functional as ever) and
found that there was still a problem with the use of cellPicker and the use of
a single cube source
for mulitple actors positioned using SetPosition.

The work around is to have a source for each actor.
