[vtkusers] Line intersection with an actor

[David Gobbi]

The vtkCellLocator does this, but it operates on a vtkDataSet
rather than on an actor: actor->GetMapper()->GetInput()
The cell locator works in data coords rather than world coords
(use the actor's matrix to do the coord conversion, if needed).
