Fixed issue with vtkPointSet::FindCell().
Fixed issue with vtkPointSet::FindCell().

FindCell() has a quick check to short-circuit if the point
is outside the bounds of the dataset. This check was not taking
tolerance into account and failing for certain datasets, specially
2D ones where points are double precision. Fixed by taking
tolerance into account.
