[vtkusers] mirror image of poly data

[David Gobbi]

Hi Sarika,

It's a two step process.  First use vtkTransformPolyDataFilter
with a vtkTransform that does a flip -- use transform->SetScale(1,1,-1)
to do create the flip in e.g. the Z axis.

Then put the output of vtkTransformPolyDataFilter into vtkReverseSense
to fix the orientation of the polygons.
