[vtk-developers] vtkCleanPolyData

[Andy Bauer]

I did something similar to this for a different filter (I can't remember
which one) and I don't think it even broke any of the tests.  I can't
remember if I provided an option of the return precision type or just used
the input precision type to specify the return precision type.
