[Paraview] Filter input types

[Jérôme]

Hi Fred,

Quoting from the vtkPolyDataAlgorithm doc:
"This class also provides a FillInputPortInfo method that by default says
that all inputs will be PolyData. If that isn't the case then please
override this method in your subclass."

You will find a lot of VTK classes that override the
FillInputPortInformation method. It shouldn't be too difficult.
