[Paraview] Enabling vtkSplineFilter in ParaView

[Jérôme]

Hi again !

I tried to replace the SplineFilter with a ProgrammableFilter
containing the following script :

input = self.GetInput()
splineFilter = vtk.vtkSplineFilter()
splineFilter.SetInput( input )
splineFilter.SetSubdivideToLength()
splineFilter.SetLength( 1 )
splineFilter.Update( )
self.GetOutput().DeepCopy(splineFilter.GetOutput())

This way, I am able to get a spline-based resampling. It means that my
XML description contains an error, but I cannot find it.
