[vtkusers] Wierd behaviour of vtkClipPolyData and vtkGaussianSplatter (reproducable with Paraview)

What are the parameters on your vtkGaussianSplatter? My guess is that you
are using the default settings for the vtkGaussianSplatter and that the
model bounds are starting at the origin and extending into the positive
side of the origin in all three dimensions while your data has positions on
the negative side of the origin. You will probably have to adjust the model
bounds to make sure they are large enough to contain your clipped poly data.
