[Paraview] Hidden Properties for Plugins

[Christian Werner]

Hi!

I'd like to know if it is possible to set properties to some value 
without letting the user change that. This would be nice, since e.g. the 
vtkImageGaussianSmooth requires a call "SetDimensionality" to setup 
whether to use a 1D, 2D or 3D Gaussian Smooth. Depending on that the 
user has to provide one, two, or three values for the 
StandardDeviations. So I chose to make a 2D version and a seperate 3D 
Version where I provide 2, repectively 3 input fields for these values. 
The SetDimensionality should then be called properly without the user 
having to take care about that.

Best regards,
Christian
