[Paraview] Making vtkImageMathematics available in ParaView filters

[Jérôme]

Dear all,

I am unsuccessfully fighting with XML description of the VTK
vtkImageMathematics filter. I want it to be available in the ParaView
filters. At the end of this mail is the XML I wrote, widely inspired from
"Append Geometry".

Note that it is part of a larger file making available ImageGaussianSmooth,
ImageSobel3D, ImageFilp, SplineFilter, some different sources... Everything
works well, except Image Mathematics and Image Reslice (I told about Reslice
in another thread).

The symptom is the following : the "Image Math" appears in the filters list,
but is always unavailable, even if I select one proxy or two in the
pipeline. What is the diagnostic, doctors ? Is there a therapy ?

Thanks all !

Best regards,
Jerome
