[Paraview] pvti example with data in cells question

[Sergi Mateo Bellido]

Hi Nikolay,

I don't know if you still have this problem, if it's fixed feel free to 
ignore this email :)

I think that the main issue is that you are specifying the whole extents 
of the VTI files (i.e. 1.vti and 2.vti) as if they were independent, 
instead of specifying the part of the whole image they occupy (I had a 
similar problem and they told me that).

Another thing that I'm not sure if it is ok is how you describe the 
whole extents: I was told that if you want to declare a 4x2 model the 
whole extent should be  0 3 0 1 0 0.

Best regards,
Sergi
