[Paraview] Volume rendering rectilinear data

[Weiguang Guan]

Hi David,

Thanks for confirming it. Does Kitware have a plan to implement volume 
rendering for rectilinear volume? You see the spectrum from 
vtkImageData, to vtkRectilinearGrid, vtkStructuredGrid --- volume 
rendering is implemented on both ends but not for the middle one, which 
is a bit odd to the user.

Best,
Weiguang
