[vtkusers] Volume rendering anomalies (looks like a bug)

[Paul Melis]

Hello,

With data file [1] and the attached Python script I get some really 
strange volume rendering results with vtk 5.2, using the volume ray 
caster (see the attached screenshots). The vtk file renders correctly in 
Paraview 3.4.0 and I have no volume rendering problems with vtk on other 
datasets. The dataset is a simple structured points file consisting of 
323 unsigned shorts (although the original dataset I had the same 
problem with was 1283). It was converted from a floating-point 
structured points set using vtkImageShiftScale, but that's about the 
only exotic thing about it.

Thanks in advance for any help,
Paul
