[Paraview] How to do volume rendering of image data?

[Steve Huntley]

Up to now I have been working with version 3.2.  I just installed 
version 3.8 to see if there were any differences in behavior.

In version 3.8 I'm not allowed to do volume rendering at all.  When I 
try to set the "Volume" representation option (which resulted in display 
of a black block in 3.2), I now get an error message that says "Cannot 
volume render since no point (or cell) data available."

Has the volume-rendering-of-image-data feature been excised from version 
3.8?
