[Paraview] client/server error for large superquadrics

Wayne,

Super duper!

Okay now that we got the problem figured out... read Ken's email on how
to fix the problem... :)

You really should have large data rendered on the server side (that's
the whole point of the parallel rendering that people put lots of work
into...)

Otherwise, as you said, large data will be rendered very slowly... :)
