[Paraview] Remote render / composite settings with MPI pvserver

[Sean Ziegeler]

Berk,
No trickery; I just turn off PARAVIEW_USE_ICE_T in CMake.  I am using 
cmake and not ccmake, so maybe that variable not exposed anymore in 
ccmake?  Anyway, my initial thought was to make things as simple as 
possible since AIX is less popular and PV is less tested than, say, on 
Linux.  I did some looking into it, and I think ICE-T is definitely the 
way to go, and it builds just fine.  Unfortunately, I get an entirely 
black screen when running.

I would say I could try running the ICE-T tests, but I'm not sure how, 
given that I'm building for MPI.  The system uses batch queues to submit 
MPI jobs.

Thanks,
Sean
