[Paraview] Paraview on SGI Altix 4000

[Moreland, Kenneth]

I mean the vendor-specific graphics driver provided by your system.  Often
we find render specific problems that are attributed to bugs in the system
graphics drivers, which are typically updated at a much faster rate than the
OpenGL or GLX standard changes.

When we see a graphics problem like this, it is hard to determine the actual
cause.  Thus, the first course of action is usually to update the vendor's
graphics driver to rule that out.  If the problem persists, then we look
elsewhere.
