[Paraview] Re:Still Problem with Offscreen

[Clinton Stimpson]

The code you are referring to doesn't get called if you are using mangled
mesa.  And you're trying to use mangled mesa, right?

So perhaps it didn't get set properly to use mangled mesa at run time.  Any
one
else know how to make mangled mesa work in pvbatch?
