[Paraview] pvpython script fails on Paraview 5.0.1

[Cory Quammen]

It looks like you've built ParaView with the OpenGL backend while your
Windows binary is built against the OpenGL2 backend. These backends
have some disjoint properties exposed in ParaView, and the error you
are seeing is from a property in the state file generated from the
OpenGL2 backend that does not exist in the OpenGL backend. Hence the
error in your build

The easy solution is to delete the offending lines that contain
`SetScaleArray`. These lines just defines an array that adjusts some
property of the 3D Glyph representation in the OpenGL 2 backend. The
property would have not effect on your compiled ParaView anyway, so
you can just delete it.

Hope that clarifies things,
Cory
