[vtkusers] GL2PSExporter

[David Lonie]

I don't see anything there that would cause a problem. Can you report this
as a bug on the VTK bug tracker?

https://gitlab.kitware.com/vtk/vtk/issues

I'm not sure we'll be able to fix this unless we have a developer who can
reproduce it, but it'll be good to have a record of this.

As a work-around, maybe try out some different OpenGL drivers
(nvidia/ati/intel vs. mesa, etc). It might be a driver issue.
