[vtkusers] Offscreen rendering (6.2.0+ OpenGL2 backend), empty image depending on interactor

[Paul Melis]

Hi,

First off, the new OpenGL2 backend is great, keep up the good work!

The attached offscreen rendering test produces an empty image when using 
the generic render window interactor, with the regular window interactor 
the saved image is correct. This only seems to happen for 6.2.0 when 
using the OpenGL2 backend.

Does the generic RWI need some kind of extra initialization?

Regards,
Paul
