[vtkusers] Offscreen Rendering under Windows?

[Aaron Linnen]

A quick question before I spend too much time on it... is offscreen 
rendering possible under windows? I know that Mesa does (supposedly!) 
work under win32 and have seen the instructions here 
http://public.kitware.com/cgi-bin/vtkfaq?req=show&file=faq05.015.htp

For this project, speed is not a primary concern, but both having it run 
reliably and without driver issues on a wide variety of hardware and 
have the excact same output are key.

Has anyone tried this or have any advice?

Thanks,
Aaron
