[vtkusers] Remote Desktop and the VTK window

[David E DeMarle]

Besides the above options, software mesa gl can work.

You can build or more simply grab dlls from
https://github.com/pal1000/mesa-dist-win, put the dll's into place, set an
environment variable or two, and then the VTK app will bypass the system
opengl and the gpu. Rendering is unlikely to be fast though.
