[vtkusers] Sharing 3D textures on GPU between multiple openGL contexts

[Zein Salah]

Hi everybody,

I have a 3D texture (i.e., a 3D image volume) on the GPU that I want to share
between multiple contexts. In essence, I want to display different views of the
same texture in different widgets using different shader/fragement programs.

1. Is this possible in VTK?
2. Which version of VTK supports this?

Much thanks,
Zein
