[vtkusers] vtk-7.1 openGL 2.0 crash

[satwik k]

Is thr any way to find out OpenGL version in VTK .
 So that system which supports OpenGL 2.0 can make use of VTK 7.0 OpenGL
2.0 as Rendering backed.

System which won't support OpenGL 2.0 can make use of OpenGL as Rendering
backend.



Regards,
Satwik k
