[vtk-developers] Rendering of vtkPolyData broken on Nvidia systems

[Cory Quammen]

Sigh. Nothing like removing useful features from a widely used API for
no good (in my mind) reason.

This page has information about the ARB_compatibility extension as
implemented by NVIDIA:

http://developer.nvidia.com/opengl-driver

Perhaps VTK needs to load this extension to maintain the use of display lists?
