I will investigate making the application fail more gracefully. The
card seems to be conforming to what Intel stated - OpenGL 3.1. The VTK
code is rejecting it, so I guess it is not exposed or not available.
This is the on-die GPU with an i7 chip, it was working pretty well in
previous tests but I guess we tightened up the feature checking.
