[vtkusers] vtkShaderProgram error :extension 'GL_EXT_gpu_Shader4' not supported VTK 7.0.0

[Mallikarjun K]

Hi Chiang,
Thanks for the response.
With the same integrated gpu, vtk 6.1 gpuMapper doesn't complain like
this.As vtk 7 is by default using opengl2 backend,I think I have missed
something here.I updated my graphics drivers too.Still no luck..

With Kind Regards,
Mallikarjun
