AW: [vtkusers] "openGL error before vtkQGLRenderWindow::Render()"

[Carsten Kübler]

Hello Laurent,

I think you use my vtk-qt extension. In this case the error means that
the opengl context is in an error-state. The error occurs before the
execution of the render() method. I added these checks to detect opengl
errors in my application and in vtk.
