Summary0014805: QVTKGraphicsItem does not call OpenGLInitContext() on its render window
DescriptionThe vtkGenericOpenGLRenderWindow does not call OpenGLInit() by itself (in contrast to vtkWin32/X/.../RenderWindows. The OpenGLInit() calls OpenGLInitContext(), which initializes the GL Extension manager and the vtkgl entry points.

When rendering a scene using the QVTKGraphicsItem which uses entry points of vtkgl, this crashes because OpenGLInitContext() was never called.

The problem goes away if one uses a QVTKWidget/QVTKWidget2 first, because this initialized the global vtkgl entry points.

I think it would be better to call OpenGLInitContext() on the render window in QVTKGraphicsItem::MakeCurrent() when MakeCurrent is called the first time.
