[vtkusers] Error: no override found for 'vtkRayCastImageDisplayHelper'

[Yassmin Abdallah]

No sir you are right, 

just added this line and it works fine,

    vtkObjectFactory::RegisterFactory(vtkRenderingOpenGL2ObjectFactory::New());
    
    vtkObjectFactory::RegisterFactory(vtkRenderingVolumeOpenGL2ObjectFactory::New());

Thanks a lot.
