[vtk-developers] Wrapping vtkConfigure.h, vtkType.h, etc.

[Dave Partyka]

Hey David,

Can you look at the ParaView dashboard? I think some of these changes are
causing build errors with client server wrapping.

/home/kitware/dashboards/paraview-build-all-debug/Utilities/VTKClientServer/Common/vtkCommandClientServer.cxx:
In function ‘int vtkCommandCommand(vtkClientServerInterpreter*,
vtkObjectBase*, const char*, const vtkClientServerStream&,
vtkClientServerStream&)’:
/home/kitware/dashboards/paraview-build-all-debug/Utilities/VTKClientServer/Common/vtkCommandClientServer.cxx:14:20:
error: ‘SafeDownCast’ is not a member of ‘vtkCommand’
