[vtk-developers] VTK_MAJOR_VERSION is no longer #define'ed

[Bill Lorensen]

I really do not want to turn VTK_LEGACY_REMOVE OFF. If enables much
more than the new versioning.

In the hundreds of examples I have converted to work with both VTK5
and VTK6 I've used this pattern:
#if VTK_MAJOR_VERSION <= 5
  inputMapper->SetInput(inputPolyData);
#else
  inputMapper->SetInputData(inputPolyData);
#endif

I would like this code to work without having to add another #include.
