[vtkusers] VTK 7 and vtkRenderingOpenGL2 migration

[Orion Poplawski]

I'm looking at updating the Fedora VTK package to 7.0 and rebuilding dependent
packages here: https://copr.fedorainfracloud.org/coprs/orion/vtk7/builds/

One problem is packages (e.g. engrid) that do:

VTK_MODULE_INIT(vtkRenderingOpenGL);

It appears that with VTK 7.0 it would need to do:

VTK_MODULE_INIT(vtkRenderingOpenGL2);

What's the best way for projects to handle this automatically, as the vtk they
are building against may have been built with either backend.
