Those functions haven't had any effect since mangled mesa stopped
working (I have never seen a working build), the classes were all
removed right after the branch for 5.10.

That function doesn't do anything, and has the same issue. I was
planning to remove vtkGraphicsFactory once I factored out the last bit
of code that requires it. I could leave a stub if you want, and get it
to manipulate the object factory overrides for off screen only mode
(which would not work on master, although it would compile).
