Hi Kevin,

I would suggest you a submit a pull request to the SlicerVTK fork
backporting the functionality you would like. Then, when we will transition
to VTK6, it will go very smoothly.

In parallel, you could also submit a patch to the VTK list that would be
integrated to the VTK 5.10 maintenance branch.
