[vtkusers] Rendering scales on the order of the solar-system

I believe VTK can handle this but there are pitfalls if you want to have
huge distances combined with small scale local details. Basically create
two renderers on top of each other render the large scale first in one then
the small scale second on the other with SetTransparent(1). If your large
scale data goes in front of your small scale then it gets trickier as you
would need to use the zbuffer from the large scale as a texture with a
modified shader in the small scale. The details of which would not be a
short email.
