[vtkusers] can't write obj files

[Gabriele Fanelli]

HI David,

I see, there is no actual implementation of vtkOBJWriter, I should have 
noticed that. But as you say, obj is a pretty common format so it would 
be nice to have the possibility to write such files.

Thanks for the help, I eventually managed to make things work with your 
code and compiling vtk as shared libraries.
I still don't know why it did not work when compiled statically, but as 
long as it works now I am happy :).

Cheers,
Gabriele
