[vtkusers] Output texture vertices in OBJ files?

[Berk Geveci]

I am not really familiar with the OBJ exporter but it looks like it
supports writing texture coordinates. Are you sure that the
input to the exporter has texture coords? It is possible that
one of the intermediate filters is not passing/generating texture
coords.
