Now I am a bit clueless on how I could create a link/dest pair.

If I understand things right: I have to create a pdf_dest node and find out its object number. Then I create a pdf_start_link/pdf_end_link pair with that object number for jumping to that place. 



Now: how do I know the object number? When I call tex.shipout(), the memory of that pdf_dest node is invalid (??), so I can't check anymore.
