shipout is somewhat special and we don't have a callback for the shipout 

in a regular macro package, the page is packaged in a box (often 255 ) 
and you can hook in some lua code there:

- locate the \shipout command being used
- see what box is shipped out
- do a directlua just before \shipout and look the box

so, something:


(there will be a callback for this but it's not an isolated event as for 
instance xforms are also shipped out and the xform subsystem is not 
opened up / redone yet)
