[luatex] DVI h/vlist position

[Linas]

Hi, All!
I tried to find an info about (h/v)list coordinates in dvi file. Is it possible
to find out any corner of hlist where it is fitted into a page?

There could be an information reporting callback 'shipout_filter' which could
write a positions of the fitted boxes?

shipout: hbox atrr lly llx width height 
(width and height is known from hlist node)

does anybody knows about box coordinates after shipout?

thanks, Linas
