I've written some macros for just that purpose, though
they're still experimental and not yet fully finished. See my
homepage's WIP section, or some rather old images
I posted to the newsgroups.

Though they're not fully up to what you'd like, you
could perhaps use the source to learn from, at least
for placement etc.

Regards,
Tim
