OK, very nifty, this would almost certainly be the way to go for
embedding guppi into gtkhtml stuff.

Cool.  We probably *could* use that kind of thing to implement similar
functionality to what I'm busy doing with gtkpanes, but after thinking
about it I think panes will be better.  It's easier to provide a UI
for configurability and we can probably lay things out a little more
precisely.

If anybody wants to disagree, however, feel free, and feel free *right
now* before I do any more implementation :)

OK, the page splitting is working with the tarball the Helixcode guys
sent me (which may or may not be on anoncvs.gnome.org yet), but the
print preview seems to be borken (only one page is displayed with no
ability to switch between pages).  Can anyone else confirm this for
me?
