I love the idea to integrate this with hippo, though I think it would be
better to keep the poppler bindings as a separate project and have
HippoPDF depend on this. Not trivial auto* magics would be necessary to
keep it inside hippo anyway, because we can't enable it unconditionally
(mugshot can't depend on it).

I can hack a basic poppler-python package for you with the build stuff
later tonight (or at worst tomorrow morning). We could use a git repo on
dev.laptop.org for it...
