I can't say I'm too surprised. Most of the work I've done on podofo has
been fixups and cleanups, and there's plenty more to do. I find the
annotation code particularly unclear.
A test case or two illustrating the problem wouldn't hurt, though.

It's not as bad as it sounds. PDF is designed to be appendable, so you
can potentially get away with appending annotations without disturbing
the main document, something that would probably permit a simpler
approach to writing the appended PDF data. This also, handily, preserves
digital signatures. The downside is that people will want to be able to
change more and more, and poppler really isn't designed to be usable as
a PDF editing library.
