It's not the podofo code causing problems, but poppler's code. But I
didn't take a closer look at that yet where the problem is exactly.
podofo is able to read and write annotations without problems (from what
I tried).

The next thing would be to support form contents to be saved and the
list could go on ...

So I'll just go on trying a bit, and next month there is even a chance
