Thanks for the reference.  However, this doesn't say "poppler does not
allow filling and saving PDF forms", it says "there is a bug in saving forms
with encrypted PDFs which is fixed in a later version of poppler."  It seems
like we should just get the poppler transition done (after confirming that
it fixes the problem), and be done with it?
