Description

Implement digital signature support for PDF

This is a squash of the original branch

It also contains fixes/rework from Albert Astals Cid

If you're interested in its history have a look at the
gsoc2018_digitalsignature branch

The poppler dependency situation is:

  • With 0.51 you get most signature information
  • With 0.68 you also get signature location/reason information
  • With 0.73 you also get signature certificate information

Can you explain to me why you commented this? I'm running in some troubles with animated PDF that works as soon as I uncomment it.

One possible reason I could think of is the read-only nature of the signature form field. But I am not entirely sure because if it were unnecessary I'd have removed it. Can you tell me about your problem?

Strange! I checked my gsoc2018_digitalsignature branch and it was not commented there. Though it's totally possible that I made the change and forgot about it. Better ask Albert.
