Raw Blame History

Fix compatibility with Poppler >= 0.69.
This is a combination of these upstream commits:
https://gitlab.com/inkscape/inkscape/commit/722e121361d0f784083d10e897155b7d4e44e515
https://gitlab.com/inkscape/inkscape/commit/402c0274420fe39fd2f3393bc7d8d8879d436358
...with slight adjustments for the 0.92.3 release tarball.
