Awesome, thank you very much, I wasn't aware of this :)

Last time some people tried to backport some of your patches
(admittedly to TeX Live 2018) and eventually gave up, but it could be
that LuaTeX was the main blocker (which will no longer be the case in
TL 2019 anyway). I didn't look into it at that time, we simply
switched to the built-in version. I'll retry with the latest sources.

Thank you again,

(I hope that at some point someone will be able to migrate from
poppler to pplib also for XeTeX and pdfTeX :)
