And that's the point here too -- releasing the library under the GPL
is an incentive for application developers (and other library
developers, FWIW) to release their work under the GPL.

I am not a GNU PDF maintainer/developer so my opinion is by definition
not authoritative, but I hope (and believe) that this library will
never be relicensed under a weak copyleft license such as LGPL.

(BTW, poppler is GPL too -- but sadly "v2 only", which is one of the
reasons of GNU PDF's inception.)

There is no problem to link an application (e.g. a PDF viewer) against
GNU PDF and Enlightenment libraries, provided that you release the
application under GPLv3.
