I did not have time to finish the poppler work and even if this will probably be good for using the poppler work, this adds new API and I don't want to commit to this since having a proper look at making it work
Sorry i failed to fulfill my promise
For now it's disabled, as I want to investigate a bit more with poppler wrt text fields, and to verify if that is an acceptable behaviour.
