As I understand what you want is apps no longer "embedding" "real" widgets on 
top of the forms but the apps drawing the forms themselves based on info given 
by poppler?

I am not sure this is going to be easy to do, since using "real" widgets gives 
you lots of functionality for free (e.g: copy/paste, keyboard/mouse handling, 
etc) and if we do what you say I understand we have to stop using "real" 
widgets and do all this stuff in the final app which will be lots of work. Of 
course that does not mean that we could still provide the option to have it 
and not make it mandatory.

Or did I totally misunderstand what you meant?
