I am not a developer, just an list-observer, so I am afraid I am not
providing answers asked us.

Few points:

     1. Could you point us to the mentioned tool?
     2. I dunno what kind of bugs is your tool able to find but from my
        POV most security problems in the past came from old xpdf code
        and now from poppler lib. If you care in this area, probable
        focus there.
     3. How to get current Evince code is to be found here:

 4. The best way how to find out you how your tool interacts with
    Evince's code, actually, is to try it :).

Good luck.
