Subject: Use poppler instead of including xpdf source code. Poppler is a fork of

2005-03-01  Kristian Høgsberg  <krh@redhat.com>

        Use poppler instead of including xpdf source code.  Poppler is a
        fork of xpdf to build it as a shared library. See
        http://freedesktop.org/wiki/Software/poppler.

        * pdf/xpdf/*, pdf/goo/*, pdf/splash/*, pdf/fofi/*: Remove included
        xpdf fork.

        * pdf/Makefile.am: Build libpdfdocument.a here.

        * pdf/GDKSplashOutputDev.cc:
        * pdf/GDKSplashOutputDev.h:
        * pdf/GnomeVFSStream.cc:
        * pdf/GnomeVFSStream.h:
        * pdf-document.cc:
        * pdf-document.h:
        * test-gdk-output-dev.cc
        * Thumb.cc:
        * Thumb.h: Pull these files out of pdf/xpdf and adjust to compile
        against poppler.
