Subject: Separate scan and fill so that we can incrementally fill from the main

2005-06-13  Marco Pesenti Gritti <mpg@redhat.com>

        * backend/ev-document-fonts.c: (ev_document_fonts_get_progress),
        (ev_document_fonts_scan), (ev_document_fonts_fill_model):
        * backend/ev-document-fonts.h:

        Separate scan and fill so that we can incrementally fill from
        the main thread. Add a progress api.

        * data/evince-properties.glade:
        * pdf/ev-poppler.cc:
        * shell/ev-jobs.c: (ev_job_fonts_new), (ev_job_fonts_run):
        * shell/ev-jobs.h:
        * shell/ev-properties.c: (update_progress_label),
        (job_fonts_finished_cb), (setup_fonts_view):

        Incrementally feel the list and show the progress
        percentage in a label like acrobat does.
