Subject: Change api to lookup from uri. Do fast lookup first, if the type is

2005-05-08  Marco Pesenti Gritti  <mpg@redhat.com>

        * shell/ev-document-types.c: (get_slow_mime_type),
        (get_document_type_from_mime), (ev_document_type_lookup):
        * shell/ev-document-types.h:

        Change api to lookup from uri. Do fast lookup first, if the
        type is unknown try with data sniffing.

        * shell/ev-window.c: (ev_window_open), (ev_window_open_uri_list):
        * thumbnailer/evince-thumbnailer.c: (evince_thumbnail_pngenc_get):

        Adapt to api change
