2005-06-14  Marco Pesenti Gritti <mpg@redhat.com>

        * backend/ev-document.c: (ev_document_set_orientation):
        * backend/ev-document.h:
        * pdf/ev-poppler.cc:

        Add orientation api. Currently poppler api is not optimal,
        we need to set orientation every time we _get a page

        * data/evince-ui.xml:
        * shell/ev-window.c: (ev_window_cmd_edit_landscape),
        (ev_window_cmd_edit_portrait), (ev_window_cmd_edit_flip):

        Add orientation menu items

        * shell/ev-page-cache.c: (ev_page_cache_clear):
        * shell/ev-page-cache.h:

        Add api to clear the cache

        * shell/ev-view.c: (setup_caches), (clear_caches),
        (ev_view_set_document), (ev_view_zoom_out),
        (ev_view_set_orientation):
        * shell/ev-view.h:

        Implement orientation changing
