New file with some random thoughts.

        * NOTES: New file with some random thoughts.

        * TODO: Update.

        * backend/ev-document-misc.c:
        (ev_document_misc_get_page_border_size): New function to
        canonicalize shadow drawing sizes.  Possibly goofy.

        * shell/ev-view.c: (ev_view_size_request), (set_document_page),
        (ev_view_best_fit), (ev_view_fit_width):
        * pdf/xpdf/pdf-document.cc:
        * pixbuf/pixbuf-document.c: (pixbuf_document_get_page_size):
        * ps/ps-document.c: (ps_document_get_page_size):
        * backend/ev-document-misc.h:
        * backend/ev-document.c: (ev_document_get_page_size):
        * backend/ev-document.h: get_page_size now takes a page number
        parameter.  Made all the backends/frontends honor it.

        * data/evince-ui.xml: Added a multiple-page mode.  Uncomment to
        see.  Doesn't work yet.

        * shell/Makefile.am:
        * shell/ev-page-view.[ch]: New multi-page view.  Really rough.
        Doesn't do anything yet.

        * shell/ev-sidebar-thumbnails.c:
        (ev_sidebar_thumbnails_set_document): [1..n_pages] instead of
        [0..n_pages-1]

        * shell/ev-window.c: (update_action_sensitivity),
        (ev_window_setup_document), (ev_window_set_page_mode),
        (ev_window_page_mode_cb), (ev_window_init): Clean up the
        view-swapping code a bit so we can have multiple views on a
        document.  Add the multi-page view, though it can't be turned on
        yet.

+SOME RANDOM COMMENTS:
+=====================
+
+ * We assume that all documents can be broken down into a linear
+   collection of pages.
+
+ * If a document type doesn't break down in such a way (like web pages)
+   then it's probably not a good fit for this application.
+
+ * Each page has a natural page size in pixels.  This is generally
+   ignored in favor of a scale-to-fit mode, but is occasionally
+   important for backends like the image backend.
+
+ * Each page is not necessarily the same size.
+
+ * We refer to pages by page number.  This number ranges from 1 to
+   document->n_pages.  A page index of -1 means the current set page,
+   and a page index of 0 is not used.

+
+Thoughts on threading:
+
+ * The primary thing we are trying to do is minimize switching pages, as
+   doing so is slow for backends.  Additionally, some operations on the
+   backend are slow, leaving poor interactivity.  This
