* backend/ev-document.c: (ev_document_base_init),
(ev_document_changed):
* backend/ev-document.h:
Add a changed event that is emitted when the page content
changes. This is necessary to deal with the fact that
in ps backend rendering happen asycrounously.
This makes the ps backend mostly work.
* pdf/xpdf/pdf-document.cc:
Emit changed event
* ps/gtkgs.c: (set_up_page), (gtk_gs_widget_event),
(ps_document_set_target):
Emit changed event
* shell/ev-view.c: (document_changed_callback),
(ev_view_set_document), (ev_view_set_page):
Redraw on the changed signal
