Subject: Move ev_view_update_view_size() from libview to ev-window again and make

2009-04-06  Carlos Garcia Campos  <carlosgc@gnome.org>

	* libview/ev-view.[ch]: (ev_view_set_zoom),
	(ev_view_update_view_size):
	* shell/ev-window.c: (ev_window_set_view_size),
	(ev_window_sizing_mode_changed_cb), (ev_window_init):

	Move ev_view_update_view_size() from libview to ev-window again
	and make sure the view is not redrawn when calling
	ev_view_set_zoom more than once with the same zoom scale.
