Subject: Create always a portrait cairo surface and rotate when needed for

2007-08-27  Carlos Garcia Campos  <carlosgc@gnome.org>
	* backend/pdf/ev-poppler.cc: (pdf_print_context_free),
	(pdf_document_file_exporter_begin),
	(pdf_document_file_exporter_do_page):
	* shell/ev-jobs.c: (ev_job_print_run):
	* shell/ev-window.c: (ev_window_print_dialog_response_cb):
	Create always a portrait cairo surface and rotate when needed for
	landscape. It fixes printing problems in real printers.
