GtkPrintOperation is now able to render multiple pages per sheet by its own. The most important changes are in these functions: * increment_page_sequence * prepare_data * common_render_page * print_pages_idle Patch also changes set of choices for 2 pages per sheet mode when landscape orientation is used to "Top to bottom" and "Bottom to top".
