/**
 * A `GtkPageSetup` object stores the page size, orientation and margins.
 * 
 * The idea is that you can get one of these from the page setup dialog
 * and then pass it to the `GtkPrintOperation` when printing.
 * The benefit of splitting this out of the `GtkPrintSettings` is that
 * these affect the actual layout of the page, and thus need to be set
 * long before user prints.
 * 
 * ## Margins
 * 
 * The margins specified in this object are the “print margins”, i.e. the
 * parts of the page that the printer cannot print on. These are different
 * from the layout margins that a word processor uses; they are typically
 * used to determine the minimal size for the layout margins.
 * 
 * To obtain a `GtkPageSetup` use [ctor@Gtk.PageSetup.new] to get the defaults,
 * or use [func@Gtk.print_run_page_setup_dialog] to show the page setup dialog
 * and receive the resulting page setup.
 * 
 * ## A page setup dialog
 * 
 * ```c
 * static GtkPrintSettings *settings = NULL;
 * static GtkPageSetup *page_setup = NULL;
 * 
 * static void
 * do_page_setup (void)
 * {
 * GtkPageSetup *new_page_setup;
 * 
 * if (settings == NULL)
 * settings = gtk_print_settings_new ();
 * 
 * new_page_setup = gtk_print_run_page_setup_dialog (GTK_WINDOW (main_window),
 * page_setup, settings);
 * 
 * if (page_setup)
 * g_object_unref (page_setup);
 * 
 * page_setup = new_page_setup;
 * }
 * ```
