Runs a page setup dialog, letting the user modify the values from
@page_setup. If the user cancels the dialog, the returned #GtkPageSetup
is identical to the passed in @page_setup, otherwise it contains the
modifications done in the dialog.
Note that this function may use a recursive mainloop to show the page
setup dialog. See gtk_print_run_page_setup_dialog_async() if this is
a problem.
