/** A PageSetup object stores the page size, orientation and margins. You can get one of these from the page setup dialog
 * and then pass it to the PrintOperation when printing. The benefit of splitting this out of the PrintSettings is that
 * these affect the actual layout of the page, and thus need to be set long before the user prints.
 *
 * 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 PageSetup use PageSetup::create() to get the defaults, or use run_page_setup_dialog() to show the page
 * setup dialog and receive the resulting page setup.
