-/**
- * GtkPageSetup:
- *
- * 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;
- * }
- * ```

- * GtkPrintContext:
- *
- * A `GtkPrintContext` encapsulates context information that is required when
- * drawing pages for printing.
- *
- * This includes the cairo context and important parameters like page size
- * and resolution. It also lets you easily create [class@Pango.Layout] and
- * [class@Pango.Context] objects that match the font metrics of the cairo surface.
- *
- * `GtkPrintContext` objects get passed to the
- * [signal@Gtk.PrintOperation::begin-print],
- * [signal@Gtk.PrintOperation::end-print],
- * [signal@Gtk.PrintOperation::request-page-setup] and
- * [signal@Gtk.PrintOperation::draw-page] signals on the
- * [class@Gtk.PrintOperation] object.

-/**
- * GtkPrintOperation:
- *
- * `GtkPrintOperation` is the high-level, portable printing API.
- *
- * It looks a bit different than other GTK dialogs such as the
- * `GtkFileChooser`, since some platforms don’t expose enough
- * infrastructure to implement a good print dialog. On such
- * platforms, `GtkPrintOperation` uses the native print dialog.
- * On platforms which do not provide a native print dialog, GTK
- * uses its own, see [class@Gtk.PrintUnixDialog].
- *
- * The typical way to use the high-level printing API is to create
- * a `GtkPrintOperation` object with [ctor@Gtk.PrintOperation.new]
- * when the user selects to print. Then you set some properties on it,
- * e.g. the page size, any [class@Gtk.PrintSettings] from previous print
- * operations, the number of pages, the current page, etc.
- *
- * Then you start the print operation by calling [method@Gtk.PrintOperation.run].
- * It will then show a dialog, let the user select a printer and options.
- * When the user finished the dialog, various signals will be emitted on
- * the `GtkPrintOperation`, the main one being
- * [signal@Gtk.PrintOperation::draw-page], which you are supposed to handle
- * and render the page on the provided [class@Gtk.PrintContext] using Cairo.
- *
- * # The high-level printing API
- *
- * ```c
- * static GtkPrintSettings *settings = NULL;
- *
- * static void
- * do_print (void)
- * {
- * GtkPrintOperation *print;
- * GtkPrintOperationResult res;
- *
- * print = gtk_print_operation_new ();
- *
- * if (settings != NULL)
- * gtk_print_operation_set_print_settings (print, settings);
- *
- * g_signal_connect (print, "begin_print", G_CALLBACK (begin_print), NULL);
- * g_signal_connect (print, "draw_page", G_CALLBACK (draw_page), NULL);
- *
- * res = gtk_print_operation_run (print, GTK_PRINT_OPERATION_ACTION_PRINT_DIALOG,
- * GTK_WINDOW (main_window), NULL);
- *
- * if (res == GTK_PRINT_OPERATION_RESULT_APPLY)
- * {
- * if (settings != NULL)
- * g_object_unref (settings);
- * settings = g_object_ref (gtk_print_operation_get_print_settings (print));
- * }
- *
- * g_object_unref (print);
- * }
- * ```
- *
- * By default `GtkPrintOperation` uses an external application to do
- * print preview. To implement a custom print preview, an application
- * must connect to the preview signal. The functions
- * [method@Gtk.PrintOperationPreview.render_page],
- * [method@Gtk.PrintOperationPreview.end_preview] and
- * [method@Gtk.PrintOperationPreview.is_selected]
- * are useful when implementing a print preview.

+ * GtkPageSetup:
+ *
+ * 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)

+ * GtkPrintContext:
+ *
+ * A `GtkPrintContext` encapsulates context information that is required when
+ * drawing pages for printing.
+ *
+ * This includes the cairo context and important parameters like page size
+ * and resolution. It also lets you easily create [class@Pango.Layout] and
+ * [class@Pango.Context] objects that match the font metrics of the cairo surface.
+ *
+ * `GtkPrintContext` objects get passed to the
+ * [signal@Gtk.PrintOperation::begin-print],
+ * [signal@Gtk.PrintOperation::end-print],
+ * [signal@Gtk.PrintOperation::request-page-setup] and
+ * [signal@Gtk.PrintOperation::draw-page] signals on the
+ * [class@Gtk.PrintOperation] object.

+/**
+ * GtkPrintOperation:
+ *
+ * `GtkPrintOperation` is the high-level, portable printing API.
+ *
+ * It looks a bit different than other GTK dialogs such as the
+ * `GtkFileChooser`, since some platforms don’t expose enough
+ * infrastructure to implement a good print dialog. On such
+ * platforms, `GtkPrintOperation` uses the native print dialog.
+ * On platforms which do not provide a native print dialog, GTK
+ * uses its own, see [class@Gtk.PrintUnixDialog].
+ *
+ * The typical way to use the high-level printing API is to create
+ * a `GtkPrintOperation` object with [ctor@Gtk.PrintOperation.new]
+ * when the user selects to print. Then you set some properties on it,
+ * e.g. the page size, any [class@Gtk.PrintSettings] from previous print
+ * operations, the number of pages, the current page, etc.
+ *
+ * Then you start the print operation by calling [method@Gtk.PrintOperation.run].
+ * It will then show a dialog, let the user select a printer and options.
+ * When the user finished the dialog, various signals will be emitted on
+ * the `GtkPrintOperation`, the main one being
+ * [signal@Gtk.PrintOperation::draw-page], which you are supposed to handle
+ * and render the page on the provided [class@Gtk.PrintContext] using Cairo.
+ *
+ * # The high-level printing API
+ *
+ * ```c
+ * static GtkPrintSettings *settings = NULL;
+ *
+ * static void
+ * do_print (void)
+ * {
+ * GtkPrintOperation *print;
+ * GtkPrintOperationResult res;
+ *
+ * print = gtk_print_operation_new ();
+ *
+ * if (settings != NULL)
+ * gtk_print_operation_set_print_settings (print, settings);
+ *
+ * g_signal_connect (print, "begin_print", G_CALLBACK (begin_print), NULL);
+ * g_signal_connect (print, "draw_page", G_CALLBACK (draw_page), NULL);
+ *
+ * res = gtk_print_operation_run (print, GTK_PRINT_OPERATION_ACTION_PRINT_DIALOG,
+ * GTK_WINDOW (main_window), NULL);
+ *
+ * if (res == GTK_PRINT_OPERATION_RESULT_APPLY)
+ * {
+ * if (settings != NULL)
+ * g_object_unref (settings);
+ * settings = g_object_ref (gtk_print_operation_get_print_settings (print));
+ * }
+ *
+ * g_object_unref (print);
+ * }
+ * ```
+ *
+ * By default `GtkPrintOperation` uses an external application to do
+ * print preview. To implement a custom print preview, an application
+ * must connect to the preview signal. The functions
+ * [method@Gtk.PrintOperationPreview.render_page],
+ * [method@Gtk.PrintOperationPreview.end_preview] and
+ * [method@Gtk.PrintOperationPreview.is_selected]
+ * are useful when implementing a print preview.
