	Add a GrabBroken event to GDK, and a grab-broken-event
	signal to GtkWidget.  (#107320, Simon Cooke, initial patch
	by John Ehresman)

	* gdk/gdkevents.h: Add a GDK_GRAB_BROKEN event type,
	define a GdkEventGrabBroken event struct.

	* gdk/win32/gdkevents-win32.c (gdk_event_translate):
	Generate GrabBroken events in response to WM_KILLFOCUS.

	* gdk/x11/gdkmain-x11.c: Generate GrabBroken events
	when a grab is broken by the window becoming unviewable,
	or by another grab from the same client.

	* gtk/gtkwidget.h (GtkWidgetClass): Add grab_broken_event.

	* gtk/gtkwidget.c (gtk_widget_event_internal): Translate
	GrabBroken events into grab_broken_event signals.

	* gtk/gtkmain.c (gtk_main_do_event): Propagate GrabBroken
	events.

	* gtk/gtkmenushell.c (gtk_menu_shell_grab_broken): Deactivate
	the menu when the grab is broken.

	* gtk/gtkcolorsel.c (gtk_color_selection_grab_broken): Stop
	the color picker if the grab is broken.

	* gtk/gtkpaned.c (gtk_paned_grab_broken): Stop the drag if
	the grab is broken.
