	* libgimpwidgets/gimpdialog.c: implement GtkDialog::close() and
	synthesize a "delete_event" unconditionally.

	* app/widgets/gimpviewabledialog.c: emit "close" instead of
	synthesizing "delete_event".

	* app/widgets/gimppreview.[ch]: removed "extended_clicked" signal
	and added "GdkModifierType state" to "clicked"'s signature.

	* app/gui/file-open-dialog.c
	* app/gui/test-commands.c
	* app/widgets/gimpcontainergridview.c
	* app/widgets/gimptoolbox-indicator-area.c: changed accordingly.
