	The table menu patch! Turns GtkMenu into a table, so you can attach
	menu items in numerous new ways! Be creative!

	Contains some bug fixes and RTL adaptions from Matthias Clasen.

	* gtk/gtkmenu.c [toplevel]: introduce ATTACH_INFO_KEY, extend
	GtkMenuPrivate, introduce AttachInfo, add child properties enum,
	(gtk_menu_free_private), (gtk_menu_get_private): we have to free
	the heights array in the private struct,
	(gtk_menu_class_init): reorder code a bit, install child properties,
	(get_attach_info), (get_child_attach): new utility functions,
	(gtk_menu_set_child_property), (gtk_menu_get_child_property): introduce
	child properties, for the attach info,
	(gtk_menu_remove): remove AttachInfo from menu item,
	(gtk_menu_real_insert): implemented algorithm to automagically place
	inserted menu items at the correct place in the table,
	(gtk_menu_size_request), (gtk_menu_size_allocate),
	(compute_child_offset): reworked/rewritten to support table menus,
	(gtk_menu_attach): new function,
	(find_child_containing), (gtk_menu_move_current): new functions to
	get table menu keynav right.

	* gtk/gtkmenu.h: add gtk_menu_attach() prototype.
