	* docs/Changes-2.0.txt: Add note about GtkMenuPositionFunc
	API changes.

	* gtk/gtkmenu.c: Add support for scrolling menus.
	Remove gtk_menu_append/prepend/insert, these have been moved to
	gtkcompat.h as #defines.

	* gtk/gtkcompat.h.in:
	Add compatibility #defines for gtk_menu_append/prepend/insert

	* gtk/gtkmenu.h: Add data needed for scrolling menus.
	GtkMenuPositionFunc gets an extra argument push_in.
	gtk_menu_append/prepend/insert removed.

	* gtk/gtkmenuitem.c (gtk_menu_item_position_menu): Change menu
	positioning behaviour to fit to scrolling menus.

	* gtk/gtkmenuitem.c (gtk_menu_item_forall): Don't recurse
	into menuitem->submeny. That is wrong, and broke torn
	off submenus of torn off menus, since they were unrealized
	when the first menu was unrealized.

	* gtk/gtkmenushell.[ch]: Virtualize gtk_menu_shell_insert() and
	gtk_menu_shell_select_item() since these need to be overridden in
	GtkMenu.

	* gtk/gtkoptionmenu.c (gtk_opttion_menu_position): Change menu
	positioning behaviour to fit to scrolling menus.
	(gtk_option_menu_key_press, gtk_option_menu_button_press): Select
	the current item so that it is prelighted when the menu pops up.
	This is a workaround to the fact that the menu doesn't get the
	initial enter event (due to grabs).

	* gtk/gtkfilesel.c, gtk/gtkinputdialog.c, gtk/testgtk.c:
	s/gtk_menu_append/gtk_menu_shell_append/

	* gtk/gtknotebook.c:
	s/gtk_menu_insert/gtk_menu_shell_insert/

	* gtk/testgtk.c (create_menu, create_menus):
	Create the first menu with 50 items so that menu scrolling
	can be tested.

	Patch from Jonathan Blandford  <jrb@redhat.com>

	* gtk/gtkmenuitem.[ch] (gtk_menu_item_toggle_size_request): new
	system to handle size requests.  First, we ask what the size of
	the toggle is.  Then, when allocating the size, we allocate the
	toggle_size first.  This way we can have multiple menu-item
	classes w/o needing a seperate class for each.

	* gtk/gtkmenu.c (gtk_menu_size_request): Actually use the new system.
	* gtk/gtkmenu.c (gtk_menu_size_allocate): Use the new system.

	* gtk/gtkcheckmenuitem.c
	(gtk_check_menu_item_toggle_size_request): New function to handle
	the toggle size-request.
