Base the decision to map/unmap items on whether they are actually

	* gtk/gtktoolbar.c (gtk_toolbar_size_allocate): Base the decision
	to map/unmap items on whether they are actually allocated outside
	the toolbar, not on whether that will eventually happen. Improves
	animation in the presence of overflown items.

	* gtk/gtktoolbar.c (gtk_toolbar_begin_sliding): Add a
	queue_resize() to so that the items will get their new goal
	values and the idle handler will not immediately return FALSE.

	* gtk/gtktoolbar.c (slide_idle_handler): simplify the logic and
	make sure that a placeholder becoming invisible doesn't cause a
	return TRUE.

	* gtk/gtktoolbar.c (get_item_size): Don't special case
	placeholders here.
