Soeren Sandmann eb3f5776ac delete this function (toolbar_item_is_homogeneous): cache 
Fri Oct 31 02:43:34 2003  Soeren Sandmann  <sandmann@daimi.au.dk>

	* gtk/gtktoolbar.c (get_item_requisition): delete this function
	(toolbar_item_is_homogeneous): cache max_homogeneous_pixels
	instead of re-calculating for each item.
	(gtk_toolbar_size_allocate): Update comments
