    	Rework sliding algorithm.
    	- No more weird jumping when items are dragged off and added to
    	the toolbar,
    	- More natural item movement
    
    	* gtk/gtktoolbar.c (gtk_toolbar_size_allocate): Many changes. This
    	function is now responsible for calculating intermediate positions
    	during item sliding. It is also responsible for starting sliding
    	if items disappear.  Also turn off expanding when there is an
    	overflow menu.
    	(gtk_toolbar_begin_sliding, stop_sliding): New functions.
    	(slide_idle_handler): New function. All the sliding is now done by
    	gtk_toolbar_size_allocate(), so the idle handler now just checks
    	if there is more sliding to be done.
    	(compute_intermediate_allocation, position): new functions
    	calculating intermediate steps in the slide animations. The new
    	animation algorithm uses a constant speed instead of a constant
    	must-be-finished-within time.
    	(struct _ToolbarContent): use
    	GtkAllocation goal_allocation; and
    	GtkAllocation start_allocation; instead of
    	gint start/goal_width;
    
    	* gtk/gtktoolitem.c (gtk_tool_item_set_tooltip): fix typo in
    	documentation
