Havoc Pennington 9cca191b6a Fix bugs Alex found: 
2000-12-04  Havoc Pennington  <hp@redhat.com>

        Fix bugs Alex found:

	* gtk/gtktooltips.c (gtk_tooltips_force_window): nuke connection
	to "draw"

	* gtk/gtkdnd.c (gtk_drag_highlight): nuke connection to "draw"

	* gtk/gtkcolorsel.c (palette_new): nuke connection to "draw"

	* gtk/gtklistitem.c (gtk_list_item_expose): Put the old _draw()
	implementation in here, apparently the expose() implementation was
	dead code.
