Jonathan Blandford 82c5ace889 get logic right, #66249 
Fri Dec  7 20:06:14 2001  Jonathan Blandford  <jrb@redhat.com>

	* gtk/gtktreeview.c (validate_visible_area): get logic right,
	#66249

	* gtk/gtkrbtree.c (_gtk_rbtree_remove_node): fix bug where
	removing a node ended up with a corrupt tree.  Really really nasty
	bug.
	(_gtk_rbtree_debug_spew): new debug helper function
	(_fixup_validation): new inline function to clean up code
	readability a lot.
