cleanup on the icon container, and I am checking in some of that
	before the stretching is implemented.

	* libnautilus/gnome-icon-container-private.h:
	* libnautilus/gnome-icon-container.c:
	(icon_is_in_region):
	Got rid of width and height stored in each icon.

	* libnautilus/gnome-icon-container.c:
	A lot of cleanup, including getting rid of the
	icon_get_text_bounding_box function.

	* libnautilus/gnome-icon-container.c:
	(gnome_icon_container_begin_stretch):
	(gnome_icon_container_stretch):
	(gnome_icon_container_end_stretch):
	(button_release_event):
	(motion_notify_event):
	(handle_icon_button_press):
	First cut at adding stretching hooks in button handlers.

	* libnautilus/nautilus-icons-view-icon-item.c:
	(nautilus_icons_view_draw_text_box):
	Rewrote to fix bug with position of text when it's too long for
	a single line.

	* libnautilus/nautilus-glib-extensions.h:
	Added a macro named NAUTILUS_G_N_ELEMENTS.
	src/ntl-index-panel.c:
	src/explorer-location-bar.c:
	libnautilus/gtkflist.c:
	Used the NAUTILUS_G_N_ELEMENTS macro.
