Update spec.

2005-03-15  Anders Carlsson  <andersca@imendio.com>

	* docs/iconcache.txt:
	Update spec.

	* gtk/gtkiconcache.c: (find_image_offset),
	(_gtk_icon_cache_get_icon_flags), (_gtk_icon_cache_add_icons),
	(_gtk_icon_cache_get_icon), (_gtk_icon_cache_get_icon_data):
	* gtk/gtkiconcache.h:
	Update to be able to fetch pixbuf data and icon metadata.

	* gtk/gtkicontheme.c: (theme_lookup_icon), (gtk_icon_info_free),
	(icon_info_ensure_scale_and_pixbuf):
	Use new cache functions.

	* gtk/updateiconcache.c: (foreach_remove_func), (load_icon_data),
	(maybe_cache_image_data), (scan_directory), (write_pixdata),
	(get_image_meta_data_size), (get_image_pixel_data_size),
	(get_image_data_size), (get_single_node_size), (get_bucket_size),
	(write_bucket), (main):
	Update to write pixbuf data as well as information from .icon
	files.
