	* libnautilus-extensions/nautilus-art-extensions.h:
	* libnautilus-extensions/nautilus-art-extensions.c:
	(nautilus_art_irect_assign),
	Convenience function to assign x,y,width,height values to an
	ArtIRect.

	* libnautilus-extensions/nautilus-gdk-pixbuf-extensions.h:
	* libnautilus-extensions/nautilus-gdk-pixbuf-extensions.c:
	(nautilus_gdk_pixbuf_is_valid),
	A simple private function that returns whether a pixbuf is "valid"
	or not.  Vailidy is meassured as not null, with valid pixel data
	and non zero dimensions.

	(nautilus_gdk_pixbuf_get_frame),
	Private function to return the frame of a GdkPixbuf in a stucture for
	better readability.

	(nautilus_gdk_pixbuf_fill_rectangle_with_color),
	Changed it to use ArtIRect's instead of GdkRectangles to avoid
	using unsigned and short integers.  Also, use art_irect_interset()
	to do clipping.

	(nautilus_gdk_pixbuf_save_to_file),
	Changed the pixbuf parameter to be const.

	(nautilus_gdk_pixbuf_unref_if_not_null),

	(nautilus_gdk_window_get_frame),
	Private function to return the frame of a GdkWindow in a stucture for
	better readability.

	(nautilus_gdk_pixbuf_draw_to_drawable),
	Renamed function to be consitent with the other pixbuf drawing
	functions.  Also made it use ArtIRect's instead of GdkRectangles
	to avoid using unsigned and short integers.  Rewrote the clipping
	operations using art_irect_intersect() for better readability.

	(nautilus_gdk_pixbuf_draw_to_pixbuf),
	Renamed function to be consitent with the other pixbuf drawing
	functions.  Also made it use ArtIRect's instead of GdkRectangles
	to avoid using unsigned and short integers.  Rewrote the clipping
	operations using art_irect_intersect() for better readability.

	(nautilus_gdk_pixbuf_draw_to_pixbuf_alpha),
	Renamed function to be consitent with the other pixbuf drawing
	functions.  Also made it use ArtIRect's instead of GdkRectangles
	to avoid using unsigned and short integers.  Changed the
	implementation to honor all parameters including the source_x and
	source_y.  This is needed to work around limitation in
	gdk_pixbuf_composite().  Rewrote the clipping operations using
	art_irect_intersect() for better readability.

	(nautilus_gdk_pixbuf_new_from_pixbuf_sub_area),
	(pixbuf_destroy_callback),
	New function to create pixbuf from a sub area.  The pixel data is
	shared an all memory bookeeping is taken care of for the caller by
	simply unreffing the resulting pixbuf.

	(nautilus_gdk_pixbuf_draw_to_pixbuf_tiled),
	Renamed function to be consitent with the other pixbuf drawing
	functions.  Made the implementation work and honor all its
	parameters including the origin.   Rewrote the clipping
	operations using art_irect_intersect() for better readability.

	There was a bug (5077) about this function claiming it was not
	used except in test code.  This was true, but now that it works im
	planning on using it in NautilusImage shortly.  I have marked that
	bug fixed.

	(nautilus_gdk_pixbuf_show_in_eog):
	New function to show a pixbuf externally in eog.  Useful for
	debugging pixbuf stuff.

	* libnautilus-extensions/nautilus-buffered-widget.c:
	(nautilus_buffered_widget_draw), (nautilus_gdk_pixbuf_tile_alpha):
	Use new gdk-pixbuf extension functions.

	* libnautilus-extensions/nautilus-scalable-font.c:
	(nautilus_text_layout_paint):
	Update for changes in fill_rectangle_with_color() api.

	* src/nautilus-about.c: (nautilus_about_update_authors):
	Update for changes in fill_rectangle_with_color() api.

	* test/test-nautilus-font.c: (main):
	Update for changes in pixbuf extensions.
