    	* gdk-pixbuf/gdk-pixbuf.h (GdkPixbufAnimation): Added reference
    	counting to animations.  A web browser may want to share a single
    	copy of an animated GIF if it appears multiple times in a web
    	page, for example.
    	* gdk-pixbuf/gdk-pixbuf-animation.c: New file.  Moved the
    	animation functions here.
    	(gdk_pixbuf_animation_new_from_file): Prettified.  Return a NULL
    	animation if the loader does not support multiframe loading and
    	the single-frame load returned NULL.  Check that the filename is
    	not NULL.  Updated inline documentation.
    	(gdk_pixbuf_animation_ref): New function.
    	(gdk_pixbuf_animation_unref): New function.
    	Removed gdk_pixbuf_animation_destroy() in favor of reference
    	* gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
    	Prettified.  Made ref_count assertion more paranoid.  Check that
    	the filename is not NULL.
    	(gdk_pixbuf_get_module): Use guchar * and guint for buffer and
    	size, respectively.
    	(gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
    	const char **.
    	* gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
    	with a reference count of 1.
    	* gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
    	* doc/tmpl/animation.sgml: Populated.  It is still missing a
    	description of the overlay modes.
    	* doc/gdk-pixbuf-sections.txt: Added the animation section.  Moved
    	the canvas item section to the end, as it will be moved later to
    	* doc/gdk-pixbuf.sgml: Added the animation section.
    	* doc/Makefile.am (tmpl_sources): Added tmpl/animation.sgml.
