	From bgo 561139 (GdkPixbufSimpleAnim can't be made to loop)

	* gdk-pixbuf-simple-anim.c (gdk_pixbuf_simple_anim_class_init),
	(advance), (gdk_pixbuf_simple_anim_get_property),
	(gdk_pixbuf_simple_anim_set_property),
	(gdk_pixbuf_simple_anim_set_loop),
	(gdk_pixbuf_simple_anim_get_loop):
	* gdk-pixbuf-simple-anim.h:
	* gdk-pixbuf.symbols:

	Add a GdkPixbufSimpleAnim:loop property and its accessors, to allow a
	simple animation to loop forever. Based on a patch by Tim Evans.
