	Improve progressive loading from slow sources:  (#107368)

	* io-gif-animation.c (gdk_pixbuf_gif_anim_get_iter): Initialize
	first_loop_slowness.
	(gdk_pixbuf_gif_anim_iter_advance): Don't wrap during loading if
	the datasource falls behind the speed of the display.

	* io-gif-animation.h: Add a loading flag to GdkPixbufGifAnim and
	first_loop_slowness to GdkPixbufGifAnimIter.
