	* gdk-pixbuf/gdk-pixbuf-animation.c
	(gdk_pixbuf_animation_new_from_file): same as below

	* gdk-pixbuf/io-gif.c (gif_get_lzw): added update of width and
	height in GdkPixbufAnimation

2000-03-28  Radek Doulik  <rodo@helixcode.com>

	* gdk-pixbuf/io-gif.c (gif_get_lzw): test also for
	context->frame_done_func and context->anim_done_func to make
	progressive animation loading work

	* gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
	added priv->pixbuf = NULL as pixbuf is now in frame (and to make
	gdk_pixbuf_loader_prepare happy)
	(gdk_pixbuf_loader_frame_done): update animation bbox

	* gdk-pixbuf/gdk-pixbuf.h: added bbox size (width, height) to
	_GdkPixbufAnimation

2000-03-27  Radek Doulik  <rodo@helixcode.com>

	* gdk-pixbuf/io-gif.c (gif_get_lzw): use frame_len and frame_width
	instead of width and height
