take frame offest into account when trying to calculate the animation

2000-06-06  Larry Ewing  <lewing@helixcode.com>

	* gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
	take frame offest into account when trying to calculate the
	animation bbox.  Also set the width to the width not the height.
	(gdk_pixbuf_loader_frame_done): cycle over the frames to calculate
	bbox since only now do we have all the offset information for each
	frame.
