Do proper rounding of bounding box coordinates.

1999-11-03  Federico Mena Quintero  <federico@redhat.com>

	* src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
	rounding of bounding box coordinates.
	(gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
	(gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
