Removed the x_set and y_set arguments. Now they are always on and start

2000-01-22  Federico Mena Quintero  <federico@helixcode.com>

	* gdk-pixbuf/gnome-canvas-pixbuf.c (PixbufPrivate): Removed the
	x_set and y_set arguments.  Now they are always on and start with
	defaults of 0.0 in units.
	(gnome_canvas_pixbuf_class_init): Likewise.
	(gnome_canvas_pixbuf_set_arg): Likewise.
	(gnome_canvas_pixbuf_get_arg): Likewise.
	(compute_viewport_affine): Likewise; always use the priv->x and
	priv->y fields.

	* doc/tmpl/gnome-canvas-pixbuf.sgml: Modified to reflect the
	removal of the x_set/y_set arguments.
