	Hmm, I'm pretty confused as to what you are suggesting ... Are you

	* That we add a named icon[1] API that does nothing for now?

	* With every new non-named API we allow a name to be passed in which
will override the other icon data as soon as we have icon themeing? e.g.

void gtk_status_icon_set_from_pixbuf (GtkStatusIcon *status_icon,
                                      const char    *icon_name,
                                      GdkPixbuf     *pixbuf);

	so that when icon themeing is added to gtk+ that the pixbuf arg would
be ignored ?

	Maybe you're suggesting something else, but I don't think either of
these are preferable to just adding the named icon API once there is
icon themeing in gtk+.

Good Luck,

[1] - btw, when we see "named icon" we mean an icon name that you would
use to look up an icon according to the icon theme spec, right? Just to
be clear ...
