Depends for what purposes.  The fringes generally take less space for
small enough images, and "other editors" provide similar features,
including for breakpoint markers.

My point is that if some Lisp program needs to display something
larger and more complex than a simple small image the fringes can
support, that Lisp program should simply use margins instead.
