Ok, in that case we can properly deprecate this once we have an
alternative (see above). I still think losing the ability to include
(external) vector graphics is a loss, though.
What are the chances of having a conversion tool that produces
LilyPond markup commands for the vectors in formats such as EPS?
Perhaps as an eps2ly or something.
I agree with Jonas that it would be a considerable loss not to be able
to import vector graphics. I don't concur with Jean's argument that one
can replace them by using markup commands: One obvious use case for
proper vector import would be including a publisher's logo, for instance.
That being said: My uneducated guess would be that with Cairo etc., it
might be more natural/easy to import vector graphics in SVG format than
in EPS?
