I'd prefer not to lose the "e" interactive spec and the form of the
argument here.  If the problem is the conversion of window-relative to
frame-relative coordinates, that is easy, and the ELisp manual has an
example of how to do that in the node "Accessing Mouse".

Or is there some problem to use this here?
