Would change_frame_size be aware of such a geometry change?  IIUC
the original request

https://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00544.html

Edward would really just want a completely separate hook that reports to
Emacs the identity of the changed display and maybe its new geometry and
is only called in those, IMO very rare, occasions.  Or what am I missing
here?
