Move it to emacs-devel.  But if you want it to work for "multi-glyph"
situations (such as trees), then the main problem will be how to
design it.  So, rather than discuss, it might be better to try and come
up with a preliminary implementation.

The situation for EWW (and Custom) is fairly different since relative
alignment is not that important, so the mapping can be done for each
glyph individually, so the system can be fairly simple.
