Thanks Eli, maybe I understand what you mean but I am a bit surprised.

The Mozilla display engine displays images and text with different
properties very well. And it is very flexible in its way to do that
(since CSS requires that).

I guess it does not directly has something that reminds of "special
properties", but would that be hard to add?

Another point is of course searching for the properties. But Emacs has
its own difficulties there (overlays).
