There are two (admittedly rather old) bug reports requesting these two
features. The second one pretty much being dependent on the first one.
https://bugzilla.gnome.org/show_bug.cgi?id=383667
https://bugzilla.gnome.org/show_bug.cgi?id=589848

The main problem with these is that the image viewing widget doesn't
have a way to get image coordinates from pointer coordinates. Though
one might be able to build something from the mouse-wheel-zoom code.
It's relatively low on my agenda though as there are other parts in eog
that are in serious need of maintenance.

Well, if the general coordinate mapping parts mentioned above are
implemented (and part of the public API) this should be doable as a
plugin.
