A clarification on what exactly is expected of tabulated-list-mode with
regards to the current issue and how it fails to (in an unamendable way)
fulfill those expectations would be appreciated.

Image resizing can be handled the same way `tabulated-list-printer' is
currently handled; as a variable that points to a function, whose
built-in value supports most common needs.  That would solve the issue
of packages being incapable of controlling the process.

As it stands, the variable `tabulated-list-printer' is used to control
the way printing is done and any package that wants to print differently
should be setting that variable to their own printing function.
Packages should not be exposed to the printing process unless they are
offering functionality that /cannot/ be handled by tabulated-list.

PPS: I am thinking of carrying this conversation over to emacs-devel.
     Are you okay with that?
