Given that we don't "script" the Emacs display process itself, there is
truly no distinction between a "scriptable" display engine and others.

The MO of Emacs extension code is to modify the contents of a buffer,
and let redisplay do the heavy lifting.  Such an approach will fare
equally irrespective of the representation used for buffer contents.
