The option (haven't got a good name for it yet, so let's just call it
"Foo") would cause the display engine to bypass fontification whenever
the event queue is non-empty.  Instead, it would assume all characters
without a `face' property had the Foo property.

Some working code would be a better thing than mere words.  I'm going to
try and hack out a proof of concept.
