For a general-purpose display testing, we need to add code to the
display engine (both its high-level device-independent part, and
lower-level display backend) that would expose to a Lisp application
the glyphs that are produced by the display engine and the
backend-dependent display commands sent to the display API
(termcap/terminfo for text terminal, X for X Window system, etc.).
That sounds like a big job, and most of it for no purpose other than
testing. I tend to doubt it would pay for itself in terms
of future effort saved.
