Yes, it's not a real solution, especially since we don't even have
a "sample" to point to for other people to write&run such tests.
Maybe a better approach would be to allow Emacs to run the redisplay
in batch mode (i.e. build glyph matrices and just do nothing for the
actual redraw).

Indeed, it doesn't solve all display-testing problems. It would be good
enough for the window-configuration-change-hook case and a few others
(e.g. testing window-start and window-end positions, or pixel position
of particular chunks of text), but to do anything more we'd probably
have to provide ways to examine the glyph matrix.

I only meant it for people who want to start writing such tests, in the
absence of actual support for that.
