Well the event is `redisplay', and indeed if we had
a before-redisplay-hook, we could use it to do that in Lisp (although
we'd bump into another problem: faces can't be set per-window.
Tho maybe with a redisplay-window-hook we could trick the display into
using different face settings for different windows).
