But the frame geometry mightn't always be said to change just because 
display geometry changes in current window systems, AFAIK  e.g. on X11, 
you'd want a hook run when emacs [selects for] and gets an xrandr 
XRRScreenChangeNotify event, I think.  Could be a separate 
display-configuration-change-hook or maybe another trigger of 
window-configuration-change hook.

I reckon it's a reasonable feature request, anyway (Edward, you could 
maybe file a wishlist item in the bug tracker?), though I confess I 
haven't checked the current code's behaviour on display hotplug changes.
