No, indeed, there isn't. You can use window-configuration-change-hook
to detect changes within an Emacs frame, but in order to detect focus
changing from/to Emacs to/from other applications you'd additionally
need a focus-hook, but last I checked the corresponding C-level events
are not reliably propagated to Elisp. Patch welcome.
