is there a hook for when a buffer loses/gains the cursor or the frame loses/gains focus?

go me thinking that it would be nice to save every time the buffer loses
the cursor.  Is there a way in Emacs to do that?  Similarly, I'd like to
save every time the frame loses focus.  I didn't find any hooks or
functions for this.

Thanks

I don't think there is such a thing yet.  We have a `switch-frame'
event, but it's only triggered when you enter another frame, not when
you leave a frame (if your whole display is covered with nothing but
Emacs frames, it's equivalent, of course, but not in general).
