If we start talking about "event ends" here we should export that
concept to the remaining ‘posn-*’ functions as well.

I suppose this is not sufficient: We get a frame also when the mouse is
on its tool or menu bar, some of ist borders ...

But note that I've never been able to understand the purpose of these
‘posn-*’ functions and they usually confuse the hell out of me.  IMHO it
would make much more sense to declare them obsolete and concentrate on
describing event structures better.
