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 ...

​posn-area reports whether the event was in the text area or not.​

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.

​It does seem like some additional work is needed to simplify event handling and handle a multi-frame world better.
