* doesn’t tell us where the mouse has gone. Thus we cannot use it to
|

* otherwise would make it possible to reliably generate

* GDK_LEAVE_NOTIFY events, which would help get rid of those pesky

|

*
|

* Update: a combination of TrackMouseEvent, GetCursorPos and
|
||
* GetWindowPos can and is actually used to get rid of those
|
||
* pesky tooltips. It should be possible to use this for the
|
||
* whole ENTER/LEAVE NOTIFY handling but some platforms may
