	* gdk/win32/gdkevents-win32.c
	* gdk/win32/gdkwindow-win32.[ch]: Fix transient windows on Win32 
	so that when a transient child window is closed (particularly when 
	there are 3 or more levels of transient windows), the correct window
	receives focus rather than a seemingly random window. (#112404)

/* Cannot use TrackMouseEvent, as the stupid WM_MOUSELEAVE message
* doesn't tell us where the mouse has gone. Thus we cannot use it to
* generate a correct GdkNotifyType. Pity, as using TrackMouseEvent
* otherwise would make it possible to reliably generate
* GDK_LEAVE_NOTIFY events, which would help get rid of those pesky
* tooltips sometimes popping up in the wrong place.
*
* 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
* not have TrackMouseEvent at all (?) --hb
