	* 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)
