Bug #588373 - Menus broken by client-side-windows
Bug #588373 - Menus broken by client-side-windows

Resurrcetion and adaption of find_window_for_mouse_event(). The window
receiving the WM_MOUSEMOVE, WM_?BUTTONDOWN is not necessarily the one
interested in GDK_(ENTER|MOTION|LEAVE)_NOTIFY

http://bugzilla.gnome.org/show_bug.cgi?id=588373

Also added some more more TODO_CSW and disabled print_event(): it can not
cope with the new _gdk_windowing_got_event() eating/morphing events.
