Subject: [PATCH] Bug 668239 - texts disappear when notebook switch page at
 zh_CN locate

In gtkimcontextime.c, use gdk_win32_window_get_impl_hwnd() to get to
the impl's existing native window instead of GDK_WINDOW_HWND() which
implicitly ensures a native window for the widget itself. This seems
to work around whatever GDK problem with native subwindows and fixes
the bug.
