Carlos Garnacho 07b1a2e081 GdkDeviceManagerCore: protect against xevent->xany.window not being a GdkWindow.
Conceivably this GdkEventTranslator may still be asked for events such as
NoExpose or GraphicsExpose for pixmaps. It is not meant to translate such events,
but should at least behave with them.
