internal: target window ID for the source event is 0

[wavexx]

xlib.xKeyButtonPointer.event/child are 0 when read from the event stream. Bad decoding/packing, or missing info from XRecord?

See https://github.com/wavexx/screenkey/issues/44#issuecomment-313881370 and following comments.

Looked over the Window values for the Focus changes and they all report 0

Also tried implementing XPropertyChange to watch for _NET_ACTIVE_WINDOW. But doesn't seem like it gets used.
