Subject: [PATCH] gdk: protect better against crossing events with
 sourceid=touchscreen

_gdk_windowing_got_event() tries to some extent to make all events have
a meaningful source device (eg a slave device), this triggered some paths
to get crossing events with sourceid=touchscreen that surpassed the checks
to wrap the "pointer emulating" touch event sequence with a crossing event
pair.
