Nautilus assumes that the pointer returned by gdk_seat_get_pointer will
return the same GdkDevice which started a rubberband action. This is
not necessarily the case, however. Under Wayland, for example, tablet
tools have pointers (and GdkDevice's) which are entirely separate from
the seat's primary mouse-driven pointer. Attempting to use a pen to
perform rubberband selection will result in the rectangle being drawn
with the incorrect coordinates.

This patch has the code store the GdkDevice which generated the event
and provides it in place of the call to gdk_seat_get_pointer.
