Part fix for bug id 4017222. Return the widget at the given screen coords

null if the pointer is not over the root widget or child of the root widget.
Additionally, this function will only return a Widget with non-nil XmNuserData.
In 1.2.1, when the mouse was dragged over a Choice component, this function
returned the GadgetButton associated with the Choice. This GadgetButton had
nil as its XmNuserData. This lead to a crash when the nil XmNuserData was
extracted and used as a reference to a peer. Ooops.
Now the GadgetButton is not returned and the function goes on to find a widget
which contains the correct peer reference in XmNuserData.
