nitpicker: update hover state on touch events

Browse Source 
The hover state is evaluated for the routing of input events. When
routing a touch event, the decision should be based on the most recently
observed touch position. Without this patch, however, the hover state kept
referring to the initial pointer position (screen center) in the absence
of any other motion events.
