+Subject: [PATCH] Copy out of proximity values into current values selectively
+
+Otherwise, an event that causes us to go into proximity with some new
+valuator values will retain some old valuator values from when last in
+proximity. This change ensures that all values posted while out of
+proximity are accounted for.
