FusionEngine now attaches a secondary location that has never seen GPS data to its result. LocationFudger uses the GPS-less location so that COARSE apps never see data from the GPS provider. When the previous location is updated, the previous GPS-less location is carried over if the location update was GPS-only. Additionally, apps without FINE permission are not notified when GPS location changes, and any attempt to use GPS_PROVIDER without FINE permission is met by a stern SecurityException.
