The correction models, filters, blink filter, and SteamVR log reader move
out of the probe so the gaze service can use them too. Two additions on the
way: the log reader follows the headset going on and off (SteamVR starts its
eye model over each time it goes on), and LiveCorrection counts lessons from
before the last time it went on less (OLD_WEAR), so the first few after
relearn the offset while the shape is kept.
