Does the way the list of the (up to 4) tracked IR dots is returned by the library/wiimote follows any logic ?
Can I make any assumption like :

-- the wiimote tries to track them like keeping first found first in the list ?
or
-- they get sorted from left to right then top to bottom in the camera image ?
or
-- they are sorted by decreasing size
or
-- cannot make any assumtion, can be totally random, with a potential flip every frame...

Does the library/wiimote have any internal state that makes it remember a previous found dot to assign it again the same order.
