In initial implementation, I thought hand identification needed to be swapped due to mirror imageness.
That's actually wrong, because although the webcam image is mirrored, we want the hands displayed on screen to match the hands in real life. So don't swap left/right.
Because I was always testing with 2 x white hands, I never actually noticed, but in all previous versions, left & right hands were swapped over.
