Track from Pose Scan

Turns a pose scan into a skeleton track (input of Fit Track to Character): mirrored to face right if needed, near side labelled R, both feet on one ground line, planted feet locked. mode 'walk cycle': one cycle start..start+period-1 closed into a seamless loop, planted feet moving back at one treadmill speed (a walk across the frame is put on a treadmill first); period 0 = found automatically; frames 0 = just over two cycles. mode 'one-shot': the frames start..start+frames-1 as they are (punch, kick, step-in), planted feet held still. The preview draws the track over the video: R = near = orange, L = far = blue, green = planted.
