Modification mineure MotionComponent : changement d'une boucle imbriquee

sur i_y et i_y1 en une boucle simple sur i_y... Le changement en vitesse comme
en taille est chouillatique mais neanmoins positif. Ca n'a pas d'effet sur
l'unrolling de boucle car celui-ci est effectue sur une boucle plus interne...
