Le vecteur vitesse est cod� en flottant et il est possible de modifier

sa largeur.
Correction de bugs tr�s g�nants dans l'appel de l'antirec.
Correction de la spec associ�e avec l'option -lastasfirst : maintenant
la derniere pos prend la couleur du symbole de tete lorsque le nombre
de pos pass�es est atteint.
