Il est 6 heure du matin et le parser ... parse !!!!!!!!
Ca � l'air de pas trop mal marcher. Parmis les bugs les plus sauvages
on trouve :
1) le DumpBits sans NeedBits (corrig� par un RemoveBits)
2) Une table � laquelle il manquait une ligne
3) le test de fin de boucle du d�codage des coef dct �tait mal plac�

Meuh, � toi de jouer
