. yuv pour le 8 bits noir et blanc 

 . yuv 8 bits couleur (bon c'est moche pour le moment, mais �a vient)
 . correction de "convertion" en "conversion" un peu partout :)

� faire encore : allouer dynamiquement la lookup table pour la YUV 8 bits,
parce que directement dans p_vout �a pue un peu, faire le changement de
palette qui va bien au passage couleur / n&b.
