La position de chaque face dans la cubemap
Les indices ici seront multipliés à la taille d'une face pour obtenir le coin haut-gauche de la zone.
Si la taille d'une face est 0, elle sera calculée via max(width, height)/4.
Par défaut, cela suit ce layout :
U
L F R B
D
Si ce n'est pas le cas, à vous de repositionner les faces correctement.
