Ce fichier sert 脿 d茅finir la police et sa m茅trique.
la m茅thode "findWidth" est incompl猫te. Cette m茅thode a 茅t茅 r茅alis茅e (de mani猫re incompl猫te) 
dans le seul but de servir de support aux exemples utilis茅s permettant de r茅aliser 
l'impl茅mentation. Il faudrait la rendre 
bien plus g茅n茅rale et impl茅menter compl猫tement la m茅trique des polices comme expliqu茅 
dans le rapport. 
Le temps ne m'a pas permi de r茅aliser cette t芒che.
