/* Considérons le segment de ligne l (AB) et le cercre centré en C
Le point D est la projection de AC sur AB.
DC est le vecteur entre D et C.
Lorsque que la norme de DC est plus petite que le rayon, nous savons qu'il
y a une intersection sur la ligne AB. Il reste a determiner si le point
d'intersection est sur le segment AB.
Ensuite on détermine s'il y a 1 ou 2 points d'intersections. Lorsque la
norme de DC est strictement égale au rayon, il n'y a qu'une intersection parce
que AB est tangente au cercle.
Si la norme de DC est plus petite que le rayon, il y aura 2 intersections.
Ensuite, pour chaque intersection, il faut d'éterminer le point précis de
l'intersection (E) et déterminer si ce point est sur le segment AB.
Dans le cas de la tangente, le point d'intersection est déterminer par la
projection AC sur AB.
Dans l'autre cas, on trouve le point d'intersection par trigonométrie. On
connais le rayon et le point D. Par c^2 = a^2 + b^2 (triangle rectangle), on
peut trouver la norme de ED. Ensuite les deux points d'intersections sont
défini comme AD - ED et AD + ED.
Pour terminer, afin de determiner si E est sur le segment AB on s'assure
que le produit scalaire AB * AE est positif et que la norme de AB est plus
grande qye la norme de AE
