Calcul les "coordonnée local relative" d'un point p dans un quadrilatere [abcd].

Ex.: Example "rectangulaire" resultat pp={2.5,2.5} 

Point2D<float> a,b,c,d,p,pp;
a.Set(0,0);
b.Set(10,0);
c.Set(10,10);
c.Set(0,10);
p.Set(2.5,2.5);
BOOL res = p.GetRelativePtOnQuadrilatere(&a,&b,&c,&d,&pp);

Ex.: Example "quelquonque" resultat pp={2.5,2.5} 

Point2D<float> a,b,c,d,p,pp;
a.Set(0,0);
b.Set(20,0);
c.Set(10,20);
c.Set(0,10);
p.Set(2.5,2.5);
BOOL res = p.GetRelativePbOnQuadrilatere(&a,&b,&c,&d,&pp);
