* - Contrainte: m_Start.x = m_End.x ( self verticale )

* Mself.lbrin = longueur d'un brin
* Mself.rayon = rayon des parties arrondies du serpentin

* Les equations sont
* Mself.m_Size.x = 2*Mself.rayon + Mself.lbrin
* Mself.m_Size.y = 2*Mself.delta + 2*Mself.nbrin*Mself.rayon

* Les contraintes sont:
* nbrin >= 2
* Mself.rayon < Mself.m_Size.x
* Mself.m_Size.y = Mself.rayon*4 + 2*Mself.raccord
* Mself.lbrin > Mself.rayon *2

* Le calcul est conduit de la facon suivante:
* Initialement:
* nbrin = 2
* rayon = 4 * m_Size.x (valeur fixe arbitraire)
* puis:
* on augmente le nombre de brins jusqu'a la longueur desiree
* ( le rayon est diminue si necessaire )
