* Area also manage the tree of visible objects. Parent object drawn before child object.

* TODO :
* resize_width(obj, width) = 0 : fonction virtuelle à redéfinir
*    recalcule la largeur de l'objet (car la hauteur est fixe)
*    - taille systray calculée à partir de la liste des icones
*    - taille clock calculée à partir de l'heure
*    - taille d'une tache calculée à partir de la taskbar (ajout, suppression, taille)
*    - taille d'une taskbar calculée à partir de la taille du panel et des autres objets
