* Area manage the background and border drawing, size and padding.
* Each Area have 2 Pixmap (pix and pix_active).
*
-* Area also manage the tree of visible objects. Parent object drawn before child object.
+* Area manage the tree of all objects. Parent object drawn before child object.
* panel -> taskbars -> tasks
* -> systray -> icons
* -> clock
*
-* draw_foreground(obj) is virtual function.
-*
-* 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
-*
-* voir resize_taskbar(), resize_clock() et resize_tasks()
-* voir config(obj) configure un objet (définie les positions verticales)
+* draw_foreground(obj) and resize(obj) are virtual function.
