+* Area is at the begining of each object (&object == &area).

 * Area manage the background and border drawing, size and padding.
-* Area also manage the tree of visible objects
+* Each Area have 2 Pixmap (pix and pix_active).

+* Area also manage the tree of visible 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()
-* variable widthChanged ou bien emission d'un signal ???
 * voir config(obj) configure un objet (définie les positions verticales)
