  40 pour version 0.7
  41 gestion du systray
  42   positionnement et taille fixe du systray (objet systray)
  43   détection des notifications (détection des icones, ajout a la liste)
  44   ajouter la transparence des icones
  45   gérer le redimentionnement des éléments
  46     => voir si lon peut faire abstraction sur le positionnement des objets ?
  47        sachant que certains objets (task, taskbar) on une taille définit par l'extérieur
  48        et d'autres objets (clock, systray) on une taille définit par l'intérieur
  49
  50 gestion du layout
  51   voir le positionnement des taskbar, task et systray
  52   définir panel_layout dans la configuration
  53   comment gérer le multi panel avec des layouts différents
  54
  55 vérifier le niveau d'abstraction du code
  56   utiliser la fonction draw(obj) récurrente sur Taskbar, Task, Systray, Clock
  57   est ce compatible avec l'affichage de la tache active et les changement de taille -> redessine le panel
  58
  59 correction de bugs :
  60   memory, segfault
  61   background
  62   remettre en place single_desktop avec nouveau layout
  63   remettre en place multi_monitor avec nouveau layout
  64   vérifier le changement de configuration
  65
  66 pour version 0.8
  67 gestion du thème
  68   voir la gestion du dégradé sur le bord et le fond (inkscape)
  69   faut-il trois coordonnées de padding x, y, x inter-objects
  70
  71 gestion du zoom
  72   définir le zoom du panel
