* DRAWING AND LAYERING ENGINE :
* Redrawing an object (like the clock) could come from an 'external event' (date change)
* or from a 'layering event' (position change).
- * The following 'drawing engine' take care of all 'layering event'.
+ * The following 'drawing engine' take care of :
+ * - posx/posy of all Area
+ * - 'layering event' propagation between object
* 1) browse tree SIZE_BY_CONTENT
* - resize SIZE_BY_CONTENT node : children are resized before parent
* - if 'size' changed then 'resize = 1' on the parent
*
