+ * Layering & drawing loop of tint2
+ * 
+ * Areas in tint2 are similar to widgets in a GUI. 
+ * Areas (task, clock, systray, taskbar,...) are nodes in a tree.
+ * The position of each Area is defined by parent's position and brothers on the left.

+ * 	- parent node is resized before its children
+ * 	- if 'size' changed then 'resize = 1' on childs with SIZE_BY_LAYOUT
