* base class for all graphical objects (panel, taskbar, task, systray, clock, ...).

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

|
* Area manage the background and border drawing, size and padding.
|
|
* Each Area have 2 Pixmap (pix and pix_active).
|
|
*
|
|
* Area manage the tree of all objects. Parent object drawn before child object.
|

* panel -> taskbars -> tasks
|
|
* -> systray -> icons
|
|
* -> clock
|
|
*
|
|
* draw_foreground(obj) and resize(obj) are virtual function.
