I am sorry, but I discovered worse things : the "position" property is
relative to the parent at creation time, but when you move a widget
by changing its position, then children stay stuck on the root window.
See the example code :

f=uicontrol('style','frame','position',[100 100 100 100]);
b=uicontrol(f,'style','pushbutton','position',[0 0 100 
20],'string','push me');
f.position=[0 0 100 100]

Is it a bug or a feature ?
