On OSX it is changed in LWWindowPeer.notifyReshape.
On windows is changed in awt_Window.cpp. WmMove
In general window manager can set a different size/location than we try 
to set, so we should take a correct values in the callback and update 
the target component, and after that post event that the bounds was changed.

It can be moved by the window manager.
