3041 from some base class ctor and so this WM_SIZE is not processed in the
3042 real class' OnSize() (because it's not fully constructed yet and the
3043 event goes to some base class OnSize() instead). So the WM_SIZE we
3044 rely on is the one sent when the parent frame resizes its children
3045 but here is the problem: if the child already has just the right
3046 size, nothing will happen as both wxWidgets and Windows check for
3047 this and ignore any attempts to change the window size to the size it
3048 already has - so no WM_SIZE would be sent.
