3036 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3037 from some base class ctor and so this WM_SIZE is not processed in the
3038 real class' OnSize() (because it's not fully constructed yet and the
3039 event goes to some base class OnSize() instead). So the WM_SIZE we
3040 rely on is the one sent when the parent frame resizes its children
3041 but here is the problem: if the child already has just the right
3042 size, nothing will happen as both wxWidgets and Windows check for
3043 this and ignore any attempts to change the window size to the size it
3044 already has - so no WM_SIZE would be sent.
