3038           specified. This was wrong because wxWidgets programs often assume
3039           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3040           it. To see why, you should understand that Windows sends WM_SIZE from
3041           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3042           from some base class ctor and so this WM_SIZE is not processed in the
3043           real class' OnSize() (because it's not fully constructed yet and the
3044           event goes to some base class OnSize() instead). So the WM_SIZE we
3045           rely on is the one sent when the parent frame resizes its children
3046           but here is the problem: if the child already has just the right
3047           size, nothing will happen as both wxWidgets and Windows check for
3048           this and ignore any attempts to change the window size to the size it
3049           already has - so no WM_SIZE would be sent.
