3035           specified. This was wrong because wxWidgets programs often assume
3036           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3037           it. To see why, you should understand that Windows sends WM_SIZE from
3038           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3039           from some base class ctor and so this WM_SIZE is not processed in the
3040           real class' OnSize() (because it's not fully constructed yet and the
3041           event goes to some base class OnSize() instead). So the WM_SIZE we
3042           rely on is the one sent when the parent frame resizes its children
3043           but here is the problem: if the child already has just the right
3044           size, nothing will happen as both wxWidgets and Windows check for
3045           this and ignore any attempts to change the window size to the size it
3046           already has - so no WM_SIZE would be sent.
