3033           specified. This was wrong because wxWindows programs often assume
3034           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3035           it. To see why, you should understand that Windows sends WM_SIZE from
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 wxWindows 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.
