3029           specified. This was wrong because wxWindows programs often assume
3030           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3031           it. To see why, you should understand that Windows sends WM_SIZE from
3032           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3033           from some base class ctor and so this WM_SIZE is not processed in the
3034           real class' OnSize() (because it's not fully constructed yet and the
3035           event goes to some base class OnSize() instead). So the WM_SIZE we
3036           rely on is the one sent when the parent frame resizes its children
3037           but here is the problem: if the child already has just the right
3038           size, nothing will happen as both wxWindows and Windows check for
3039           this and ignore any attempts to change the window size to the size it
3040           already has - so no WM_SIZE would be sent.
