3030           specified. This was wrong because wxWindows programs often assume
3031           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3032           it. To see why, you should understand that Windows sends WM_SIZE from
3033           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3034           from some base class ctor and so this WM_SIZE is not processed in the
3035           real class' OnSize() (because it's not fully constructed yet and the
3036           event goes to some base class OnSize() instead). So the WM_SIZE we
3037           rely on is the one sent when the parent frame resizes its children
3038           but here is the problem: if the child already has just the right
3039           size, nothing will happen as both wxWindows and Windows check for
3040           this and ignore any attempts to change the window size to the size it
3041           already has - so no WM_SIZE would be sent.
