3026           specified. This was wrong because wxWindows programs often assume
3027           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3028           it. To see why, you should understand that Windows sends WM_SIZE from
3029           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3030           from some base class ctor and so this WM_SIZE is not processed in the
3031           real class' OnSize() (because it's not fully constructed yet and the
3032           event goes to some base class OnSize() instead). So the WM_SIZE we
3033           rely on is the one sent when the parent frame resizes its children
3034           but here is the problem: if the child already has just the right
3035           size, nothing will happen as both wxWindows and Windows check for
3036           this and ignore any attempts to change the window size to the size it
3037           already has - so no WM_SIZE would be sent.
