3023           specified. This was wrong because wxWidgets programs often assume
3024           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3025           it. To see why, you should understand that Windows sends WM_SIZE from
3026           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3027           from some base class ctor and so this WM_SIZE is not processed in the
3028           real class' OnSize() (because it's not fully constructed yet and the
3029           event goes to some base class OnSize() instead). So the WM_SIZE we
3030           rely on is the one sent when the parent frame resizes its children
3031           but here is the problem: if the child already has just the right
3032           size, nothing will happen as both wxWidgets and Windows check for
3033           this and ignore any attempts to change the window size to the size it
3034           already has - so no WM_SIZE would be sent.
