2942           specified. This was wrong because wxWidgets programs often assume
2943           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2944           it. To see why, you should understand that Windows sends WM_SIZE from
2945           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2946           from some base class ctor and so this WM_SIZE is not processed in the
2947           real class' OnSize() (because it's not fully constructed yet and the
2948           event goes to some base class OnSize() instead). So the WM_SIZE we
2949           rely on is the one sent when the parent frame resizes its children
2950           but here is the problem: if the child already has just the right
2951           size, nothing will happen as both wxWidgets and Windows check for
2952           this and ignore any attempts to change the window size to the size it
2953           already has - so no WM_SIZE would be sent.
