2988           specified. This was wrong because wxWidgets programs often assume
2989           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2990           it. To see why, you should understand that Windows sends WM_SIZE from
2991           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2992           from some base class ctor and so this WM_SIZE is not processed in the
2993           real class' OnSize() (because it's not fully constructed yet and the
2994           event goes to some base class OnSize() instead). So the WM_SIZE we
2995           rely on is the one sent when the parent frame resizes its children
2996           but here is the problem: if the child already has just the right
2997           size, nothing will happen as both wxWidgets and Windows check for
2998           this and ignore any attempts to change the window size to the size it
2999           already has - so no WM_SIZE would be sent.
