2989           specified. This was wrong because wxWidgets programs often assume
2990           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2991           it. To see why, you should understand that Windows sends WM_SIZE from
2992           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2993           from some base class ctor and so this WM_SIZE is not processed in the
2994           real class' OnSize() (because it's not fully constructed yet and the
2995           event goes to some base class OnSize() instead). So the WM_SIZE we
2996           rely on is the one sent when the parent frame resizes its children
2997           but here is the problem: if the child already has just the right
2998           size, nothing will happen as both wxWidgets and Windows check for
2999           this and ignore any attempts to change the window size to the size it
3000           already has - so no WM_SIZE would be sent.
