2954           specified. This was wrong because wxWidgets programs often assume
2955           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2956           it. To see why, you should understand that Windows sends WM_SIZE from
2957           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2958           from some base class ctor and so this WM_SIZE is not processed in the
2959           real class' OnSize() (because it's not fully constructed yet and the
2960           event goes to some base class OnSize() instead). So the WM_SIZE we
2961           rely on is the one sent when the parent frame resizes its children
2962           but here is the problem: if the child already has just the right
2963           size, nothing will happen as both wxWidgets and Windows check for
2964           this and ignore any attempts to change the window size to the size it
2965           already has - so no WM_SIZE would be sent.
