2955           specified. This was wrong because wxWidgets programs often assume
2956           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2957           it. To see why, you should understand that Windows sends WM_SIZE from
2958           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2959           from some base class ctor and so this WM_SIZE is not processed in the
2960           real class' OnSize() (because it's not fully constructed yet and the
2961           event goes to some base class OnSize() instead). So the WM_SIZE we
2962           rely on is the one sent when the parent frame resizes its children
2963           but here is the problem: if the child already has just the right
2964           size, nothing will happen as both wxWidgets and Windows check for
2965           this and ignore any attempts to change the window size to the size it
2966           already has - so no WM_SIZE would be sent.
