2958           specified. This was wrong because wxWidgets programs often assume
2959           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2960           it. To see why, you should understand that Windows sends WM_SIZE from
2961           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2962           from some base class ctor and so this WM_SIZE is not processed in the
2963           real class' OnSize() (because it's not fully constructed yet and the
2964           event goes to some base class OnSize() instead). So the WM_SIZE we
2965           rely on is the one sent when the parent frame resizes its children
2966           but here is the problem: if the child already has just the right
2967           size, nothing will happen as both wxWidgets and Windows check for
2968           this and ignore any attempts to change the window size to the size it
2969           already has - so no WM_SIZE would be sent.
