2957           specified. This was wrong because wxWidgets programs often assume
2958           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2959           it. To see why, you should understand that Windows sends WM_SIZE from
2960           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2961           from some base class ctor and so this WM_SIZE is not processed in the
2962           real class' OnSize() (because it's not fully constructed yet and the
2963           event goes to some base class OnSize() instead). So the WM_SIZE we
2964           rely on is the one sent when the parent frame resizes its children
2965           but here is the problem: if the child already has just the right
2966           size, nothing will happen as both wxWidgets and Windows check for
2967           this and ignore any attempts to change the window size to the size it
2968           already has - so no WM_SIZE would be sent.
