2952           specified. This was wrong because wxWidgets programs often assume
2953           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2954           it. To see why, you should understand that Windows sends WM_SIZE from
2955           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2956           from some base class ctor and so this WM_SIZE is not processed in the
2957           real class' OnSize() (because it's not fully constructed yet and the
2958           event goes to some base class OnSize() instead). So the WM_SIZE we
2959           rely on is the one sent when the parent frame resizes its children
2960           but here is the problem: if the child already has just the right
2961           size, nothing will happen as both wxWidgets and Windows check for
2962           this and ignore any attempts to change the window size to the size it
2963           already has - so no WM_SIZE would be sent.
