2947           specified. This was wrong because wxWidgets programs often assume
2948           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2949           it. To see why, you should understand that Windows sends WM_SIZE from
2950           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2951           from some base class ctor and so this WM_SIZE is not processed in the
2952           real class' OnSize() (because it's not fully constructed yet and the
2953           event goes to some base class OnSize() instead). So the WM_SIZE we
2954           rely on is the one sent when the parent frame resizes its children
2955           but here is the problem: if the child already has just the right
2956           size, nothing will happen as both wxWidgets and Windows check for
2957           this and ignore any attempts to change the window size to the size it
2958           already has - so no WM_SIZE would be sent.
