2916           window to the client size of the parent if no explicit size was
2917           specified. This was wrong because wxWindows programs often assume
2918           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2919           it. To see why, you should understand that Windows sends WM_SIZE from
2920           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2921           from some base class ctor and so this WM_SIZE is not processed in the
2922           real class' OnSize() (because it's not fully constructed yet and the
2923           event goes to some base class OnSize() instead). So the WM_SIZE we
2924           rely on is the one sent when the parent frame resizes its children
2925           but here is the problem: if the child already has just the right
2926           size, nothing will happen as both wxWindows and Windows check for
2927           this and ignore any attempts to change the window size to the size it
2928           already has - so no WM_SIZE would be sent.
