2909       NB: there used to be some code here which set the initial size of the
2910           window to the client size of the parent if no explicit size was
2911           specified. This was wrong because wxWindows programs often assume
2912           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2913           it. To see why, you should understand that Windows sends WM_SIZE from
2914           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2915           from some base class ctor and so this WM_SIZE is not processed in the
2916           real class' OnSize() (because it's not fully constructed yet and the
2917           event goes to some base class OnSize() instead). So the WM_SIZE we
2918           rely on is the one sent when the parent frame resizes its children
2919           but here is the problem: if the child already has just the right
2920           size, nothing will happen as both wxWindows and Windows check for
2921           this and ignore any attempts to change the window size to the size it
2922           already has - so no WM_SIZE would be sent.
