2891 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2892 it. To see why, you should understand that Windows sends WM_SIZE from
2893 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2894 from some base class ctor and so this WM_SIZE is not processed in the
2895 real class' OnSize() (because it's not fully constructed yet and the
2896 event goes to some base class OnSize() instead). So the WM_SIZE we
2897 rely on is the one sent when the parent frame resizes its children
2898 but here is the problem: if the child already has just the right
2899 size, nothing will happen as both wxWindows and Windows check for
2900 this and ignore any attempts to change the window size to the size it
2901 already has - so no WM_SIZE would be sent.
