2988 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2989 it. To see why, you should understand that Windows sends WM_SIZE from
2990 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2991 from some base class ctor and so this WM_SIZE is not processed in the
2992 real class' OnSize() (because it's not fully constructed yet and the
2993 event goes to some base class OnSize() instead). So the WM_SIZE we
2994 rely on is the one sent when the parent frame resizes its children
2995 but here is the problem: if the child already has just the right
2996 size, nothing will happen as both wxWindows and Windows check for
2997 this and ignore any attempts to change the window size to the size it
2998 already has - so no WM_SIZE would be sent.
