2985 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2986 it. To see why, you should understand that Windows sends WM_SIZE from
2987 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2988 from some base class ctor and so this WM_SIZE is not processed in the
2989 real class' OnSize() (because it's not fully constructed yet and the
2990 event goes to some base class OnSize() instead). So the WM_SIZE we
2991 rely on is the one sent when the parent frame resizes its children
2992 but here is the problem: if the child already has just the right
2993 size, nothing will happen as both wxWindows and Windows check for
2994 this and ignore any attempts to change the window size to the size it
2995 already has - so no WM_SIZE would be sent.
