2987 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2988 it. To see why, you should understand that Windows sends WM_SIZE from
2989 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2990 from some base class ctor and so this WM_SIZE is not processed in the
2991 real class' OnSize() (because it's not fully constructed yet and the
2992 event goes to some base class OnSize() instead). So the WM_SIZE we
2993 rely on is the one sent when the parent frame resizes its children
2994 but here is the problem: if the child already has just the right
2995 size, nothing will happen as both wxWidgets and Windows check for
2996 this and ignore any attempts to change the window size to the size it
2997 already has - so no WM_SIZE would be sent.
