2973 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2974 it. To see why, you should understand that Windows sends WM_SIZE from
2975 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2976 from some base class ctor and so this WM_SIZE is not processed in the
2977 real class' OnSize() (because it's not fully constructed yet and the
2978 event goes to some base class OnSize() instead). So the WM_SIZE we
2979 rely on is the one sent when the parent frame resizes its children
2980 but here is the problem: if the child already has just the right
2981 size, nothing will happen as both wxWidgets and Windows check for
2982 this and ignore any attempts to change the window size to the size it
2983 already has - so no WM_SIZE would be sent.
