2927 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2928 it. To see why, you should understand that Windows sends WM_SIZE from
2929 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2930 from some base class ctor and so this WM_SIZE is not processed in the
2931 real class' OnSize() (because it's not fully constructed yet and the
2932 event goes to some base class OnSize() instead). So the WM_SIZE we
2933 rely on is the one sent when the parent frame resizes its children
2934 but here is the problem: if the child already has just the right
2935 size, nothing will happen as both wxWindows and Windows check for
2936 this and ignore any attempts to change the window size to the size it
2937 already has - so no WM_SIZE would be sent.
