3023 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3024 it. To see why, you should understand that Windows sends WM_SIZE from
3025 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3026 from some base class ctor and so this WM_SIZE is not processed in the
3027 real class' OnSize() (because it's not fully constructed yet and the
3028 event goes to some base class OnSize() instead). So the WM_SIZE we
3029 rely on is the one sent when the parent frame resizes its children
3030 but here is the problem: if the child already has just the right
3031 size, nothing will happen as both wxWindows and Windows check for
3032 this and ignore any attempts to change the window size to the size it
3033 already has - so no WM_SIZE would be sent.
