3259 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3260 it. To see why, you should understand that Windows sends WM_SIZE from
3261 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3262 from some base class ctor and so this WM_SIZE is not processed in the
3263 real class' OnSize() (because it's not fully constructed yet and the
3264 event goes to some base class OnSize() instead). So the WM_SIZE we
3265 rely on is the one sent when the parent frame resizes its children
3266 but here is the problem: if the child already has just the right
3267 size, nothing will happen as both wxWidgets and Windows check for
3268 this and ignore any attempts to change the window size to the size it
3269 already has - so no WM_SIZE would be sent.
