3014 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3015 it. To see why, you should understand that Windows sends WM_SIZE from
3016 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3017 from some base class ctor and so this WM_SIZE is not processed in the
3018 real class' OnSize() (because it's not fully constructed yet and the
3019 event goes to some base class OnSize() instead). So the WM_SIZE we
3020 rely on is the one sent when the parent frame resizes its children
3021 but here is the problem: if the child already has just the right
3022 size, nothing will happen as both wxWindows and Windows check for
3023 this and ignore any attempts to change the window size to the size it
3024 already has - so no WM_SIZE would be sent.
