3012 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3013 it. To see why, you should understand that Windows sends WM_SIZE from
3014 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3015 from some base class ctor and so this WM_SIZE is not processed in the
3016 real class' OnSize() (because it's not fully constructed yet and the
3017 event goes to some base class OnSize() instead). So the WM_SIZE we
3018 rely on is the one sent when the parent frame resizes its children
3019 but here is the problem: if the child already has just the right
3020 size, nothing will happen as both wxWidgets and Windows check for
3021 this and ignore any attempts to change the window size to the size it
3022 already has - so no WM_SIZE would be sent.
