3027 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3028 it. To see why, you should understand that Windows sends WM_SIZE from
3029 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3030 from some base class ctor and so this WM_SIZE is not processed in the
3031 real class' OnSize() (because it's not fully constructed yet and the
3032 event goes to some base class OnSize() instead). So the WM_SIZE we
3033 rely on is the one sent when the parent frame resizes its children
3034 but here is the problem: if the child already has just the right
3035 size, nothing will happen as both wxWindows and Windows check for
3036 this and ignore any attempts to change the window size to the size it
3037 already has - so no WM_SIZE would be sent.
