2999 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3000 it. To see why, you should understand that Windows sends WM_SIZE from
3001 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3002 from some base class ctor and so this WM_SIZE is not processed in the
3003 real class' OnSize() (because it's not fully constructed yet and the
3004 event goes to some base class OnSize() instead). So the WM_SIZE we
3005 rely on is the one sent when the parent frame resizes its children
3006 but here is the problem: if the child already has just the right
3007 size, nothing will happen as both wxWindows and Windows check for
3008 this and ignore any attempts to change the window size to the size it
3009 already has - so no WM_SIZE would be sent.
