2867 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2868 it. To see why, you should understand that Windows sends WM_SIZE from
2869 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2870 from some base class ctor and so this WM_SIZE is not processed in the
2871 real class' OnSize() (because it's not fully constructed yet and the
2872 event goes to some base class OnSize() instead). So the WM_SIZE we
2873 rely on is the one sent when the parent frame resizes its children
2874 but here is the problem: if the child already has just the right
2875 size, nothing will happen as both wxWindows and Windows check for
2876 this and ignore any attempts to change the window size to the size it
2877 already has - so no WM_SIZE would be sent.
