3025 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3026 it. To see why, you should understand that Windows sends WM_SIZE from
3027 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3028 from some base class ctor and so this WM_SIZE is not processed in the
3029 real class' OnSize() (because it's not fully constructed yet and the
3030 event goes to some base class OnSize() instead). So the WM_SIZE we
3031 rely on is the one sent when the parent frame resizes its children
3032 but here is the problem: if the child already has just the right
3033 size, nothing will happen as both wxWidgets and Windows check for
3034 this and ignore any attempts to change the window size to the size it
3035 already has - so no WM_SIZE would be sent.
