2956 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2957 it. To see why, you should understand that Windows sends WM_SIZE from
2958 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2959 from some base class ctor and so this WM_SIZE is not processed in the
2960 real class' OnSize() (because it's not fully constructed yet and the
2961 event goes to some base class OnSize() instead). So the WM_SIZE we
2962 rely on is the one sent when the parent frame resizes its children
2963 but here is the problem: if the child already has just the right
2964 size, nothing will happen as both wxWidgets and Windows check for
2965 this and ignore any attempts to change the window size to the size it
2966 already has - so no WM_SIZE would be sent.
