2958 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2959 it. To see why, you should understand that Windows sends WM_SIZE from
2960 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2961 from some base class ctor and so this WM_SIZE is not processed in the
2962 real class' OnSize() (because it's not fully constructed yet and the
2963 event goes to some base class OnSize() instead). So the WM_SIZE we
2964 rely on is the one sent when the parent frame resizes its children
2965 but here is the problem: if the child already has just the right
2966 size, nothing will happen as both wxWidgets and Windows check for
2967 this and ignore any attempts to change the window size to the size it
2968 already has - so no WM_SIZE would be sent.
