2955 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2956 it. To see why, you should understand that Windows sends WM_SIZE from
2957 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2958 from some base class ctor and so this WM_SIZE is not processed in the
2959 real class' OnSize() (because it's not fully constructed yet and the
2960 event goes to some base class OnSize() instead). So the WM_SIZE we
2961 rely on is the one sent when the parent frame resizes its children
2962 but here is the problem: if the child already has just the right
2963 size, nothing will happen as both wxWidgets and Windows check for
2964 this and ignore any attempts to change the window size to the size it
2965 already has - so no WM_SIZE would be sent.
