2953 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
2954 it. To see why, you should understand that Windows sends WM_SIZE from
2955 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
2956 from some base class ctor and so this WM_SIZE is not processed in the
2957 real class' OnSize() (because it's not fully constructed yet and the
2958 event goes to some base class OnSize() instead). So the WM_SIZE we
2959 rely on is the one sent when the parent frame resizes its children
2960 but here is the problem: if the child already has just the right
2961 size, nothing will happen as both wxWidgets and Windows check for
2962 this and ignore any attempts to change the window size to the size it
2963 already has - so no WM_SIZE would be sent.
