3030 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3031 it. To see why, you should understand that Windows sends WM_SIZE from
3032 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3033 from some base class ctor and so this WM_SIZE is not processed in the
3034 real class' OnSize() (because it's not fully constructed yet and the
3035 event goes to some base class OnSize() instead). So the WM_SIZE we
3036 rely on is the one sent when the parent frame resizes its children
3037 but here is the problem: if the child already has just the right
3038 size, nothing will happen as both wxWidgets and Windows check for
3039 this and ignore any attempts to change the window size to the size it
3040 already has - so no WM_SIZE would be sent.
