3034 NB: there used to be some code here which set the initial size of the

3036 specified. This was wrong because wxWidgets programs often assume
3037 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3038 it. To see why, you should understand that Windows sends WM_SIZE from
3039 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3040 from some base class ctor and so this WM_SIZE is not processed in the
3041 real class' OnSize() (because it's not fully constructed yet and the
3042 event goes to some base class OnSize() instead). So the WM_SIZE we
3043 rely on is the one sent when the parent frame resizes its children
3044 but here is the problem: if the child already has just the right
