3609 NB: there used to be some code here which set the initial size of the

3611 specified. This was wrong because wxWidgets programs often assume
3612 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3613 it. To see why, you should understand that Windows sends WM_SIZE from
3614 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3615 from some base class ctor and so this WM_SIZE is not processed in the
3616 real class' OnSize() (because it's not fully constructed yet and the
3617 event goes to some base class OnSize() instead). So the WM_SIZE we
3618 rely on is the one sent when the parent frame resizes its children
3619 but here is the problem: if the child already has just the right
