3027 NB: there used to be some code here which set the initial size of the
3028 window to the client size of the parent if no explicit size was
3029 specified. This was wrong because wxWindows programs often assume
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
