3032 NB: there used to be some code here which set the initial size of the
3033 window to the client size of the parent if no explicit size was
3034 specified. This was wrong because wxWidgets programs often assume
3035 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3036 it. To see why, you should understand that Windows sends WM_SIZE from
3037 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3038 from some base class ctor and so this WM_SIZE is not processed in the
3039 real class' OnSize() (because it's not fully constructed yet and the
3040 event goes to some base class OnSize() instead). So the WM_SIZE we
3041 rely on is the one sent when the parent frame resizes its children
3042 but here is the problem: if the child already has just the right
3043 size, nothing will happen as both wxWidgets and Windows check for
3044 this and ignore any attempts to change the window size to the size it
