3023 NB: there used to be some code here which set the initial size of the
3024 window to the client size of the parent if no explicit size was
3025 specified. This was wrong because wxWidgets programs often assume
3026 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3027 it. To see why, you should understand that Windows sends WM_SIZE from
3028 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3029 from some base class ctor and so this WM_SIZE is not processed in the
3030 real class' OnSize() (because it's not fully constructed yet and the
3031 event goes to some base class OnSize() instead). So the WM_SIZE we
3032 rely on is the one sent when the parent frame resizes its children
3033 but here is the problem: if the child already has just the right
3034 size, nothing will happen as both wxWidgets and Windows check for
3035 this and ignore any attempts to change the window size to the size it
