3608 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3609 it. To see why, you should understand that Windows sends WM_SIZE from
3610 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3611 from some base class ctor and so this WM_SIZE is not processed in the
3612 real class' OnSize() (because it's not fully constructed yet and the
3613 event goes to some base class OnSize() instead). So the WM_SIZE we
3614 rely on is the one sent when the parent frame resizes its children
3615 but here is the problem: if the child already has just the right
3616 size, nothing will happen as both wxWidgets and Windows check for
3617 this and ignore any attempts to change the window size to the size it
3618 already has - so no WM_SIZE would be sent.
