3727 NB: there used to be some code here which set the initial size of the

3729 specified. This was wrong because wxWidgets programs often assume
3730 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3731 it. To see why, you should understand that Windows sends WM_SIZE from
3732 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3733 from some base class ctor and so this WM_SIZE is not processed in the
3734 real class' OnSize() (because it's not fully constructed yet and the
3735 event goes to some base class OnSize() instead). So the WM_SIZE we
3736 rely on is the one sent when the parent frame resizes its children
3737 but here is the problem: if the child already has just the right
3738 size, nothing will happen as both wxWidgets and Windows check for
3739 this and ignore any attempts to change the window size to the size it
3740 already has - so no WM_SIZE would be sent.
