3722 NB: there used to be some code here which set the initial size of the

3724 specified. This was wrong because wxWidgets programs often assume
3725 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3726 it. To see why, you should understand that Windows sends WM_SIZE from
3727 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3728 from some base class ctor and so this WM_SIZE is not processed in the
3729 real class' OnSize() (because it's not fully constructed yet and the
3730 event goes to some base class OnSize() instead). So the WM_SIZE we
3731 rely on is the one sent when the parent frame resizes its children
3732 but here is the problem: if the child already has just the right
3733 size, nothing will happen as both wxWidgets and Windows check for
3734 this and ignore any attempts to change the window size to the size it
3735 already has - so no WM_SIZE would be sent.
