+ it. To see why, you should understand that Windows sends WM_SIZE from
+ inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
+ from some base class ctor and so this WM_SIZE is not processed in the
+ real class' OnSize() (because it's not fully constructed yet and the
+ event goes to some base class OnSize() instead). So the WM_SIZE we
+ rely on is the one sent when the parent frame resizes its children
+ but here is the problem: if the child already has just the right
+ size, nothing will happen as both wxWindows and Windows check for
+ this and ignore any attempts to change the window size to the size it
+ already has - so no WM_SIZE would be sent.
