3014           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3015           it. To see why, you should understand that Windows sends WM_SIZE from
3016           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3017           from some base class ctor and so this WM_SIZE is not processed in the
3018           real class' OnSize() (because it's not fully constructed yet and the
3019           event goes to some base class OnSize() instead). So the WM_SIZE we
3020           rely on is the one sent when the parent frame resizes its children
3021           but here is the problem: if the child already has just the right
3022           size, nothing will happen as both wxWindows and Windows check for
3023           this and ignore any attempts to change the window size to the size it
3024           already has - so no WM_SIZE would be sent.
