3221 specified. This was wrong because wxWidgets programs often assume
3222 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3223 it. To see why, you should understand that Windows sends WM_SIZE from
3224 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3225 from some base class ctor and so this WM_SIZE is not processed in the
3226 real class' OnSize() (because it's not fully constructed yet and the
3227 event goes to some base class OnSize() instead). So the WM_SIZE we
3228 rely on is the one sent when the parent frame resizes its children
3229 but here is the problem: if the child already has just the right
3230 size, nothing will happen as both wxWidgets and Windows check for
3231 this and ignore any attempts to change the window size to the size it
3232 already has - so no WM_SIZE would be sent.
