ClientToWindowSize() doesn't work correctly with minimized windows on MSW

I've noticed that using ClientToWindowSize() or WindowToClientSize() yields wrong results when the window is minimized on MSW because minimized windows on MSW have a size of 0/0 so the following calculation done by ClientToWindowSize()

    const wxSize diff(GetSize() - GetClientSize());

yields a difference of whatever size is in GetSize() and this difference is then added to the size passed to ClientToWindowSize() which obviously leads to completely wrong dimensions returned by ClientToWindowSize().

The fact that ClientToWindowSize() doesn't work correctly when the window is minimized also has the implications that functions like SetMinClientSize() etc. don't work correctly with minimized windows on MSW...

So I'm wondering if this is this something that should be fixed or are those functions simply not supposed to be used on minimized windows on MSW?
