For simplicity and short typing. JIRA issue: CORE-19469 - Replace "virtual HRESULT STDMETHODCALLTYPE m" with "STDMETHOD(m)" (m is a method name). - Replace "virtual t STDMETHODCALLTYPE m" with "STDMETHOD_(t, m)" (t is a type. m is a method name). - Use "override" keyword as possible. - CDefView should inherit IShellView3 due to override CreateViewWindow3 method. - Fix CDefView::CreateViewWindow3 (parameter prcView is const RECT *, not LPRECT).
