Operator of cast to non-const reference is declared deprecated to produce compiler warning if used (usually implicitly). OCCT code is updated to avoid that cast, occurring when function accepting non-const reference to handle is called with handle to derived type. For that, local variable of argument type is passed instead, and down-cast is used to get it to desired type after the call. A few occurrences of use of uninitialized variable are corrected.
