When using non-default constructors for the API parameter classes, vector arguments like coordinates and hints are copied at least once (twice when passed as lvalue arguments). Enable perfect forwarding of BaseParameter arguments and pass-by-value in the constructor that uses the argument. This ensures we copy at most once (zero for rvalue arguments).
