Overload of MinkowskiSum for multiple paths is missing from Clipper2

[olologin]

Hi again,
Clipper1 had:
void MinkowskiSum(const Path& pattern, const Paths& paths, Paths& solution, bool pathIsClosed)

But Clipper2 does not have:
inline Paths64 MinkowskiSum(const Path64& pattern, const Paths64& paths, bool isClosed)

I guess this can work for C++ (Adapted from Clipper1 source, I think nothing changed significantly in MinkowskiSum since then, works for me)

  inline Paths64 MinkowskiSum(const Path64& pattern, const Paths64& paths, bool isClosed)
  {
      Clipper64 c;
      for (size_t i = 0; i < paths.size(); ++i)
      {
          Paths64 tmp = MinkowskiSum(pattern, paths[i], isClosed);
          c.AddSubject(tmp);
          if (isClosed)
          {
              Paths64 tmp2(1);
              tmp2[0].resize(paths[i].size());
              for (size_t j = 0; j < paths[i].size(); ++j)
              {
                  tmp2[0][j] = Point64(paths[i][j].x + pattern[0].x, paths[i][j].y + pattern[0].y);
              }
              c.AddClip(tmp2);
          }
      }
      Paths64 solution;
      c.Execute(ClipType::Union, FillRule::NonZero, solution);
      return solution;
  }
