code: public Matrix3x2f scale(Vector2fc xy, Matrix3x2f dest) {
          return scale(xy.x(), xy.y(), dest);
      }
docs: Apply scaling to this matrix by scaling the base axes by the given <code>xy</code> factors
  and store the result in <code>dest</code>.
  <p>
  If <code>M</code> is <code>this</code> matrix and <code>S</code> the scaling matrix,
  then the new matrix will be <code>M * S</code>. So when transforming a
  vector <code>v</code> with the new matrix by using <code>M * S * v</code>, the scaling will be applied first!
  
  @param xy
  the factors of the x and y component, respectively
  @param dest
  will hold the result
  @return dest
