[Toon-members] Identity bug with -

[Georg Klein]

Matrix<> m999(3,3);
  for(int i=0; i<3; i++)
    for(int j=0; j<3; j++)
      m999[i][j] = 999;

cout << "m999: " << endl;
cout << m999 << endl;
cout << "Identity - 999 " << endl;
cout << Identity - m999 << endl;


Gives:

m999:
999 999 999
999 999 999
999 999 999

Identity - 999
998 999 999
999 998 999
999 999 998

The latter is incorrect...
