 You can always call FT_Set_Char_Size(face, s, s). Then, you can get the
rest of the transformation with:
                 T = R x S
        INV(R) x T = S

        where S = | s  0 |
                  | 0  s |
        and
              s = art_affine_expansion(T);

  This should produce similar results... more or less :)
