    1&2 = v, V, u, U, d, D, Ud, or uD, as follows:
      v = vertical line for full height.
      u = upper half of vertical line.
      d = downward (lower) half of vertical line.
    3&4 = h, H, l, L, r, R, Lr, or lR, as follows:
      h = horizontal line for full width.
      l = left half of horizontal line.
      r = right half of horizontal line.
    In all cases, an upper-case letter means a double or heavy line.
