40 * Width of the body of a map using PERSEC characters per sector.
42 * One row shows WORLD_X/2 sectors, separated by one space. Requires
43 * WORLD_X/2 * (PERSEC+1) - 1 characters.
45 * Every other row is indented so that the center of the first sector
46 * is aligned with the space separating the first two sectors in the
47 * adjacent rows. For odd PERSEC, that's (PERSEC+1)/2 additional
48 * characters. For even PERSEC, it's either PERSEC/2 or PERSEC/2 + 1,
49 * depending on whether we align the character left or right of the
50 * center with the space (the map will look rather odd either way).
52 * We need one more character for the terminating zero.
