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