 * @param force_ignore_zoc Set to true to completely ignore zones of control.
 * @param allow_teleport   Set to true to consider teleportation abilities.
 * @param viewing_team     Usually the current team, except for "show enemy moves", etc.
 * @param additional_turns The number of turns to account for, in addition to the current.
