/*
 * A battler may be in one of four positions on the field. The first bit determines
 * what side the battler is on, either the player's side or the opponent's side.
 * The second bit determines what flank the battler is on, either the left or right.
 * Note that the opponent's flanks are drawn corresponding to their perspective, so
 * their right mon appears on the left, and their left mon appears on the right.
 * The battler ID is usually the same as the position, except in the case of link battles.
