;;; State bytes for firefly baddies:
;;;   * Param: The bBadFirefly value specifying the firefly's initial position
;;;     (angle) within its flight path, and its initial facing direction.
;;;     direction and max look-ahead distance.
;;;   * Flags: The bObj::FlipH bit is set if the firefly is facing left, or
;;;     cleared if it is facing right.
;;;   * State1: The number of cooldown frames before the firefly can shoot
;;;     another fireball.
;;;   * State2: The firefly's current angle within its sinusoidal flight
;;;     pattern.
;;;   * State3: Unused.
;;;   * State4: Unused.
