47611: Handle Waiting Outlaw
Type 12: the outlaw in the duel before he draws. He wanders about the screen, changing direction a random number of times (the count in IX+10), and at the end of the last move he draws his gun. If the player moves or fires before then he draws at once. He is hit if the crosshair is on him when the player fires.
