DC14: Set Facing Flags
Used by the routines at UpdatePlayerLegs and ChooseDirection.
Sets the sprite of the legs of the player from the direction. Bits 6 and 7 of the flags (to flip the sprite) and bit 3 of the type (to choose between the two sets of sprites) are taken from the table at PlayerSpriteTable, which is turned around by two places when the view is rotated.
Input
