SDL precise scrolling can sometimes produce values greater than 1 or less than -1. On the wire, the value is encoded as a 16-bit fixed-point number. Previously, the range was interpreted as [-1, 1], using 1 bit for the integral part (the sign) and 15 bits for the fractional part. To support larger values, interpret the range as [-16, 16] instead, using 5 bits for the integral part and 11 bits for the fractional part (which is more than enough).
