90      follows:
91       0 - scaler input horizontal size
92       1 - input horizontal size for the scaler bypassed
93       2 - REAL_WIDTH without input rotation

101      rotator. Bits 4 and 0 correspond to input and output rotator
102      respectively. If a rotator is present its corresponding bit should be
