    Move transfer functions to 16 bits.
    
    This means that in 'deep' modes, we sample them in 257 places
    (0000,0100,....ff00,ffff) rather than 256 (00,01,...ff), and
    in 16 bits rather than 8. We also interpolate them on reading.
    
    This in turn increases the size of the data put into the clist.
