I'm just saying you could be in a situation where you are dealing with
code values in the 0-1023 range (this is common when dealing with SDI
sources, for example), so it is is more convenient to read/write 10
bit values rather than 16 bit values. Convenient, and also common
enough that I'd think it'd be good to keep the 10 bit pix formats
around.
