I don't think so, would you really type in 65535 instead of 255?  If you don't 
use downscale(), the output would always be broken.

Maybe QUANTUM needs to be always 32 bit, no matter what the color channel 
depth is.

I don't want to have to define variables of different type depending on what 
channel you are working with.  That is just too much of a pain to use.
