I've now tested five printers from three manufacturers; the output is 
visibly improved with all of them, with better contrast and tonal range 
across the board.  

As an added bonus, when using the manufacturer ICC profiles the outputs 
are finally consistent with each other!

So I've commited the change.

But since this change represents a significant change in output, I added 
an option to revert to the old behavior, defaulting to off.  If the 
user enables "LegacyDyesubGamma", the dyesub driver will revert to the 
old behavior.

...I still need to document this change in the NEWS file though.
