Hi, Stef.

I appreciate you working on this. I just tested the latest commit. I'm
sorry to say that changes in genesys files sources did not improve scan
results. Color is still incorrect in the same way as before.

I made sure I used the most recent commit isolated from the install from
my system. I used xscanimage under ~/sane-install/bin.
