[sane-devel] SOLVED: Fujitsu fi5900c JPG compression fails with ADF Duplex

[m. allan noah]

I have just pushed v137 of the fujitsu backend up to our git repo.
This fixes the bug Wes reported with the fi-5900, and also includes
some updated brightness/contrast code which should fix a bug with the
iX1500.
