Has there been any consideration of adding keystone correction, and not just deskewing? Unfortunately I have two cheaper (all in ones, rather than dedicated scanners)-the Brother MFC-6920DW and the Epson Workforce WF-7610, and both, even with perfectly flat pieces of paper, distort pretty heavily on one side. I'm guessing it would be a pain in the butt to implement, but it would be a really great feature to have. Could code be swiped from some of the other GPL image correction software out there?
