A SANE backend (the driver can now be used with xsane, xscanimage, and the other SANE frontends), and fixes for a memory leak and a bug which caused garbled output when odd scan area dimensions were selected.
Fixes two fairly serious scan quality bugs: dark areas will no longer have a mottled appearance, and calibration corrections will no longer be broken for scans that don't start at the left edge of the scan area.
Functional EPP mode, enabling of Lineart mode (emulated in software), scans using parameters entered from the command line to bypass the interactive UI, and fixes for problems with nibble-mode calibration hangs and scanning in nibble mode only on some systems if lp had been invoked previously.
