[sane-devel] Lexmark experimental backend

[Fred Odendaal]

Much better. I was able to do a scan. However, the scan had blue streaks 
down the middle. It also started the scan too early (you can see the 
area off the glass) and the rewind went too far (you could hear the scan 
head hitting the end).  I can create logfiles if you want. Just let me 
know what debugging info you need.

regards,
Fred O.
