Canon LiDE 210 with sane-backends 1.0.24 (libsane:amd64 1.0.24-1.1+b1
from debian testing) has problems with 600 dpi gray and lineart.

In 600 dpi gray and lineart the scan is partial and aspect-ratio is
not correct. Vertically only about ¾ of the area is scanned and then
scaled to the area, horizontally all is fine. (So probably the driver
sets the wrong scanline-skip (to small)).

This worked in older versions, at least 1.0.22.

600 dpi Color-scanning works fine, so do preview, 300dpi and 1200 dpi
in all modes.

2400 dpi and 4800 dpi do not work at all, but never did.
