+ 0 -> 0

+ Since a preview scan is typically made starting from y = 0, but

+ To prevent this, we must always add (at least) 146 to the y
+ offset before it is sent to the scanner. The scanner will then
+ map y = 0 (146) to the first line, y = 1 (147) to the second line,
+ and so on. Any distance that is then measured on the preview scan,
+ can be translated without any discontinuity.
+
+ However, there is one complication: during a preview scan, which
+ normally covers the whole scan area of the scanner, we should _not_
+ add the offset because it will result in a reduced number of lines
+ being returned (the scan height is clamped in
+ pixma_check_scan_param()). Since the frontend has no way of telling
+ that the scan area has been reduced, it would derive an incorrect
+ effective scan resolution, and any position calculations based on
+ this would therefore be inaccurate.
+
+ To prevent this, we don't add the offset in case y = 0, which is
+ typically the case during a preview scan (the scanner effectively
+ adds the offset for us, see above). In that way we keep the
+ linearity and we don't affect the scan area during previews.
