* sanei/sanei_constrain_value.c:

if checked option is a range and the value is out of
          range the value is now corrected to the minimum or maximum
          allowed value and SANE_INFO_INEXACT is set.
          The old version returned with an error. This caused problems
          when the value was a little bit out of range because of rounding
          errors.
