/*
 * XXX scancap make this sort of obsolete:
 *
 * Some comments about the values in the scan_io struct:
 *
 * All user-changeable values have minimum and maximum values for
 * specific scanner types and are rejected by the special drivers if
 * they are not in range. For values in the range, the driver selects
 * the next physically possible setting for the particular scanner.
 * So it is good practice to issue a SCIOCGET after a SCIOCSET to see
 * what the driver has chosen.
 *
 * Brightness and contrast default to 100 (%) but scanners may support
 * higher and/or lower values, though the maximum value is 255.
 * velocity is the scan speed and defaults to 100 (%), only slower
 * values may be possible.
