     * 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.
