     ARGUMENTS
          ccc       Specifies the CCC.  Note that the CCC's Client
                    White Point and White Point Adjustment procedures
                    are ignored.

          chroma    Specifies the chroma at which to find maximum
                    Value (MaxV).

          colors_return
                    Returns nsamples of color specifications in
                    XcmsTekHVC such that the Chroma is the maximum
                    attainable for the Value and Hue.  The white point
                    associated with the returned color specification
                    is the Screen White Point.  The value returned in
                    the pixel member is undefined.

          color_return
                    Returns the maximum Chroma along with the actual
                    Hue and Value (MaxC), maximum Value along with the
                    Hue and Chroma (MaxV), color specification in
                    XcmsTekHVC for the maximum Chroma, the Value at
                    which that maximum Chroma is reached and actual
                    Hue (MaxVC) or minimum Value and the actual Hue
                    and Chroma (MinL) at which the maximum Chroma
                    (MaxC and MaxVC), maximum Value (MaxV), or minimum
                    Value (MinL) was found.  The white point
                    associated with the returned color specification
                    is the Screen White Point.  The value returned in
                    the pixel member is undefined.

          hue       Specifies the Hue in which to find the maximum
                    Chroma (MaxC and MaxVC), maximum Value (MaxV), the
                    maximum Chroma/Value samples (MaxVSamples), or the
                    minimum Value (MinL).

          nsamples  Specifies the number of samples.

          value     Specifies the Value in which to find the maximum
                    Chroma (MaxC) or minimum Value (MinL).

     DESCRIPTION
          The XcmsTekHVCQueryMaxC function, given a Hue and Value,
          determines the maximum Chroma in TekHVC color space
          displayable by the screen.  It returns the maximum Chroma
          along with the actual Hue and Value at which the maximum
          Chroma was found.

          The XcmsTekHVCQueryMaxV function, given a Hue and Chroma,
          determines the maximum Value in TekHVC color space
          displayable by the screen.  It returns the maximum Value and
          the actual Hue and Chroma at which the maximum Value was
          found.

          The XcmsTekHVCQueryMaxVC function, given a Hue, determines
          the maximum Chroma in TekHVC color space displayable by the
          screen and the Value at which that maximum Chroma is
          reached.  It returns the maximum Chroma, the Value at which
          that maximum Chroma is reached, and the actual Hue for which
          the maximum Chroma was found.

          The XcmsTekHVCQueryMaxVSamples returns nsamples of maximum
          Value, the Chroma at which that maximum Value is reached,
          and the actual Hue for which the maximum Chroma was found.
          These sample points may then be used to plot the maximum
          Value/Chroma boundary of the screen's color gamut for the
          specified Hue in TekHVC color space.

          The XcmsTekHVCQueryMinV function, given a Hue and Chroma,
          determines the minimum Value in TekHVC color space
          displayable by the screen.  It returns the minimum Value and
          the actual Hue and Chroma at which the minimum Value was
          found.
