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_in_out
                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.  Note
      that 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.  Note that
      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.  Note that 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, 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.  Note that
      it returns the minimum Value and the actual Hue and Chroma at which the
      minimum Value was found.
