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.  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) minimum Value (MinL)

       color_return
                 Returns the maximum Chroma along with the actual Hue and
                 Value (MaxC), at which the maximum Chroma (MaxC and MaxVC),
                 maximum Value (MaxV), or was found.  The white point associ-
                 ated with the returned color specification is the Screen
                 White Point.  The value returned in the pixel member is unde-
                 fined.  maximum Value (MaxV), the maximum Chroma/Value sam-
                 ples (MaxVSamples), or the minimum Value (MinL)

       hue       Specifies the Hue in which to find the maximum Chroma (MaxC
                 and MaxVC),.

       nsamples  Specifies the number of samples.

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

       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.
