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).

       colorsinout
                 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.

       colorreturn
                 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.
