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).

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.
