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

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

       colors_return
		 Returns nsamples of color specifications in Xcm
		 sTekHVC such that the Chroma is the maximum
		 attainable for the Value and Hue.  The white
		 point associated with the returned color speci
		 fication 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 maxi
		 mum 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 dis
       playable 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 dis
       playable 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 dis
       playable by the screen.	It returns the minimum Value and
       the actual Hue and Chroma at which the minimum Value was
       found.
