SYNTAX
      Status XcmsCIELabQueryMaxC(ccc, hue_angle, L_star, color_return)
            XcmsCCC ccc;
            XcmsFloat hue_angle;

      Status XcmsCIELabQueryMaxL(ccc, hue_angle, chroma, color_return)
            XcmsCCC ccc;
            XcmsFloat hue_angle;
            XcmsFloat chroma;
            XcmsColor *color_return;

      Status XcmsCIELabQueryMaxLC(ccc, hue_angle, color_return)
            XcmsCCC ccc;
            XcmsFloat hue_angle;
            XcmsColor *color_return;

      Status XcmsCIELabQueryMinL(ccc, hue_angle, chroma, color_return)
            XcmsCCC ccc;
            XcmsFloat hue_angle;
            XcmsFloat chroma;
            XcmsColor *color_return;

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 lightness (MaxL)
                or minimum lightness (MinL).

      color_return
                Returns the CIE L*a*b* coordinates of maximum chroma (MaxC and
                MaxLC), maximum lightnes (MaxL), or minimum lightness (MinL)
                displayable by the screen for the given hue angle and lightness
                (MaxC), hue angle and chroma (MaxL and MinL), or hue angle
                (MaxLC).  The white point associated with the returned color
                specification is the Screen White Point.  The value returned in
                the pixel member is undefined.

      hue_angle Specifies the hue angle in degrees at which to find maximum
                chroma (MaxC and MaxLC), maximum lightness (MaxL), or minimum
                lightness (MinL).

      L_star    Specifies the lightness (L*) at which to find maximum chroma
                (MaxC).

DESCRIPTION
      The XcmsCIELabQueryMaxC function, given a hue angle and lightness, finds
      the point of maximum chroma displayable by the screen.  It returns this
      point in CIE L*a*b* coordinates.

      The XcmsCIELabQueryMaxL function, given a hue angle and chroma, finds the
      point in CIE L*a*b* color space of maximum lightness (L*) displayable by
      the screen.  It returns this point in CIE L*a*b* coordinates.  An
      XcmsFailure return value usually indicates that the given chroma is
      beyond maximum for the given hue angle.

      The XcmsCIELabQueryMaxLC function, given a hue angle, finds the point of
      maximum chroma displayable by the screen.  It returns this point in CIE
      L*a*b* coordinates.

      The XcmsCIELabQueryMinL function, given a hue angle and chroma, finds the
      point of minimum lightness (L*) displayable by the screen.  It returns
      this point in CIE L*a*b* coordinates.  An XcmsFailure return value
      usually indicates that the given chroma is beyond maximum for the given
      hue angle.
