SYNTAX
      Status XcmsCIELuvQueryMaxC(ccc, hue_angle, L_star, color_return)
            XcmsCCC ccc;
            XcmsFloat hue_angle;
            XcmsFloat L_star;
            XcmsColor *color_return;

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

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

      Status XcmsCIELuvQueryMinL(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*u*v* 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) or maximum lightness (MaxL).

DESCRIPTION
      The XcmsCIELuvQueryMaxC function, given a hue angle and lightness, finds
      the point of maximum chroma displayable by the screen.  Note that it
      returns this point in CIE L*u*v* coordinates.

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

      The XcmsCIELuvQueryMaxLC function, given a hue angle, finds the point of
      maximum chroma displayable by the screen.  Note that it returns this
      point in CIE L*u*v* coordinates.

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