-// Conversions between RGB and CIE XYZ
-//
-// RGB to XYZ:
-//
-//     Given a set of chromaticities, c, and the luminance, Y, of the RGB
-//     triple (1,1,1), or "white", RGBtoXYZ(c,Y) computes a matrix, M, so
-//     that multiplying an RGB value, v, with M produces an equivalent
-//     XYZ value, w.  (w == v * M)
-// 
-//     If we define that
-// 
-//        (Xr, Yr, Zr) == (1, 0, 0) * M
-//        (Xg, Yg, Zg) == (0, 1, 0) * M
-//        (Xb, Yb, Zb) == (0, 0, 1) * M
-//        (Xw, Yw, Zw) == (1, 1, 1) * M,
-// 
-//     then the following statements are true:
-// 
-//        Xr / (Xr + Yr + Zr) == c.red.x
-//        Yr / (Xr + Yr + Zr) == c.red.y
-// 
-//        Xg / (Xg + Yg + Zg) == c.red.x
-//        Yg / (Xg + Yg + Zg) == c.red.y
-// 
-//        Xb / (Xb + Yb + Zb) == c.red.x
-//        Yb / (Xb + Yb + Zb) == c.red.y
-// 
-//        Xw / (Xw + Yw + Zw) == c.red.x
-//        Yw / (Xw + Yw + Zw) == c.red.y
-// 
-//        Yw == Y.
-// 
-// XYZ to RGB:
-// 
-//     YYZtoRGB(c,Y) returns RGBtoXYZ(c,Y).inverse().
-// 
-// Warning:
-// 
-//     It would seem that RGBtoXYZ() and XYZtoRGB() are all you need
-//     to convert RGB values with one set of primary and white point
-//     chromaticities into perceptually equivalent RGB values with
-//     different primary and white point chromaticities:
-// 
-//         M44f M = RGBtoXYZ (chromaticities1, Y1) *
-//                  XYZtoRGB (chromaticities2, Y2);
-// 
-//     However, this simple conversion does not account for white point
-//     adaptation, and produces undesirable results.  The proper thing
-//     to do is to perform a Bradford or a von Kries transform, which
-//     moves the white point of the original color space to the white
-//     point of the destination color space, dragging other colors with
-//     it in a sensible fashion.
