Converts RGB to XYZ Note from original author: The following performs a "gamma correction" specified by the sRGB color space. sRGB is defined by a canonical definition of a display monitor and has been standardized by the International Electrotechnical Commission (IEC 61966-2-1). The nonlinearity of the correction is designed to make the colors more perceptually uniform. This color space has been adopted by several applications including Adobe Photoshop and Microsoft Windows color management. OpenGL is agnostic on its RGB color space, but it is reasonable to assume it is close to this one.
