/**
* Native bindings to the EXT_sRGB extension.
*
* The sRGB color space is based on typical (non-linear) response of the human eye. It has been standardized by the International Electrotechnical
* Commission (IEC) as IEC 61966-2-1. The transfer function of sRGB roughly corresponds to a power function with a gamma of 2.2.
*
* FRAMEBUFFERS
*
* OpenGL assumes framebuffer color components are stored in a linear color space. In particular, framebuffer blending is a linear operation.
*
* This extension adds a framebuffer capability for sRGB framebuffer update and blending. When blending is disabled but the new sRGB updated mode is
* enabled (assume the framebuffer supports the capability), high-precision linear color component values for red, green, and blue generated by fragment
* coloring are encoded for sRGB prior to being written into the framebuffer. When blending is enabled along with the new sRGB update mode, red, green,
* and blue framebuffer color components are treated as sRGB values that are converted to linear color values, blended with the high- precision color
* values generated by fragment coloring, and then the blend result is encoded for sRGB just prior to being written into the framebuffer.
*
* TEXTURES
*
* Conventional texture formats assume a linear color space. So for a conventional internal texture format such as GL_RGB8, the 256 discrete values for
* each 8-bit color component map linearly and uniformly to the [0,1] range.
