/**
 * Native bindings to the EXT_texture_sRGB extension.
 * 
 * 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.
 * 
 * The sRGB color space is based on typical (non-linear) monitor characteristics expected in a dimly lit office.  It has been standardized by the
 * International Electrotechnical Commission (IEC) as IEC 61966-2-1. The sRGB color space roughly corresponds to 2.2 gamma correction.
 * 
 * This extension adds a few new uncompressed and compressed color texture formats with sRGB color components.
 * 
 * Promoted to core in {@link GL21 OpenGL 2.1}.
