The document lists several OpenGL constants and functions related to OpenGL extensions and functionality introduced in OpenGL versions 1.5 and above. It includes constants for unsigned integer textures, texture buffers, signed and unsigned normalized textures, geometry shaders, transform feedback, and more. It also lists function prototypes for many basic OpenGL drawing and state functions.
