The WEBGL_compressed_texture_s3tc_srgb extension is part of the WebGL API and exposes four S3TC compressed texture formats for the sRGB colorspace.
The WEBGL_debug_renderer_info extension is part of the WebGL API and exposes two constants with information about the graphics driver for debugging purposes.
The WEBGL_debug_shaders extension is part of the WebGL API and exposes a method to debug shaders from privileged contexts.
The WEBGL_depth_texture extension is part of the WebGL API and defines 2D depth and depth-stencil textures.

The WEBGL_multi_draw extension is part of the WebGL API and allows to render more than one primitive with a single function call. This can improve a WebGL application's performance as it reduces binding costs in the renderer and speeds up GPU thread time with uniform data.
The WebGLActiveInfo interface is part of the WebGL API and represents the information returned by calling the WebGLRenderingContext.getActiveAttrib() and WebGLRenderingContext.getActiveUniform() methods.
The WebGLBuffer interface is part of the WebGL API and represents an opaque buffer object storing data such as vertices or colors.
The WebGLContextEvent interface is part of the WebGL API and is an interface for an event that is generated in response to a status change to the WebGL rendering context.
The WebGLFramebuffer interface is part of the WebGL API and represents a collection of buffers that serve as a rendering destination.
The WebGLProgram is part of the WebGL API and is a combination of two compiled WebGLShaders consisting of a vertex shader and a fragment shader (both written in GLSL).
The WebGLQuery interface is part of the WebGL 2 API and provides ways to asynchronously query for information. By default, occlusion queries and primitive queries are available.

The WebGLUniformLocation interface is part of the WebGL API and represents the location of a uniform variable in a shader program.
The WebGLVertexArrayObject interface is part of the WebGL 2 API, represents vertex array objects (VAOs) pointing to vertex array data, and provides names for different sets of vertex data.
