The WEBGL_debug_shaders extension is part of the WebGL API and exposes a method to debug shaders from privileged contexts.

This extension is not directly available to websites as the way of how the shader is translated may uncover personally-identifiable information to the web page about the kind of graphics card in the user's computer.

WebGL extensions are available using the WebGLRenderingContext.getExtension() method. For more information, see also Using Extensions in the WebGL tutorial.

WEBGL_debug_shaders.getTranslatedShaderSource()

Returns the translated shader source.
