       WebGLRenderingContext getExtension API to enable the extension. For example, if
       the extension were OES_texture_float, then the extension would be fetched and
       enabled with a call to getExtension("OES_texture_float")

       Per WebGL convention, the 'GL_' prefix is dropped from all extension and enum
       names, and the 'gl' prefix dropped from, and capitalization adjusted of, all
       function names.
