            Implement extension entry points and remove EXTENSIONS enum
            https://bugs.webkit.org/show_bug.cgi?id=40316
    
            Added support for ensuring that a particular OpenGL extension is
            enabled.

            Implement extension entry points and remove EXTENSIONS enum
            https://bugs.webkit.org/show_bug.cgi?id=40316
    
            Implemented WebGLRenderingContext's getSupportedExtensions and
            getExtensions entry points, and, to verify them, added support for
            the first specified WebGL extension, OES_texture_float. This
            extension is now advertised in the Chromium and WebKit ports when
            the underlying hardware supports it.
    
            The new OES_texture_float test in the WebGL conformance suite
            verifies the allocation and population of floating point textures,
            and their use as render targets. However, because this extension
            is optional, it is not easily testable with a layout test; there
            is only one set of expectations for a given test, and two would be
            needed, one when the extension is available and one when it is not.
    
            Tested with the oes-texture-float.html WebGL conformance test in
            Chromium and WebKit on Mac OS X on hardware that supports the
            extension. Also verified with a configuration that does not
            advertise the extension that this same test passes.
