This extension is always added to the GL_EXTENSIONS extension string for the current GL context, regardless of if it's supported by the h/w driver. The extension itself will be handled by GLES_trace (eventually), when GLES_trace is not enabled, it'll result to a no-op. If the h/w implementation has this extension, we'll call that version instead of our dummy version. Change-Id: Ie5dd3387c4d45cd5ed5f03b73bda6045620a96bc
