  Pass GL_VERSION info through ANGLE's GL_RENDERER string
  
  Chrome needs ANGLE to pass through the underlying driver vendor and
  version, which cannot always be determined by the SystemInfo library.
  This is done by construction GL_RENDERER in the frontend through
  combining GL_VENDOR, GL_RENDERER, and GL_VERSION from the backends.
  
  Example changes are in the doc:
