  // This function is just here so that we have references to these API
  // functions in the build. If we don't reference them, they get LTO'd out and
  // then emscripten gets fails to build the javascript support library. These
  // all will eventually be actually used when we implement proper image
  // support, at which time we can just remove this function entirely.
