  *  Used to test decoding SkImages out of order.
  *  e.g.
  *  SkImage* imageA = decoder.createFrameAtIndex(0);
  *  // supply more (but not all) data to the decoder
  *  SkImage* imageB = decoder.createFrameAtIndex(laterFrame);
  *  imageB->preroll();
  *  imageA->preroll();
  *
  *  This results in using the same ImageDecoder (in the ImageDecodingStore) to
  *  decode less data the second time. This test ensures that it is safe to do
  *  so.
  *
  *  @param fileName File to decode
  *  @param bytesForFirstFrame Number of bytes needed to return an SkImage
  *  @param laterFrame Frame to decode with almost complete data. Can be 0.
