/**
 *  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);
 *  draw(imageB);
 *  draw(imageA);
 *
 *  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.
