3. The 4:4:0 (h1v2) fancy (smooth) chroma upsampling algorithm in the
decompressor now uses a similar bias pattern to that of the 4:2:2 (h2v1) fancy
chroma upsampling algorithm, rounding up or down the upsampled result for
-alternate pixels rather than always rounding down. This ensures that the final
-result will be similar regardless of whether a 4:2:2 JPEG image is rotated or
-transposed prior to decompression (in the frequency domain) or after
-decompression (in the spatial domain.)

4. Fixed an integer overflow and subsequent segfault that occurred when
attempting to compress or decompress images with more than 1 billion pixels
