        // Notes about Data:
        // - Each data block in the samples contains a GIF header
        // - Each GIF header contains an application extension: http://www.vurdalakov.net/misc/gif/application-extension
        // - Each GIF doesn't always stretch to the end of the data
        // - Remaining data seems to be padded as 0x00 (typically 8 bytes)
        // - GIF data is fully formed and may be copied to a standalone file
