119     * @brief RIFF specific classes and definitions
120     *
121     * The Resource Interchange File Format (RIFF) is a generic tree-structured
122     * meta-format which stores data in so called "chunks". It can be compared
123     * to XML, but in contrast to XML, RIFF is entirely binary encoded, that is
124     * not ASCII based. RIFF is used as basis for many file formats like AVI,
125     * WAV, DLS and of course the Gigasampler file format. ;-)
126     *
127     * RIFF chunks can be seen as containers for data. There are two distinct
128     * types of chunks:
129     *
130     * - @e ordinary @e chunks are the leafs of the data tree which encapsulate
131     *   the actual data of the file (i.e. the sample data of a .wav file)
132     *
133     * - @e list @e chunks are the nodes of the data tree which hold an
134     *   arbitrary amount of subchunks (can be both, list chunks and/or ordinary
135     *   chunks)
