- uncoupled the stream sources from the low level implementation. The entire setup had the stream sources depend on the SoundStream class, severely limiting reusability. This was changed that there is one SoundStream class that uses the StreamSources as mere data source that has no knowledge and no connection to the underlying system, similar to how the MIDI system works. With this there are only 3 top level music classes left - MIDIStreamer, StreamSong and CDSong.
Also made the decode_vorbis function in DUMB a function pointer so that the library does not depend on high level code and can just ignore the vorbis case if no supported.
