 * Pure virtual base class for the various music/sound engines used in Scumm
 * games. In particular, the iMuse code provides a subclass of this. There are
 * several other subclasses providing music and sound capabilities for
 * several Scumm games.
 * Having this base class for all music engines allows uniform access to the
 * core music/sound functionality, thus simplifying the client code.
 * Instantiated by class Scumm.
