// CSpriteNotifyObj class
//
// This is a class of pure virtual functions with no data.  It is used
// by sprite objects to make notification callbacks.  A user of the CSprite
// class can derive an object from CSpriteNotifyObj and pass a pointer to this
// derived class object to the sprite object for notification calls.
// Just like OLE's IClientSite interface really.
