00027 // Description : A class object that manages a single asynchronous
00028 //               audio load request.  This works in conjunction with
00029 //               the Loader class defined in pgraph, or really with
00030 //               any AsyncTaskManager.  Create a new AudioLoadRequest,
00031 //               and add it to the loader via load_async(), to begin
00032 //               an asynchronous load.
