[Vorbis-dev] OGG loads as a naked file, but not if embedded in an IFF.

I already have a library for parsing Blorb files.  There is no need for 
libsndfile to support it.  A Blorb file contains AIFFs, MODs, and OGGs as 
chunks.  Generally what the Blorb library does is check the index chunk 
for the sound clip desired and return a filepointer to the beginning of 
that clip.  It seems to me that it would make no difference to libsndfile 
if the file pointer (well, handle) points to a naked file or a portion of 
a container file (a Blorb file).  This doesn't bother libsndfile if I'm 
loading an AIFF the same way.
