What about some sort of clone() method, to allow creating a new instance of the
same type of buffer..

so if gst_buffer_create_sub (buf, 0, GST_BUFFER_SIZE (buf)) could return a
buffer that is the same GType as the original buffer, then it would be somewhat
transparent to the receiver of the buffer that a new subbuffer was created.

(On the other hand, it might require any video sink that implements a buffer
pool would have to add a new virtual method to their GstBuffer subclass.. or at
least somehow handle the fact in it's finalize method that the buffer being
finalized could be a clone.. so I guess that doesn't make it completely
transparent.)
