Subject: Tidy up Context and ProcessContext interfaces (ProcessContext only
 lives on as a useful type).

-/** Context of a process() call.
+/** Context of a process() call (the audio context).
  *
- * This is used to pass whatever information a GraphObject might need to
- * process in the audio thread, e.g. the available thread pool, sink for
- * events (generated in the audio thread, not user initiated events), etc.
- *
- * Note the distinction between nframes and start/end.  If transport speed
- * != 1.0, end-start != nframes (though currently that is never the case, it
- * may be in the future with sequencerey things).
+ * This class currently adds no functionality to Context, but the
+ * separate type is useful for writing functions that must only
+ * be run in the audio context (the function taking a ProcessContext
+ * parameter makes this clear, and makes breaking the rules obvious).
