+ * QObject Reference Counts Terminology
+ * ------------------------------------
+ *
+ *  - Returning references: A function that returns an object may
+ *  return it as either a weak or a strong reference.  If the reference
+ *  is strong, you are responsible for calling QDECREF() on the reference
+ *  when you are done.
+ *
+ *  If the reference is weak, the owner of the reference may free it at
+ *  any time in the future.  Before storing the reference anywhere, you
+ *  should call QINCREF() to make the reference strong.
+ *
+ *  - Transferring ownership: when you transfer ownership of a reference
+ *  by calling a function, you are no longer responsible for calling
+ *  QDECREF() when the reference is no longer needed.  In other words,
+ *  when the function returns you must behave as if the reference to the
+ *  passed object was weak.
