+   * State Transition Flags
+   *
+   * These flags indicate the various states that requests may transition
+   * through as they are being loaded.  These flags are mutually exclusive.
+   *
+   * For any given request, onStateChange is called once with the STATE_START
+   * flag, zero or more times with the STATE_TRANSFERRING flag or once with the
+   * STATE_REDIRECTING flag, and then finally once with the STATE_STOP flag.
+   * NOTE: For document requests, a second STATE_STOP is generated (see the
+   * description of STATE_IS_WINDOW for more details).
+   *
+   * STATE_START
+   *   This flag indicates the start of a request.  This flag is set when a
+   *   request is initiated.  The request is complete when onStateChange is
+   *   called for the same request with the STATE_STOP flag set.
+   *
+   * STATE_REDIRECTING
+   *   This flag indicates that a request is being redirected.  The request
+   *   passed to onStateChange is the request that is being redirected.  When a
+   *   redirect occurs, a new request is generated automatically to process the
+   *   new request.  Expect a corresponding STATE_START event for the new
+   *   request, and a STATE_STOP for the redirected request.
+   *
+   * STATE_TRANSFERRING
+   *   This flag indicates that data for a request is being transferred to an
+   *   end consumer.  This flag indicates that the request has been targeted,
+   *   and that the user may start seeing content corresponding to the request.
+   *
+   * STATE_NEGOTIATING
+   *   This flag is not used.
+   *
+   * STATE_STOP
+   *   This flag indicates the completion of a request.  The aStatus parameter
+   *   to onStateChange indicates the final status of the request.

+   * State Type Flags
+   *
+   * These flags further describe the entity for which the state transition is
+   * occuring.  These flags are NOT mutually exclusive (i.e., an onStateChange
+   * event may indicate some combination of these flags).
+   *
+   * STATE_IS_REQUEST
+   *   This flag indicates that the state transition is for a request, which
+   *   includes but is not limited to document requests.  (See below for a
+   *   description of document requests.)  Other types of requests, such as
+   *   requests for inline content (e.g., images and stylesheets) are
+   *   considered normal requests.
+   *
+   * STATE_IS_DOCUMENT
+   *   This flag indicates that the state transition is for a document request.
+   *   This flag is set in addition to STATE_IS_REQUEST.  A document request
+   *   supports the nsIChannel interface and its loadFlags attribute includes
+   *   the nsIChannel::LOAD_DOCUMENT_URI flag.
+   * 
+   *   A document request does not complete until all requests associated with
+   *   the loading of its corresponding document have completed.  This includes
+   *   other document requests (e.g., corresponding to HTML <iframe> elements).
+   *   The document corresponding to a document request is available via the
+   *   DOMWindow attribute of onStateChange's aWebProgress parameter.
+   *
+   * STATE_IS_NETWORK
+   *   This flag indicates that the state transition corresponds to the start
+   *   or stop of activity in the indicated nsIWebProgress instance.  This flag
+   *   is accompanied by either STATE_START or STATE_STOP, and it may be
+   *   combined with other State Type Flags.
+   *
+   *   Unlike STATE_IS_WINDOW, this flag is only set when activity within the
+   *   nsIWebProgress instance being observed starts or stops.  If activity
+   *   only occurs in a child nsIWebProgress instance, then this flag will be
+   *   set to indicate the start and stop of that activity.
+   *
+   *   For example, in the case of navigation within a single frame of a HTML
+   *   frameset, a nsIWebProgressListener instance attached to the
+   *   nsIWebProgress of the frameset window will receive onStateChange calls
+   *   with the STATE_IS_NETWORK flag set to indicate the start and stop of
+   *   said navigation.  In other words, an observer of an outer window can
+   *   determine when activity, that may be constrained to a child window or
+   *   set of child windows, starts and stops.
+   *
+   * STATE_IS_WINDOW
+   *   This flag indicates that the state transition corresponds to the start
+   *   or stop of activity in the indicated nsIWebProgress instance.  This flag
+   *   is accompanied by either STATE_START or STATE_STOP, and it may be
+   *   combined with other State Type Flags.
+   *
+   *   This flag is similar to STATE_IS_DOCUMENT.  However, when a document
+   *   request completes, two onStateChange calls with STATE_STOP are
+   *   generated.  The document request is passed as aRequest to both calls.
+   *   The first has STATE_IS_REQUEST and STATE_IS_DOCUMENT set, and the second
+   *   has the STATE_IS_WINDOW flag set (and possibly the STATE_IS_NETWORK flag
+   *   set as well -- see above for a description of when the STATE_IS_NETWORK
+   *   flag may be set).  This second STATE_STOP event may be useful as a way
+   *   to partition the work that occurs when a document request completes.
