If you update this routine, also update Init below.
Currently, we know of these message classes used in Gargoyle:
(BT)	Complaint: Gargoyle informs the user of a user-initiated problem
(BT)	Error: internal error.  One of Gargoyle's invariants has been broken
(L)	Confirm: Gargoyle asks the user to confirm a guarded operation
(L)	DuringMouse: feedback generated each time the mouse is moved.
(L)	Feedback: an acknowledgement that Gargoyle has done what you asked
(LT)	Show: info that was explicitly requested (e.g. what color is this?)
(LT)	Statistics: Gargoyle prints user requested statistics
(LT)	Warning: Problems during a batch operation, like MergeInterpress
(T)	Typescript: Output that only seems appropriate for the typescript, period.
(L) = send to label.  (B) = send to label and blink.  (T) = send to typescript
There are several places to look in for the Gargoyle control panel:
(1) The file specified in Gargoyle.ControlPanelFile: in the user profile.
(2) The file "[PCedar]<Gargoyle>GargoyleControlPanel.tioga" (useful during development)
(3) The file "[CedarCommon]<FamousFiles>GargoyleControlPanel.tioga"
(4) The file "[PCedar]<FamousFiles>GargoyleControlPanel.tioga"
Use whichever is found first.  Return NIL if none are found.
If that failed, try this:

If you update the router, remember to also correct it in FeedbackLineInGGData above.
