NAME
	RefreshGList -- Refresh (redraw) a chosen number of gadgets.

    SYNOPSIS
	RefreshGList( Gadgets, Window, Requester, NumGad )
		      A0       A1      A2         D0

	VOID RefreshGList( struct Gadget *, struct Window *,
		struct Requester *, WORD );

    FUNCTION
	Refreshes (redraws) gadgets in the gadget list starting
	from the specified gadget.  At most NumGad gadgets are redrawn.
	If NumGad is -1, all gadgets until a terminating NULL value
	in the NextGadget field is found will be refreshed, making this
	routine a superset of RefreshGadgets().

	The Requester parameter can point to a Requester structure.  If
	the first gadget in the list has the GTYP_REQGADGET flag set, the
	gadget list refers to gadgets in a requester and the pointer
	must necessarily point to a window.  If these are not the gadgets
	of a requester, the requester argument may be NULL.

	Be sure to see the RefreshGadgets() function description, as this
	function is simply an extension of that.

    INPUTS
	Gadgets = pointer to the first in the list of gadgets wanting
	    refreshment
	Window = pointer to the window containing the gadget or its requester
	Requester = pointer to a requester (ignored if Gadget is not attached
	    to a Requester).
	NumGad  = maximum number of gadgets to be refreshed.  A value of -1
	  will cause all gadgets to be refreshed from gadget to the
	  end of the list.  A value of -2 will also do this, but if 'Gadgets'
	  points to a Requester Gadget (GTYP_REQGADGET) ALL gadgets in the
	  requester will be refreshed (this is a mode compatible with v1.1
	  RefreshGadgets().)

    RESULT
	None
