                (InsertUndo.positions): New field.
                (InsertUndo.redo): Update the undo positions.
                (InsertUndo.undo): Fetch the undo positions.
                (Mark): New class. Layer of indirection to allow Positions
                to be GC'ed while we still hold references to the Mark.
                (RemoveUndo.len): New field.
                (RemoveUndo.positions): New field.
                (RemoveUndo.RemoveUndo): Fetch undo positions.
                (RemoveUndo.redo): Re-fetch positions and string.
                (RemoveUndo.undo): Update undo positions.
                (StickyPosition.mark): New field.
                (StickyPosition.offset): Removed field.
                (StickyPosition.StickyPosition): Create new Mark. Register
                Position in queueOfDeath. Update reference count on mark.
                (StickyPosition.getOffset): Return offset stored in mark.
                (StickyPosition.setOffset): Removed unneeded method.

                (positions): Removed field.
                (queueOfDeath): New field. Used for GCing the positions.
                (StringContent): Initialize queueOfDeath.
                (createPosition): Lazily create marks vector.
                (garbageCollect): New helper method. Collects positions
                to be GCed and updates their marks.
                (getChars): Fixed bounds check.
                (getPositionsInRange): When v == null, create new Vector,
                otherwise use v. Store UndoPosRefs in vector.
                (getString): Added comment about bug in RI.
                (insertString): Use new helper method for replacing the array.

                (remove): Use new helper method for replacing the array.
                Correctly update positions.
                (replace): New helper method for growing or patching the array.
                (updateUndoPositions): Implemented. Updates the positions
                for undo/redo operations.
