|* With a paragraph-anchored fly it's absolutely possible that
|* the anchor reacts to changes of the fly. To this reaction the fly must
|* certainly react too. Sadly this can lead to oscillations; for example the
|* fly wants to go down therefore the content can go up - this leads to a
|* smaller TextFrame thus the fly needs to go up again whereby the text will
|* get pushed down...
|* To avoid such oscillations, a small position stack is built. If the fly
|* reaches a position which it already had once, the action is stopped.
|* To not run into problems, the stack is designed to hold five positions.
|* If the stack flows over, the action is stopped too.
|* Cancellation leads to the situation that the fly has a bad position in
|* the end. In case of cancellation, the frame is set to automatic top
|* alignment to not trigger a 'big oscillation' when calling from outside
|* again.
