--- Comment #26 from Peter Hutterer <peter.hutterer at who-t.net> ---
Finally starting to pick this up again. I have some complaints about slow
movements not being right, so I wonder if dropping deceleration is the right
idea. Simple patch to try out, it may be the right step, please let me know.

        return factor * TP_MAGIC_SLOWDOWN;
 }
