This method is actually deprecated (and so are the "non-scaled" ones above).

Let's remove the GetTouchSlopInDips() then so people don't start using it.  

I don't believe the fling velocity-related methods are yet in use, but we should
probably remove those as well (separately, I can do that).  That or re-implement
them in terms of device scale factor and the scaled queries.
