Fix assertion due to adjustment value being zero

Browse Source 
wx3 on OSX has changed how the mouse wheel delta is calculated.  Prior
to wx3, it was simply set to 1 so the wheel rotaion value was simply
increments of one.

With wx3, higher resolution devices (like touchpads) are supported so
the value for wheel rotation can be a fraction of the delta, so it is
possible to pass a zero value to the NumericConverter::Adjust() method.
Therefore, the method just returns in this case.
