I've updated the behavior for the double spinner according to option 4.

Consequences of this approach are:
 - The wrapping behavior of the double spinner is not the same as for the integer spinner, even for all-integer values.
 - Going over the limit with one Spinner arrow, and going back with the other arrow, will generally not result in the previous value.
