Should this be a syncable pref? I don't know the answer for sure, but the
majority of the prefs below are unsyncable, so I think we should discuss this.

[je_julie(Not used), 2015/01/31 07:25:35]

There is no specific reason using SYNCABLE_PREF. 
I refered to kAcceptLanguages case.
I think there is no problem with UNSYNCABLE_PREF for animation policy.
