Do we need the prefix and do we need this to happen in AnimationPlayer? I'd
rather stringize the result of sequenceNumber() somewhere in the inspector code.

Done.

     unsigned sequenceNumber() const { return m_sequenceNumber; }
 
     static bool hasLowerPriority(AnimationPlayer* player1, AnimationPlayer* player2)
     {
         return player1->sequenceNumber() < player2->sequenceNumber();
     }
