I believe at minimum those numbers have to be unique. However, although not essential it is really nice for human understanding to make sure those numbers are contiguous for a given device driver. Thus, I would suggest you go ahead and bump (I would suggest by three to give plenty of room for future cairo device expansion) the Qt device numbers. And in the future when somebody implements the next device driver let's remember to start its device numbers at least three above the transformed qt device number range since the number of qt devices is bound to expand over the years as well.
