Hm, hadn't thought about that, could be an issue.  Can you give me
simple examples of when it would make sense, for both of these, to have
increments, and not just a range ?

Anyway, the increment would then probably be treated as a multiplier,
instead of an accumulator value, no ?

Not sure yet where the information of what the increment does should be
stored; maybe a fourth GValue holding an enum ?
