+1.6 progress callback without doubles
+
+ The progress callback was introduced way back in the days and the choice to
+ use doubles in the arguments was possibly good at the time. Today the doubles
+ only confuse users and make the amounts less precise. We should introduce
+ another progress callback option that take precedence over the old one and
+ have both co-exist for a forseeable time until we can remove the double-using
+ one.
