I think you can do both of these just as easily from the outside with Iter.  I'd
be totally fine with these as helper standalone functions in this file that
operate on a SkTDynamicHash.  Just seems we don't need them as methods.

Yup, just had that discussion here. Done.

+            }
+            ++index;
