I think the most important thing here is that we now let users know that
"offset" is not a byte count. This also fixes some small typos, e.g.
"weights" was used in the docstring instead of "positions".
To avoid making API changes, this does not fix a few weird things I
noticed in the Java API. For example, there is a redundant "count"
argument in methods that take an array. Also some methods do not
provide an "offset" argument, which is not consistent with C++.
