Style nits: Usually the name of a method should be VerbNoun(), so maybe
GetNumberOfCopies()?

Besides, please put it in a newer version (by updating label struct above, and
also adding [version=XXX] tag.)

You probably also want to notify pepper-dev@chromium.org (or
pepper-team@google.com if you want to have internal discussion) about your
proposed interface change.

I'm unsure of this change. Please check and let me know if something should be
changed.

[Nikhil, 2014/07/16 13:52:55]

Done.
