Providing for the Upstream

I have submitted my work to the upstream through github.

https://github.com/google/zopfli/issues/104

 I thought it would be best practice to first show my finding to the community for them to comment on the benefits and cons that I don't know about. Unfortunately, even 4 days after posting no one has responded yet. I assume even if I had made a pull request, the same thing would have happened at this point in time as no new pull requests were answered either.

For the sake of time though, if the work had been accepted, I would have had to went through their guidelines for contributing. Which follows a Google Individual Contributor License Agreement (CLA). The following is stated:

Before you contribute

Before we can use your code, you must sign the Google Individual Contributor License Agreement (CLA), which you can do online. The CLA is necessary mainly because you own the copyright to your changes, even after your contribution becomes part of our codebase, so we need your permission to use and distribute your code. We also need to be sure of various other things—for instance that you'll tell us if you know that your code infringes on other people's patents. You don't have to sign the CLA until after you've submitted your code for review and a member has approved it, but you must do it before we can put your code into our codebase. Before you start working on a larger contribution, you should get in touch with us first through the issue tracker with your idea so that we can help out and possibly guide you. Coordinating up front makes it much easier to avoid frustration later on.

Code reviews

All submissions, including submissions by project members, require review. We use Github pull requests for this purpose.

The small print

Contributions made by corporations are covered by a different agreement than the one above, the Software Grant and Corporate Contributor License Agreement.

 I followed their suggestion of:

But since they have not answered me yet, I was not able to continue with the signing of the CLA.
