Thanks for submitting this PR!

Could you remove the extra background elements from the 2nd and 3rd logos,
And also run them through something like svgomg.

I'm not sure how we would be wanting to go about merging multiple logos variants, maybe @paulmelnikow has some ideas about this?

On that note though, i would be fine with just merging the 3rd logo for now () until we get more info on adding the extra variants:
(liberapay3.svg → liberapay.svg) Could either update this PR or open a secondary PR

Examples:
Logo1:

Logo2:

Logo3:

It's a work in progress. I'm running the variants by people at liberapay/liberapay.com#1103 to pick just one.

SVG has been optimized and variants removed. Ready for review.

Thanks for the changes,
Logo looks good to me:

Merged!

Quoting @paulmelnikow:

Deploys usually happen every 1–3 weeks. Thaddée [@espadrine], who has limited time on this project, is the only sysadmin. He's working on giving me access to deploy and logs, but doing so is complicated because the hosting account (and maybe the servers too) are shared with other services he runs.

Edit: it has been almost 2 months since the last commit (Mar 25) so i'm hoping there will be one soon.
