Supermode is an option to improve global rendering and get more details.
After years of use, we received a lot of request to get a Super User pass to enhance SVG.
We give people a lot of pass, but few of them shared a link (sadly :) about PICSVG on Twitter (Picsvg Tweets), Facebook, or others social network.
That's why, to stay fair, if you need one , please just share a link somewhere about Picsvg.com and send us an email in order to see it.
Or just link to us on your blog, a forum...
Last but no least : number of pass are limited...
Or simply use Picsvg.com without this Pass, it works great too.
