SVG not rendered?

[novito]

I have a problem when trying to convert to PNG an HTML that has SVG. Basically the SVG are not showing up.

Here is the HTML: https://gist.github.com/novito/9518767

And here is the CSS: https://gist.github.com/novito/9518788

The way I am creating the PNG is:

require 'imgkit' kit = IMGKit.new(File.new('160x600.html')) kit.to_file('test.png')

Any ideas why the stars might not be rendering? Is SVG supported at all?
