caged / svg-to-png.js

Convert SVG's to PNGs. This works OK if the SVG's styles are inline. The SVG element must contain an xmlns attribute. Webkit also requires you specify a font size on `text` elements.
var svg = document.getElementById('graph'),
xml = new XMLSerializer().serializeToString(svg),
data = "data:image/svg+xml;base64," + btoa(xml),
img = new Image()
img.setAttribute('src', data)
document.body.appendChild(img)

Seqables are odd in Clojure. Some functions auto-`seq`, some don't.
