pathgl/documentation/svg.md

A webgl renderer for data visualization, motion graphics and explorable explanations.

Pathgl implements a scenegraph with svg semantics.
Documented here is a list of discrepancies between the pathGL virtualDOM
and the [SVG 1.1 Specification](http://www.w3.org/TR/SVG/).
Expect this list to get shorter and eventually disappear completely.
