See implementation by @devongovett — http://gist.github.com/424839

maybe this can help: http://github.com/millermedeiros/SVGParser/blob/master/com/millermedeiros/geom/SVGArc.as - it follows the spec and has comments of each step so it should be easier to follow..

and method "getCurves" on Arc Class: http://github.com/millermedeiros/SVGParser/blob/master/com/millermedeiros/geom/Arc.as - it convert the arc into multiple quadratic bezier curves (1 curve per each 45 degrees)

@millermedeiros
Thank you. That looks interesting, I'll look into it more when I get a chance.
