Aren't you looking for
[[
arcTo(x1, y1, x2, y2, radiusX, radiusY, rotation)
]]
http://www.w3.org/TR/2dcontext2/#dom-context-2d-arcto
It's not clear to me that it's properly supported yet however
https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/arcTo
So I don't think we should move it into the first version of the 2d
context api unfortunately.
