Should this be exposed on the DOM SVGAngle interface? Not in the spec. ATM
(AFAICS), but I suspect you'll still get unitType === 5 if you access
SVGMarkerElement.orientAngle for instance?

Some rudimentary tests for that (and the conversions) would probably be good (in
either case.)

Will raise this in the WG, but I think we should still go ahead with it.
Added.
