Sorry for the late interference. isPointInStroke is implemented in WebKit and Blink for quite some time and should be in release versions already. No objection from this side :)

I would suggest a third argument:

	optional CanvasFillRule fillRule = "nonzero"

As we have for fill. (This is implemented in WebKit and Blink as well.)
