[whatwg] Canvas Path.addPath SVGMatrix not optimal?

[Dirk Schulze]

Hi, 

I just looked at the definition of Path.addPath[1]:

    void addPath(Path path, SVGMatrix? transformation);

SVGMatrix is nullable but can not be omitted all together. Why isn’t it 
optional as well? I think it should be optional, especially because creating an 
SVGMatrix at the moment means writing:

    var matrix = 
document.createElementNS('http://www.w3.org/2000/svg','svg').createSVGMatrix();

Greetings,
Dirk
