[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();

I would even argue that SVGMatrix should just be optional.

Greetings,
Dirk
