Is there any reason for limiting Path2D.addPath() and CanvasPattern.setTransform() to a 2D matrix?

That seems a bit weird Path2D can do less than the context's subpath, and for patterns, it would be possible to apply a 3D transform to it, when using the context's subpath (by setting the transform after the path declaration), once again making Path2D less powerful.

Good point @Kaiido! I'll do that. I believe that the implementation in chromium already supports that.

Is this still being pursued?

It is not. Core graphics is not capable so it was nixed by webkit.
