In the referenced example, the referenced SVG looks blurry and pixelated instead of sharp and crisp.

We need to investigate why the SVG file is not rendered. The transform uses scale3d(x,y,1) So the transformation is still 2D.

Dirk, which example are you referring to? The examples at your url look fine to me in Safari Nightly @ r172901. Can you upload a minimized testcase in case the referenced page changes?

As another note (which I forgot), you need to click on the shape and move the mouse. This will scale your shape.
