Polymer icon set not scaling with size

[M4N0JKUM4R]

As you can check the screenshot of the URL: iron-iconset I am not sure if the icons are meant to be scaled with ratio like 2x, 3x such as in Fontawesome, Gylphicons. Current icon set looks distorted.

This is not a demo of the icons, it's a demo of how you can create a custom iconset (in this case using PNG files):

You're probably looking for iron-icons. The iron-icons demo is missing from the left navigation due to a catalog bug, but you can find it here:

These icons are SVG, so they scale smoothly.
