Using deprecated method getPathSegAtLength

[lannymcnie]

The recent Chrome update (62.0.3202) has run-time errors, specifically:

Uncaught TypeError: this.pathElement.getPathSegAtLength is not a function
    at t.getPathPoint (thirdparty.min.js:3)
    at i.characterLayout (thirdparty.min.js:3)
    at i.layout (thirdparty.min.js:3)
    at i.fontLoaded (thirdparty.min.js:3)
    at thirdparty.min.js:3

It looks like getPathSegAtLength is deprecated, along with some other methods:

In SVG 2 the getPathSegAtLength() and createSVGPathSeg* methods were removed and the pathLength property and the getTotalLength() and getPointAtLength() methods were moved to SVGGeometryElement.

Our team is looking at patching it locally, and will submit a PR if successful.

a PR would be awesome ! Some people are still using this plugin :)
