Artifact when offsetting an SVG path

[JDMCreator]

Related to #140. I am using normalize-svg-path to convert an SVG path to a series of Bezier curves. This way, I am able to use the impressive .offset() function from Bezier.js. However, it seems that there is no way for the function to take into account that the offset bezier curve is part of a series of curves, resulting in artifacts. Is it possible to set the starting point of the offset curves?

I have created a JSFiddle to help you understand what the problem is: https://jsfiddle.net/wfyd832j/1/
