So you are also missing dashoffset in 0.5.1, we may need to update

Thanks for the report @lslzl3000. This bug (introduced in 0.5.1) was recently fixed in the Three repo and I've just applied the fix here too.

I've also added a dashOffset control to the example at: https://vasturiano.github.io/three-fatline/example/fat-lines/ to ensure that it's fixed.

Make sure to use v0.5.2. 👍
