buckets have an odd artifact when large #173

I noticed this while working on another issue, tested it on the currently live version of the sim (v1.6.0), and it exists there as wall. There is a noticeable artifact that sometimes appears at the edges of the bucket, especially when displayed on a large screen. Here's a screen shot - the artifact appears above the right side of the bucket.

I tried this on all browsers on my Windows machine, which are Chrome, Firefox, MS Edge, and MS IE11. The artifact is only seen on Chrome. The version is 60.0.3112.90 (Official Build) (64-bit).

I tried modifying the elliptical curve that makes up the top of the shape to be a little less than the full 180 degrees, and that seems to have worked. It now looks like this:
