Polyon rendering glitch

[springmeyer]

I noticed in the demo instance that @ebrelsford put up at https://mltdemo.stamen.com that there is some glitch art in Antarctic:

@ebrelsford how recently where the MLTs used in the demo encoded? Can you make sure to re-encode them with a java encoder version that includes #193? Is the glitch still present?

I also noticed there are some subtle tile boundary artifacts in the center of Africa:

I'm almost positive these should be fixed by re-encoding after #193.

I encoded these this morning so they should include the changes from #193 but I can try again, there's a chance I was on a wrong branch.

On main I rebuilt the cli (./gradlew cli) and am running encode.jar on the input MVTs, seeing the same glitches.

Okay, thanks for checking.
