New: TerrainMesh plugin (in alpha/beta)

Hi @Holo! Hi @Architex!
we are working hard on MeshSplit and MeshIntersect right now.

I also unfortunately added a bug to the new intersector in the WIP 2 weeks ago. So it’s again not working so well today. Especially for large, planar cuts, it was working very well. I’m hoping to have a fix in this week’s WIP.

Please let me know (feel free to tag me in a new topic) if you have any sample that is not working. At the very least, it will provide some testing ground for improvements to come.
