P0-A8: Part 815: Art, Improvements

The terrain smoothing is going very well.

I had some issues with getting the terrain to smooth properly across terrain boundaries, I had to make some significant changes to how my solution worked.

However, I have solved this issue, although my solution isn’t hugely efficient.

There are still some minor bugs to fix and features to add. I will probably not integrate this solution with the main project now, but I do want a proof of concept working.
