Tilecover returns adjacent / touching tiles about orb

The Tile -> Bound -> 4 Tiles problem is expected. A tile is "closed" on 2 sides and "open" on the others (I think it's the top and left that are closed). Said another way, a point on a boundary or intersection of tiles should only be in 1 tile, or things get more complicated.

For example the point (0, 0) is at the intersection of 4 tiles, but is only in 1.

A bound however is closed on all 4 sides. 2 sides (edges, lines) are in the bound but not in the original tile. Extra tiles are add to cover those lines.

For the second question about intersecting bounds. I think it's the same issue, the new bound represents the boundary, a line, not empty.

Not sure what the solution is, maybe update the bound to support open and closed boundaries?

Oh, I completely forgot about this issue.

Yes, having an option to specify open/closed boundaries sounds like it could help. But I have no idea how much of the code base would be affected by this ;)
