Fixed issues with z-index by hiding the y-sort behind a flag.

I like this change, but it's unfortunate that it's a breaking change.

I personally feel like the right call might be to remove the y-sorting for a 0.10.1 release and then do this in the main branch / for an eventual 0.11. I think that would work out better for most people. Very few should be relying on it right now, and it seems to be broken in some cases anyhow.

Yeah, I was thinking maybe it was okay to sneak by, but anyone using TilemapRenderSettings would probably get a little upset.
