"bgCompendiumTemplate"
Use the tileset definitions for fgtiles on this bgtileset

"summit" and "rock"
These are both patched versions of vanilla tilesets. rock now has properly colored inner corners, and summit now has single tile variants.

"arkedRuinesTileset"
Uses a different template than vanilla, also my first finished custom tileset.
Based on one of Starbound's ark tilesets, but not a copy of it.
