TopOverride
A settlement's surface over the terrain's top voxel (a path, a yard), per column: an absolute palette slot, or 0 to keep the terrain's own. Either a function of the (coarse) column, or the same as data: a Uint8Array of slots indexed x + z width, which crosses to a worker (see topOverrideData).
ROLE_COUNT
Number of roles; voxel values run from 1 to this, so a host allocates this many palette slots.
