The Silent Cartographer with 32x co-op enemies (484 actors) went from 53
to about 97 fps on the Linux PC, with the same game and the same picture:
cluster list removals start where the reference was put, full data arrays
are not walked again, object lighting keeps each cluster's drawn lights
and passes over far ones without their distance, the per-texture profile
timer only runs while something reads it, and the renderer binds streams
once per draw, caches its texture, target and shader lookups, and no
longer makes Mesa's GL thread wait on large uploads or visibility tests.
