selectGridLights
selectPointLights over a grid's sources, looking only at the lights near the eye: the same
choice, tie for tie, for a world of thousands of fixed lights that the plain scan would visit
every frame. See lightGrid.ts for why the result is the scan's exactly.
Explained in Hello world.
