Part of #722 (volumetrics epic).

Existing particle content can't change, so two tiers:

For every particle: soft particles (fade where sprites meet geometry) and lighting through the froxel grid (sun, shadow, local lights).
Opt-in volumetric injection: smoke / steam-like particle systems (large, soft, low alpha) inject density into the froxel grid instead of drawing sprites. Viewer-side setting, heuristic, local only; may misjudge stylised particles, hence opt-in.
