Picks this frame's sources from the sim: flames and embers only from the active front (recently
ignited cells, by intensity), smoke from the front (dark for heavy woody fuel, white for wet or light
fuel) plus faint wisps from smouldering and freshly burnt cells. Writes the per-cell texture too.
Deterministic: depends only on the sim state.
