cc: Rebalance tree priorities in SMOOTHNESS_TAKES_PRIORITY
Instead of only rasterizing pending NOW tiles before active
EVENTUALLY tiles, rasterize ALL pending tiles before active
EVENTUALLY tiles.
After rasterizing all pending NOW tiles, we should activate
very soon and won't need the active EVENTUALLY tiles anyway.
