Constant VP8_TOKEN_PARTITIONS 

const VP8_TOKEN_PARTITIONS: c_int = _; // 3i32

VP8’s token partitions, eight, the most it has: a client decoding in software spreads a frame across them, as across H.264’s slices, where one leaves it on one thread. They cost nothing measurable: at 1080p text, a game frame and dense text code within 0.1% of the bytes and 0.02 dB of one partition while scrolling, and within 2% still.
