Returns true if there was an attempt at reading bit past the end of the buffer. Doesn't set br->eos_ flag.

Move to next position, or NULL. Should not be called if !VP8LRefsCursorOk().

Return true if output is finished

Difference of each component, mod 256.

return approximate write position (in bits)

Initialize the structure as empty. Must be called before any other use. Returns false in case of version mismatch

Should always be called, to initialize the structure. Returns false in case of version mismatch. WebPPictureInit() must have succeeded before using th

Return the prefetched bits, so they can be looked up.

For jumping over a number of bits in the bit stream when accessed with VP8LPrefetchBits and VP8LFillBitWindow.

fast 0..255 * 0..255 => 0..255 rounded multiplication

Simulate block coding, but only record statistics. Note: no need to record the fixed probas.

returns 1 if "a*b*c + add" has no negative terms/factors and doesn't overflow

Returns (int)floor(log2(n)). n must be > 0.

Mostly used to reduce code size + readability
