this is a weird definition of log2() for which log2(1) = 1, log2(2) = 2, log2(4) = 3 as required by the specification. fast(?) implementation from stb

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

The next two functions are responsible for calculating the prediction. When the bits per sample is >16 we need to use 64-bit integer arithmetic becau

Retrieves a variable number of bits from the input stream. Markers will not be read into the input bit buffer. Instead, an infinite number of all 1's

take a -128..127 value and stbi__clamp it and convert to 0..255
