Histogram for source symbols used to estimate symbol probabilities for entropy coding.
Histogram renormed to sum of frequencies being 2^P for use in fast rans coding.
Histogram to depict frequencies of source symbols for rANS compression, based on an ordered set.
Renorm histogram to sum of frequencies = 2^P for use in fast rans coding. Includes estimation of P.
