+ * Terminology (assuming power law, "gamma", encodings):
+ * "screen" gamma: a power law imposed by the output device when digital
+ * samples are converted to visible light output. The EOTF - volage to
+ * luminance on output.
+ *
+ * "file" gamma: a power law used to encode luminance levels from the input
+ * data (the scene or the mastering display system) into digital voltages.
+ * The OETF - luminance to voltage on input.
+ *
+ * gamma "correction": a power law matching the **inverse** of the overall
+ * transfer function from input luminance levels to output levels. The
+ * **inverse** of the OOTF; the correction "corrects" for the OOTF by aiming
+ * to make the overall OOTF (including the correction) linear.
+ *
+ * It is important to understand this terminology because the defined terms are
+ * scattered throughout the libpng code and it is very easy to end up with the
+ * inverse of the power law required.
+ *
+ * Variable and struct::member names:
+ * file_gamma OETF how the PNG data was encoded
+ *
+ * screen_gamma EOTF how the screen will decode digital levels
+ *
+ * -- not used -- OOTF the net effect OETF x EOTF
+ * gamma_correction the inverse of OOTF to make the result linear
+ *
+ * All versions of libpng require a call to "png_set_gamma" to establish the
+ * "screen" gamma, the power law representing the EOTF. png_set_gamma may also
+ * set or default the "file" gamma; the OETF. gamma_correction is calculated
+ * internally.
+ *
+ * The earliest libpng versions required file_gamma to be supplied to set_gamma.
+ * Later versions started allowing png_set_gamma and, later, png_set_alpha_mode,
+ * to cause defaulting from the file data.
+ *
+ * PNGv3 mandated a particular form for this defaulting, one that is compatible
+ * with what libpng did except that if libpng detected inconsistencies it marked
+ * all the chunks as "invalid". PNGv3 effectively invalidates this prior code.
+ *
+ * Behaviour implemented below:
+ * translate_gamma_flags(gamma, is_screen)
+ * The libpng-1.6 API for the gamma parameters to libpng APIs
+ * (png_set_gamma and png_set_alpha_mode at present). This allows the
+ * 'gamma' value to be passed as a png_fixed_point number or as one of a
+ * set of integral values for specific "well known" examples of transfer
+ * functions. This is compatible with PNGv3.

Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:

Polynomials over GF(2) are represented in binary, one bit per coefficient,
- with the lowest powers in the most significant bit. Then adding polynomials
+ with the lowest powers in the most significant bit. Then adding polynomials
is just exclusive-or, and multiplying a polynomial by x is a right shift by
- one. If we call the above polynomial p, and represent a byte as the
+ one. If we call the above polynomial p, and represent a byte as the
polynomial q, also with the lowest power in the most significant bit (so the
- byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
+ byte 0xb1 is the polynomial x^7+x^3+x^2+1), then the CRC is (q*x^32) mod p,
where a mod b means the remainder after dividing a by b.
This calculation is done using the shift-register method of multiplying and
- taking the remainder. The register is initialized to zero, and for each
+ taking the remainder. The register is initialized to zero, and for each
incoming bit, x^32 is added mod p to the register if the bit is a one (where
- x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
- x (which is shifting right by one and adding x^32 mod p if the bit shifted
- out is a one). We start with the highest power (least significant bit) of
- q and repeat for all eight bits of q.
+ x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by x
+ (which is shifting right by one and adding x^32 mod p if the bit shifted out
+ is a one). We start with the highest power (least significant bit) of q and
+ repeat for all eight bits of q.
- The first table is simply the CRC of all possible eight bit values. This is
- all the information needed to generate CRCs on data a byte at a time for all
- combinations of CRC register values and incoming bytes. The remaining tables
- allow for word-at-a-time CRC calculation for both big-endian and little-
- endian machines, where a word is four bytes.

+ * bits or less.
+ *
+ * Analysis: The longest fixed codes are a length code of 8 bits plus 5
+ * extra bits, for lengths 131 to 257. The longest fixed distance codes are
+ * 5 bits plus 13 extra bits, for distances 16385 to 32768. The longest
+ * possible fixed-codes length/distance pair is then 31 bits total.
+ *
+ * sym_buf starts one-fourth of the way into pending_buf. So there are
+ * three bytes in sym_buf for every four bytes in pending_buf. Each symbol
+ * in sym_buf is three bytes -- two for the distance and one for the
+ * literal/length. As each symbol is consumed, the pointer to the next
+ * sym_buf value to read moves forward three bytes. From that symbol, up to
+ * 31 bits are written to pending_buf. The closest the written pending_buf
+ * bits gets to the next sym_buf symbol to read is just before the last
+ * code is written. At that time, 31*(n - 2) bits have been written, just
+ * after 24*(n - 2) bits have been consumed from sym_buf. sym_buf starts at
+ * 8*n bits into pending_buf. (Note that the symbol buffer fills when n - 1
+ * symbols are written.) The closest the writing gets to what is unread is
+ * then n + 14 bits. Here n is lit_bufsize, which is 16384 by default, and
+ * can range from 128 to 32768.
+ *
+ * Therefore, at a minimum, there are 142 bits of space between what is
+ * written and what is read in the overlain buffers, so the symbols cannot
+ * be overwritten by the compressed data. That space is actually 139 bits,
+ * due to the three-bit fixed-code block header.
+ *
+ * That covers the case where either Z_FIXED is specified, forcing fixed
+ * codes, or when the use of fixed codes is chosen, because that choice
+ * results in a smaller compressed block than dynamic codes. That latter
+ * condition then assures that the above analysis also covers all dynamic
+ * blocks. A dynamic-code block will only be chosen to be emitted if it has
+ * fewer bits than a fixed-code block would for the same set of symbols.
+ * Therefore its average symbol length is assured to be less than 31. So
+ * the compressed data for a dynamic block also cannot overwrite the
+ * symbols from which it is being constructed.
