* 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.

* For the default windowBits of 15 and memLevel of 8, this function returns
* a close to exact, as well as small, upper bound on the compressed size.
* They are coded as constants here for a reason--if the #define's are
* changed, then this function needs to be changed as well. The return
* value for 15 and 8 only works for those exact settings.
* For the default windowBits of 15 and memLevel of 8, this function returns a
* close to exact, as well as small, upper bound on the compressed size. This
* is an expansion of ~0.03%, plus a small constant.
*
* For any setting other than those defaults for windowBits and memLevel,
* the value returned is a conservative worst case for the maximum expansion
* resulting from using fixed blocks instead of stored blocks, which deflate
* can emit on compressed data for some combinations of the parameters.
* For any setting other than those defaults for windowBits and memLevel, one
* of two worst case bounds is returned. This is at most an expansion of ~4% or
* ~13%, plus a small constant.
*
* This function could be more sophisticated to provide closer upper bounds for
* every combination of windowBits and memLevel. But even the conservative
* upper bound of about 14% expansion does not seem onerous for output buffer
* allocation.
* Both the 0.03% and 4% derive from the overhead of stored blocks. The first
* one is for stored blocks of 16383 bytes (memLevel == 8), whereas the second
* is for stored blocks of 127 bytes (the worst case memLevel == 1). The
* expansion results from five bytes of header for each stored block.
*
* The larger expansion of 13% results from a window size less than or equal to
* the symbols buffer size (windowBits <= memLevel + 7). In that case some of
* the data being compressed may have slid out of the sliding window, impeding
* a stored block from being emitted. Then the only choice is a fixed or
* dynamic block, where a fixed block limits the maximum expansion to 9 bits
* per 8-bit byte, plus 10 bits for every block. The smallest block size for
* which this can occur is 255 (memLevel == 2).
*
* Shifts are used to approximate divisions, for speed.

This is a heavily modified and shrinked version of zlib 1.2.3
- Removed comments from zlib.h
- Removed gzip/zip archive I/O
- Removed infback.c
- Added Assimp #idefs to exclude it if not needed
- Disabled debug macros in zutil.h
Assimp itself does not use the compression part yet, so
it needn't be compiled (trees.c, deflate.c, compress.c).
Currently these units are just used by assimp_cmd.
