* 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.
