/* ----------------------------------------------------------------<Prolog>-
Name: sflcomp.h
Title: Compression functions
Package: Standard Function Library (SFL)
Written: 1991/05/20 iMatix SFL project team <sfl@imatix.com>
Revised: 1997/09/08
Synopsis: Various compression/decompression functions. The LZ-type
algorith (LZRW1/KH) was originally written by Kurt Haenen
<ghgaea8@blekul11> and made portable by P. Hintjens. This
is a reasonable LZ/RLE algorithm, very fast, but about 30%
less efficient than a ZIP-type algorithm in terms of space.
The RLE algorithms are better suited to compressing sparse
data. The nulls variant is specifically tuned to data that
consists mostly of binary zeroes. The bits variant is
tuned for compressing sparse bitmaps.
