These files are intended to replace the old files on: /historic-computers/png/PNGCRUSH/ I was testing how big changes different window sizes in pngcrush create to file sizes. The very first pngcrush conversion I made was only done with window size 32. The differences were not that good and it took a lot of computing time. I was also skeptical about the bugs in pngcrush because the version I tested was one of the first. Now I've recompiled the latest pngcrush version (1.5.3), updated it with libpng version 1.0.9 and zlib version 1.1.3 and set TOO_FAR to 32767. I do not want to delete these files permanently, so I will upload the files and the conversion script I made (I am not responsible for any harm it does on your machine). olli@niemi.com
