While I do like your thought process there, keep this is mind:
"If Tauwasser documents the decompression routine, maybe someone else will create a tool to recompress graphics for him "
He posted the documentation on the wiki in German on March 25th, 2006. He did a rough English translation on June 12th, 2010. It's September 7th, 2011, and only now are we getting close to a compression tool.
Because I already know what I'm doing (for the most part), I feel obligated, I feel it's my duty to finish this out.
...hopefully before Christmas.
