There is now a new mechanism for dealing with the background image
collection, including a new update script. Please read the newly-
rewritten bg/README.backgrounds for details.
Also, I'm trying to flesh out the Contributors list in that file, but
my memory isn't cooperating. So if you contributed one of the
backgrounds, or know someone who did, please let me know.

Added new shade/tint routines, including some done in MMX assembly, by
Willem Monsuwe <willem@stack.nl>. Thanks Willem! These should prove
to be faster than the old stuff, probably by quite a bit.
