Any idea how to find "where" this is set or happens? If I can track it
down, I can compare to Pharo (which doesn't seem to have the issue I'm
describing) and see how they deal with it.
For anyone else interested in the problem / example I posted, I can supply
a changeset that really breaks out the LZW/GIF compression and
decompression stuff so that it's somewhat easier to step through. This is
part of the work I did refactoring the current implementation, which is
hard to follow.
