Pretty interesting, I'd expect it to loose a bit of precision due to
rounding errors - but not that much.  Is it time to start thinking
about working at a higher precision internally and only attempting to
round down when it's absolutely necessary - i.e. when encoding to the
output file.

For those of you without JavaScript, I've extricated the images - you
can see them at:

Basically; single-pass-*.jpg are the versions with just a single pass
of the filter applied and the ones called quad-pass-*.jpg are the ones
with the filter applied four times.

Have fun,
