[REBOL] Re: auto-update engine

That's very interesting.
You can use xor directly on images too.
I tried today to make a movie system
with a key frame and diffs for the rest,
calculated with xor, and it works, but I
concluded that using rebol's built in 'compress
is not as good as the dedicated compression
used by other programs (such as RADTools
Bink Converter, which is what I used to create
compressed png's).
That doesn't mean the fight is over yet.
I could save my diff images, then resave them
using an external tool like Bink.
Rebol's png's seem quite large, so I assume
they are saved simply with no compression.
