Animated Gifs and http

That's with delta-frame animations. Two ways to fix this:

(1) image productions: generate full frames for each delta

(2) drawing: accumulative redrawing of delta frames (from the last
non-delta)

I currently tend towards (2), since it's somewhat
counter-productive to use deltas to get small image files, just to blow them up
subsequently during image production.

There's another issue I'm not completely sure about - animations with 0-delay
time. It seems netscape handles this as "one shot" animations (i.e. doesn't
continuously loop through the frames. Does anybody know about this?
