The only problem I can see with this is that (if I remember correctly) each GIF frame can have a different duration. This is easier to implement by setting up single add_timeouts as needed rather than repeat_timeouts, but probably run less efficiently. Also, I suppose the increment-and-wrap-to-0 could still figure out which frame to display based on the total time that has passed, so it should not really be an issue.
