I tried to introduce the least hacks possible. Nevertheless, I consider the
entire script is a hack.
I haven't stress tested it, so I don't know where are the performance
bottlenecks. I guess it depends on the JS engines.
The main difficulty is implementing additivity. The script need a major
rewrite for that (i.e it doesn't strictly follow the model SMIL defines :
aka sandwich model).
Another bug is that animations' starts are not strictly calculated, but
relies on events. So they may become out of sync, if they are repeated many
times.
Apart from that, everything was pretty straightforward, if I remember well.


(There's also that timesheet implementation :
