I am taking this one over.
I have analyzed the problem and found a solution that is not too hard to
implement.
The straightforward way to handle the rewinding of single effects seems to be
to, well, rewind the last effect (sequence) that was triggered by user input.
This turns out, as mentioned above, to be quite hard to implement with the
current architecture of the slide show.
A simpler but not quite so elegant way is to rewind the current slide and play
back all main-sequence effects except the last one. There are two drawbacks to
this approach:
1. When a main sequence effect is undone then all effects that do not belong to
the main sequence are undone as well. This includes for example effects
triggered by clicking on some shape. This behavior is unfortunate but I see no
way around it.
2. Redisplaying the current slide and then replaying the effects is probably
somewhat slower than just undoing the last effect.
