The idea is that anything in the transient storage can be regenerated. So if it is zeroed out, it will just rebuild itself, since none of it is "state".
For example, we keep the bitmaps there, but the bitmaps can just be reloaded from the asset file at any time. There is no "state" associated with the bitmaps. So if we lost the transient memory, it wouldn't matter, because it can be completely reinitialized again from the permanent game state without losing anything.
Does that make sense?
