A more aggressive purge plays nicely with another thing I would love to see:

We got tons of buy-in for "pausing" animations which aren't currently visible.
IE when we scroll an image back into view, we resume where we left off rather than try to catch up to where it would have been.

We can stretch this idea a tad further and say if the image wasn't used in 30s / 1m / whatever then we can just purge it all and start over from the beginning of the animation.

I think that is the correct trade-off to make. We always reduce memory usage. And we only pay extra CPU as needed, *IF* needed.


Khushal landed some great code to tick animations in CC rather than Blink. Once the dust settles from that, we can add the "pausing" of animations followed by starting over when an animation is purged.

Assigning to ericrk@. Should this be P1?

Dropping priority to P2 and marking available. This would be nice to have, but I probably won't have time to work on it in the immediate future.
