I think we should also suspend animations for background windows.

this patch is bitrotted to hell as a result of the new imgcontainer architecture.

Suspending for background windows should be pretty trivial once two other things land:
1) bug 512260
2) animation cleanup

After that, we should be be able to start animation when we lock the images and pause animation when we unlock them.

and by background windows I mean inactive tabs. Probably could be extended to windows if the window managing code learns how to use the api in bug 343515.

Is this feature still wanted? This patch is heavily rotted.

We should implement this by suspending/throttling the refresh driver on system idle. No further work is required now that bug 666446 is implemented.
