We should do something about these ancient ways of animating things. At the very least, displaying a huge red flashing banner PLEASE DON'T USE SETINTERVAL FOR ANIMATION should do the trick :)

Shelving a very wip patch.

Do we have any intention of supporting this, especially once we make clear that it's recording a rAF frame (bug 985488)? Can also provide an even more explicit explanation of "Don't use setTimeout/setInterval *link*"
I'd like us to support it. There's a lot of demos on the internet that *STILL* use setInterval. However, we should make it absolutely clear that it's a Bad Thing and the developers should feel Bad.
Gonna take a look at this.

Summary: Support setInterval and setTimeout as animation generators in the Canvas Debugger → Support setTimeout as animation generators in the Canvas Debugger
As per discussion in IRC, changing this to only support setTimeout at this time, as it'll be more common than setInterval due to the popular rAF shimthat uses it, and similarities it shares to rAF in function signature. This'll need to be rebased hard with the other canvas debugger patches. A few things are built out, as if the rAF/setTimeout paths are different, but those can be merged all into one ANIMATION_GENERATOR array, as their implementations are identical, just a matter of taste splitting them up in the actor. https://treeherder.mozilla.org/#/jobs?repo=try&revision=4deecf570828  http://www.paulirish.com/2011/requestanimationframe-for-smart-animating/
