Hey, this is quite a minor change -- I'm fine if you don't take it.
However, we've found (in Power BI visual development) that mocking
requestAnimationFrame()allows us to "speed" through d3.transitions() in our unit tests. We've made this change locally for our d3's distribution, I thought it might be useful to share here.We use jasmine's clock to tick forward in time. We also use a "Scheduler" class to mock RAF to execute immediately, so we also make this change in the d3 source. Again, this is a "testability"-only change that may be useful to others mocking time in unit tests :)
