Replaced setTimeout with requestAnimationFrame

[pwolaq]

So I finally found some spare time and went a step further and replaced setTimeout with requestAnimationFrame as previously suggested.

I have removed delay parameter for now, but it is possible to implement it to throttle updates - please tell me what do you think about it :)

This is awesome, thank you very much @pwolaq.

I'm happy to merge it but I was wondering how hard it is in you opinion to keep the delay prop (and avoid a breaking change).

[pwolaq]

I've implemented the delay prop, but also encountered some weird behaviour with tests - after I added a new test for delay prop some of the tests started to fail.

I will try to fix it tommorow.

[MicheleBertoli]

You are the best, @pwolaq.

It turns out that I had to call jest.clearAllTimers after each test in order to prevent this weird behaviour. It should be ok now.
