Animation slowdown detector (does not handle pausing)

u/pavel

I've noticed animations being slower on my iphone. This dweet shows a ratio of 1 on my macbook but 0.558 on my phone!
u/pavel

This is a Safari issue; runs at .558 on phone and mac. Mac Chrome runs at 1.
u/prplz

Same result on my iPhone/safari too
