+
+        The RequestAnimationFrame spec has renamed cancelRequestAnimationFrame to cancelAnimationFrame in response to
+        feedback from Mozilla and Microsoft that the old name was too long and didn't parallel setTimeout/clearTimeout
+        and setInterval/clearInterval very well. This updates our IDL to match, while preserving the old name as an
+        alias to be compatible with current content.

+        Convert the time parameter from double to DOMTimeStamp using convertSecondsToDOMTimeStamp rather than relying on
+        implicit double->long conversion, which ignores the units of the value.

+
+        Changed requestAnimationFrame to use a Timer in ScriptedAnimationController
+        on Mac, rather than runLoopObservers. The Timer is throttled to fire no
+        faster than every 15ms. It is behind a WTF_USE_REQUEST_ANIMATION_FRAME_TIMER
+        flag and can be used by any implementation, but currently it is only enabled
+        by PLATFORM(MAC).
