FrameInfo will now be per-window; that is, per-ViewRootImpl. Some of the information should remain “global” (it remain in Choreographer), while some information is going to become ViewRootImpl-specific. Before the information gets passed to the native layer, the ViewRootImpl-specific info will be stitched together with the general Choreographer info. This change is useful in order to correctly correlate frames with a specific input event. In the unlikely scenario of a user touching two windows of the same app simultaneously, this change will allow us to correctly measure the latency of both frames produced by the windows.
