This CL adds two histograms to help understand the percentage of frames that can be swapped immediately and frames that need to wait. GPU.Presentation.FrameHandlesAnimationOrInteraction GPU.Presentation.NonAnimatdOrInteractiveFrameWithPendingFrame When VSyncAlignedPresent and kPresentationDelayForInteractiveFrames are enabled, frames not handling interaction and animation can be swapped immediately. However, they must wait in the queue for VSync when there is a pending frame(s).
