While YES, scrollViewDidScroll: no longer reconstructs drawOrigin from the clip view geometry.
Declaration

@property (nonatomic) BOOL viewportAnimationDrivesDrawOrigin;Declaration
viewportAnimationDrivesDrawOrigin() -> bool
setViewportAnimationDrivesDrawOrigin_(viewportAnimationDrivesDrawOrigin: bool)Discussion
The viewport animation drives it directly via setViewportAnimationDrawOrigin: instead. Set by GSFrameView for the duration of a viewport animation, because the clip view scroll can lag under load.
