Example: LayoutTests/animations/animation-direction-reverse-timing-functions.html LayoutTests/animations/animation-direction-reverse-timing-functions-hardware.html The latter should be completely hardware-accelerated.

Running the tests on recent AAS it seems that this is working properly.

This patch will be correct in a future version of CoreGraphics.

CoreGraphics is fine. The Windows port was simply missing logic to invert the control points used in the timing function (see toCAMediaTimingFunction in PlatformCAAnimationMac.mm for details).

BTW - why not return CubicBezierTimingFunction::create(new points); ?
