> This patch is proposed to introduce new compositing layers and leverage GPU acceleration for those typical cases as I mentioned above.
> Could you please kindly help to provide any clues for the implementation of existing accelerated animating 2D transforms since I am not familiar with this?

See the existing code that toggles compositing when a transform starts/stops animating. Simon is asking whether that's what your patch is trying to do. If so, it's already done. If it's trying to turn on compositing everywhere for 2d transforms, then we don't really want to do that for the reasons we've already mentioned. Is this patch trying to do something else?
