Summary:
Since api level 34 there is a way to snapshot any view, prior to this you needed a window which you can only get from an activity, or a surface which required hacks. The hacks are in place for older verisons of android but ive added modern pixel copy snapshotter for future proofing in case google decide to make any of the previously used hack not work in future version of android
Since there was a bunch of common code in each snap shot impl this has been pull into a utility function
