We must revisit CoreImage filters added in Xcode9, we added stubs for them here https://github.com/xamarin/xamarin-macios/pull/2191/commits/dfd52f5f694121dbaf977b2f15b6eb2f677d3b24
More filters in beta 2: https://github.com/xamarin/xamarin-macios/pull/2241/commits/71b4566436ff6e06ffb10c3e21cf1051b5595d6a
Also this API must be enabled once we bind CoreImage
More filters in beta 5: https://github.com/xamarin/xamarin-macios/pull/2447/commits/450d48b9f3486d8a8d030e60823425c06c35c11f
Maybe we should comment out the filters we stubbed out until we can fix/implement them?
@Vincent please put the stubs under `#if false // bug 57350` so the release is not misguiding the customers about the filters. Thanks!
@Sebastien filters skipped in https://github.com/xamarin/xamarin-macios/pull/2698
