Thanks for the explanation @fredrik. It wasn't clear to me how multi-planes buffers are handled (also that it's the same notion as for hw-planes is annoying!).

Until we support multi-plane buffers shouldn't we then filter out all multi-plane formats in the supportedFormats call such that the client does not even try to use these instead of just failing with null here?
