For formats which we don't have fast-path implementation, compositor will convert it to common unpack formats (AYUV, ARGB, AYUV64 and ARGB64) then blending will happen using the intermediate formats. Finally blended image will be converted back to the selected output format if required. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1486>
