This new API allows compositors to display buffers without needing to perform rendering operations. This API can be implemented on Wayland using subsurfaces and on DRM using KMS planes. The goal is to make use of this API in a future scene-graph API. References: https://github.com/swaywm/wlroots/issues/1826
