This will check whether the current backing buffer is compatible with the primary plane of the passed CoglOnscreen. Since this will extend the time before a buffer is released, the MetaWaylandBufferRef is swapped and orphaned if a new buffer is committed before the previous one was released. It'll eventually be released, usually by the next page flip callback. Currently implemented for EGLImage and DMA-BUF buffer types. https://gitlab.gnome.org/GNOME/mutter/merge_requests/798
