- The associated CoglAttribute's are now stored in GPtrArray as suggested by carlosg in https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3193?commit_id=19b619073b3c7d311c64e0a997558f943b38c94a#note_1849281 - cogl_primitive_set_attributes was dropped for "simplicity" especially that nothing uses it. - As this is the last remaining CoglObject subclass, the commit also drops all the CoglObject related macros/types Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3193>
