The Wayland server API has changed so that wl_shm_buffer is no longer a type of wl_buffer and it instead must be retrieved directly from the resource. cogl_wayland_texture_2d_new_from_buffer now takes a resource pointer instead of directly taking a wl_buffer and it will do different things depending on whether it can get a wl_shm_buffer out of the resource instead of trying to query the buffer type. Cogland has also been updated so that it tracks a resource for buffers of surfaces instead of directly tracking a wl_buffer. This are pointed to by a new CoglandBuffer struct which can be referenced by a CoglandBufferReference. The WL_BUFFER_RELEASE event will be posted when the last reference to the buffer is removed instead of directly whenever a new buffer is attached. This is similar to how Weston works. https://bugzilla.gnome.org/show_bug.cgi?id=702999 Reviewed-by: Robert Bragg <robert@linux.intel.com> (cherry picked from commit 9b35e1651ad0e46ed489893b60563e2c25457701) Conflicts: examples/cogland.c
