- bump wayland version to 0.95.0 which will lead to stable 1.0 release - avoid memcopy and use propose_allocation for GstBufferPool allocation - using WaylandBufferPool - shm: Allocate shm buffers through new wl_shm_pool interface (the shm buffer allocation is a two step process now: first allocate a wl_shm_pool, then allocate a buffer from the pool) https://bugzilla.gnome.org/show_bug.cgi?id=681453
