sued after the barrier
                        will reflect data written by shaders prior to the barrier.
                        Additionally, image stores and atomics issued after the barrier will
                        not execute until all memory accesses (e.g., loads, stores, texture
                        fetches, vertex fetches) initiated prior to the barrier complete.
