Controls the ordering of operations on atomic counters issued by a single shader invocation.
memoryBarrierAtomicCounter waits on the completion of all accesses resulting from the use of atomic counters and then returns with no other effect. When this function returns, the results of any modifications to the value of atomic counters will be visible to any access to the same counter from other shader invocations. In particular, any modifications made in one shader stage are guaranteed to be visible to accesses performed by shader invocations in subsequent stages when those invocations were triggered by the execution of the original shader invocation (e.g., fragment shader invocations for a primitive resulting from a particular geometry shader invocation).
