DEF_GANESH_TEST()

DEF_GANESH_TEST	(	OpChainTest	,
		reporter	,
		CtsEnforcement::kApiLevel_T
	)

Tests adding kNumOps to an op list with all possible allowed chaining configurations. Tests adding the ops in all possible orders and verifies that the chained executions don't violate painter's order.
