		The first set is that in which checkerboarding was actually happening,

		The second set is that in which the APZC is actively transforming content
		in the compositor, since it could potentially transform it so as to display
		checkerboarding to the user. Combined with other information, this allows us
		to meaningfully say how frequently users actually enncounters checkerboarding.
