The total amount of time that we could reasonably be checkerboarding.
This is the union of two possibly-intersecting sets of time periods:
The first set is that in which checkerboarding was actually happening,
since by definition it could potentially be 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.

opened a tab since they were updated to a version where webrender should
be enabled on their device. This can be used to verify that theory.
