1244901 - Update potential checkerboarding duration probe to be entirely compositor-thread

Status: RESOLVED FIXED

(Core :: Panning and Zooming, defect)

Description

[Kartikaya Gupta (email:[e-mail]) (away until Feb-2020)]

The CHECKERBOARD_POTENTIAL_DURATION probe is computed by the PotentialCheckerboardDurationTracker class, which records checkerboard duration from the compositor thread and transform duration from the controller thread. For consistency and thread-safety, we should move the transform duration recording to the compositor thread as well. Conceptually this makes sense because checkerboard duration is recorded as time on the compositor thread, so the potential duration should also be time on the compositor thread.
