The following histograms will be expiring on 2017-04-17, and should be removed from the codebase, or have their expiry versions updated:

* CHECKERBOARD_DURATION expires in version 55.0a1 (watched by kgupta@mozilla.com) - Duration of a checkerboard event in milliseconds
* CHECKERBOARD_PEAK expires in version 55.0a1 (watched by kgupta@mozilla.com) - Peak number of CSS pixels checkerboarded during a checkerboard event (the high value is the size of a 4k display with max APZ zooming)
* CHECKERBOARD_POTENTIAL_DURATION expires in version 55.0a1 (watched by kgupta@mozilla.com) - Duration of a chunk of time (in ms) that could reasonably have had checkerboarding
* CHECKERBOARD_SEVERITY expires in version 55.0a1 (watched by kgupta@mozilla.com) - Opaque measure of the severity of a checkerboard event
* CONTENT_RESPONSE_DURATION expires in version 55.0a1 (watched by kgupta@mozilla.com) - Main thread response times for APZ notifications about input events (ms)


We should probably keep the first four listed here until at least Firefox 58 or so - enough time to let QuantumRender land and stabilize. The last one we could probably let expire / remove, since we wanted it for tuning the content response timeout. However I think it might be valuable to keep that around until 58 as well, so see if the QuantumRender changes have any impact on it. The QR changes will affect the painting pipeline somewhat and so it might affect how long the main thread takes to get back to the compositor with respect to input event handling.
