Reland: Report total event latency metrics to UI compositor Whenever a presented frame in the browser compositor has associated events, total latency for those events are reported back to UI compositor. The UI compositor can decided if/how to report those metrics. This was originally landed as r1002811, but got reverted due to making a bunch of interactive UI tests flaky. The reason for the flake was a DCHECK that expected the presentation timestamp be strictly greater than the event timestamp. However, it is conceivable that, at least in tests, the two timestamps are equal. So, this reland changes the DCHECK to expect the presentation timestamp is greater than or equal to the event timestamp.

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.
The project's web site is https://www.chromium.org.
To check out the source code locally, don't use git clone
! Instead, follow the instructions on how to get the code.
Documentation in the source is rooted in docs/README.md.
Learn how to Get Around the Chromium Source Code Directory Structure .
For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
