1486647 - Add a metric for paint processing time.

Status: RESOLVED WONTFIX

(Core :: Graphics: WebRender, enhancement, P3)

Description

[Jeff Muizelaar [:jrmuizel]]

This should track how much time we actually spend doing work during paint. Because this doesn't include waiting time it should be more understandable and comparable than CONTENT_FRAME_TIME even if it is not as reflective of real user experience.

This isn't important to track.

Comment 3

[Glenn Watson [:gw]]

I don't think this is relevant any more.
