First Paint Timing API

API to enable developers to measure time for First Paint (FP) & First Contentful Paint (FCP) -- the first key moments in loading that they care about. These moments are added as 'paint' entries in the Performance Timing API.


`performance.getEntriesByType('paint').forEach(entry => console.log(, entry.startTime))`
