Proposal: First Screen Snapshot

[xiaochengh]

Introduction

When loading a page, the user typically sees a blank screen before anything is displayed (aka first paint). This doc proposes a mechanism that caches the rendering of a developer-chosen section of the page, and displays it on subsequent loads of the same page as the first screen, so that the user no longer seens a blank screen at all.

The snapshot can be used to create a static splash screen (which is currently only available to PWA and hybrid apps with a WebView).

This is a very rough draft to gather some thoughts and see if this is something worth pursuing. Any comments are appreciated!
