1432888 - Tighten up the integration of nsDisplayList and the WebRenderDisplay list

Status: RESOLVED WONTFIX

(Core :: Graphics: WebRender, enhancement, P2)

Description

[Jeff Muizelaar [:jrmuizel]]

There are a number of things that we can do here:
1. Compute all the frame information that we'll need and store it in the nsDisplayItem so that we don't need to visit the frame.
2. Only send the newly built display items from retained display lists and do the merging on the WebRender side
3. Avoid sending all of the information all of the time. i.e. Use ids for glyph runs that are maintained across paints.

Any kind of incremental updating will probably need some kind of id stability which we don't really have a great way of maintaining currently.
