1351495 - Figure out how to integrate DisplayItemLayer and WR blob renderer

Status: RESOLVED WONTFIX

(Core :: Graphics: WebRender, enhancement)

Description

For items such as  nsDisplaySVGGeometry and ThemedBackground, we probably can't convert these directly to WR display items. nsDisplaySVG is too complicated and ThemedBackground usually has to call into native APIs to draw things. This will probably use the blob renderer. Figure out how to integrate those items + DisplayItemLayer or if it should bypass them completely.

I suspect we can have the blob renderer handle painted layers and then just let nsDisplaySVGGeometry and ThemedBackground be grouped into painted layers for now.
