Description

[Jeff Muizelaar [:jrmuizel]]

Once we have separate documents we want to be able to have separate DirectComposition visuals for them so we can present each document separately

I think we might be able to just take a short cut and do bug 1550029 first for the mvp

"DirectComposition based document composite with Document splitting" is enabled with the following prefs

• gfx.webrender.split-render-roots: true
• gfx.webrender.split-render-roots-surfaces: true

Document splitting added Popover document. The patch does not render the Popover document yet. Size of the Popover document is same to window size. When we allocate a dc layer for the Popover document, memory usage increases a lot.
