it's not clear to me why this change is relevant to the CL description. And why
should LTH have a different renderer setting from the display now?

[Alex Z., 2017/05/26 12:48:58]

You are right. I have reverted this changes.
This CL is part of the effort of separating RendererSettings from
LayerTreeSettings. The whole task is diced up into smaller chunks to
avoid large CLs. Sometimes the border of each CL gets blurred.

As for Display having a different renderer settings, LTH doesn't
consume the renderer settings. It passes it along when creating
Displays and ResourceProviders. We decided to leave some fields as
default instead of deleting them for now to have smaller CLs.
