Viewports do not inherit project default rendering settings

Issue description:
Viewports do not inherit project default settings, requiring the user to manually set MSAA, Shadow Atlas, etc

Minimal reproduction project:
GLES3.zip

You need to set the shadow atlas size in the shadow atlas group of the Viewport

Odd, I recall messing with the value and it not changing anything, but it appears to work now. I suppose the better question is why does viewport not automatically use the defaults set in the project settings

[Calinou]

If viewports are made to inherit project settings by default, how could specific settings be overridden?

[triverske]

Maybe a specific "override" mode or something of that nature? Or maybe when you create the node it automatically could have the default values in there.

[Calinou]

@triverske The issue is that properties are only saved to scene files if they differ from the default (as of Godot 3.1). Therefore, if the project settings are identical to the Viewport's default settings, the property wouldn't be saved to the scene file, which would make the behavior inconsistent with project settings that don't match the Viewport's defaults.

[triverske]

Perhaps a checkbox then that just says "inherit from project settings" then, that at least will let people know that by default they won't get applied to a newly created viewport

Just got bit by this, thought something was broken with inheritance.

Hopefully this becomes a priority soon, or at least documented somewhere in a faq on pixel art games.
