Add option to disable "bg_vignette" in game.

[. . .]

I noticed in config.lua there is

local defaults =
{
	hide_vignette = false,
	force_netbookmode = false,
}

local platform_overrides =
{
	
	NACL=
	{
		force_netbookmode = true,
	},
	ANDROID =
	{
		hide_vignette = true,
		force_netbookmode = true,
	},
	IOS =
	{
		hide_vignette = true,
		force_netbookmode = true,
	},
}

which seems there's an option on mobile to disable the "bg_vignette" which's always active on other platforms, it would be really nice if this option could be added to PC too I'm sure it wouldn't be difficult and it would make some players who want to see the colors of the game better or not have vignette happy

The vignette is the border shade effect, and colourcubes effect the saturation curves.

If you're wanting the vignette off, or other overlays, then I do have a mod on the workshop to do just that:

Configurable.

As for colourcubes there's a few mods that also fix that, or disabling the PostProcessor does it too.
