Custom Visual Bell

Allowing User Customization of the Visual Bell

I came across this thread in which custom bell sounds were added, and realized that it could also be useful to customize the visual bell as well. I think the most straightforward customizations would be:

1. Allow changing the color, intensity, and duration of the default behavior (for instance, a normally black terminal flashing red briefly instead of grey) and/or
2. Adding, or overriding any background image with one indicating failure (see below)

AKA the jumpscare bell.

seriously though this would be very useful to anyone who doesn't benefit from an audible bell.

I'm not totally opposed to this, for sure. Seems like it's got great potential. But we'd need to figure out how the settings should be expressed.

Initial guess:

"visualBell": {
  "duration": 200,
  "color": "#ff0000",
  "intensity": 80,
  "backgroundImage": "walt.gif",
  "backgroundImageOpacity": 25
}

And those would only apply if you've got visual bells enabled. Idk. Just a thought.

If someone wants to come along and help define this, I'd be all ears.
