SwiftUI component that provides a flat background color for Preview based on the environment setting.

This allows it to be used to provide background shadings appropriate to the mode, regardless of device:

```swift

#if DEBUG

struct PreviewBackground_Previews: PreviewProvider {

    static var previews: some View {

        Group {

            ForEach(ColorScheme.allCases, id: \.self) { colorScheme in

                PreviewBackground(content: {

                    Text("hi")

                })

                    .environment(\.colorScheme, colorScheme)

                    .frame(width: 100, height: 100, alignment: .center)

                    .previewDisplayName("\(colorScheme)")

            }

        }

    }

}

#endif

```
