/// struct Star: View {
/// var color = Color.yellow
///
/// var body: some View {
/// Image(systemName: "star.fill")
/// .foregroundStyle(color)

///
/// By setting different `alignment` values for each modifier, you make the

///
/// ![A screenshot of a rounded rectangle with a star in each corner. The
/// star in the upper-left is red; the start in the upper-right is yellow;
/// the star in the lower-left is green; the star the lower-right is

/// If you specify more than one view in the `content` closure, the modifier

/// .frame(width: 200, height: 200)
/// .overlay {
/// Circle()
/// .frame(width: 100, height: 100)

/// }
///
/// Both the overlay modifier and the implicit ``ZStack`` composed from the

/// ``Alignment/center`` alignment. The star appears centered on the circle,
/// and both appear as a composite view centered in front of the square:
///
/// ![A screenshot of a star centered on a circle, which is
/// centered on a square.](View-overlay-3)
///
/// If you specify an alignment for the overlay, it applies to the implicit

/// Color.blue
/// .frame(width: 200, height: 200)

/// centered on the circle:
///
/// ![A screenshot of a star centered on a circle, which is on a square.
/// The circle's bottom edge is aligned with the square's bottom
/// edge.](View-overlay-3a)
///
/// To control the placement of individual items inside the `content`
/// closure, either use a different overlay modifier for each item, as the

/// Color.blue
/// .frame(width: 200, height: 200)
/// .overlay(alignment: .bottom) {
/// ZStack(alignment: .bottom) {
/// Circle()
/// .frame(width: 100, height: 100)

/// }

/// circle's, while the overlay aligns the composite view with the square:
///
/// ![A screenshot of a star, a circle, and a square with all their
/// bottom edges aligned.](View-overlay-4)
///
/// You can achieve layering without an overlay modifier by putting both the
/// modified view and the overlay content into a ``ZStack``. This can
/// produce a simpler view hierarchy, but changes the layout priority that
/// SwiftUI applies to the views. Use the overlay modifier when you want the

///
/// If you want to specify a ``ShapeStyle`` like a ``Color`` or a

///
/// - Parameters:

/// is ``Alignment/center``.
/// - content: A ``ViewBuilder`` that you use to declare the views to
