strokeBorder(_:lineWidth:antialiased:)

Returns a view that is the result of filling the lineWidth-sized border (aka inner stroke) of self with content. This is equivalent to insetting self by lineWidth / 2 and stroking the resulting shape with lineWidth as the line-width.

@export(implementation) nonisolated func strokeBorder<S>(_ content: S = .foreground, lineWidth: CGFloat = 1, antialiased: Bool = true) -> StrokeBorderShapeView<Self, S, EmptyView> where S : ShapeStyle
