	/// Proposes a percentage of its received proposed size to `self`.
	///
	/// This modifier multiplies the proposed size it receives from its parent
	/// with the given factors for width and height.
	///
	/// If the parent proposes `nil` or `.infinity` to us in any dimension,
	/// we’ll forward these values to our child view unchanged.

	/// This helps achieving what `UIView.ContentMode.scaleAspectFit` and `.scaleAspectFill` do in UIImageView.contentMode
	///
	/// The difference between Image.containerAspectRatio (this) and SwiftUIs View.aspectRatio is that the first applies the
	/// aspect ratio to the view that contains the image, rather than to the image itself.
	///
	/// So in the following example:
	/// - The first image will scale to a square but the contentMode does not do anything to prevent stretching and wether you use .fit or .fill does not matter.
	/// - The second image will resize to fit inside a square while maintaining its aspect ratio, similar to how a UIImageView with contentMode set to scaleAspectFit behaves.
	/// - The third image will resize to fill inside a square while maintaining its aspect ratio similar to how a UIImageView with contentMode set to scaleAspectFill behaves.

	/// While iterating, all emitted elements are retained within a `Set` to ensure uniqueness of each element emitted.
