Is it beneficial to add the @mainactor annotations? I expect these functions are currently used on the main thread but at their core it's only math calculations which aren't thread specific

@skorulis-ap this needs to be MainActor for UIView to have a valid conformance on L27, but that means all the calculations that use LayoutDirectionProviding also need to be marked MainActor

@skorulis-ap same story here, it's just math but using scale here requires MainActor:
extension UIScreen: ScaleFactorProviding {
public var pixelsPerPoint: CGFloat {
return scale
}
}
it unfortunately is viral from there and all math that uses pixelsPerPoint then requires MainActor
