This property sets the amount that the view is scaled in X & Y around the pivot point, as a proportion of the view's unscaled width. A value of 1 means that no scaling is applied. Actually UI.flipVertically flipVertically & UI.flipHorizontally flipHorizontally functions are assignes -1 to X & Y to mirror the view. So while using scale, need to consider these functions.

Gets as any arguments as it needs
Rest ...args: any[]Adds the listener function to the beginning of the listeners array for the event named eventName. No checks are made to see if the listener has already been added. Multiple calls passing the same combination of eventName and listener will result in the listener being added, and called, multiple times.
