 				[b]Note:[/b] On Linux (Wayland), the returned value is accurate only when [param screen] is [constant SCREEN_OF_MAIN_WINDOW]. Due to API limitations, passing a direct index will return a rounded-up integer, if the screen has a fractional scale (e.g. [code]1.25[/code] would get rounded up to [code]2.0[/code]).
