<description>
Returns the current refresh rate of the specified screen. If [code]screen[/code] is [code]SCREEN_OF_MAIN_WINDOW[/code] (the default value), a screen with the main window will be used.
[b]Note:[/b] Returns [code]60.0[/code] if the DisplayServer fails to find the refresh rate for the specified screen. On HTML5, [method screen_get_refresh_rate] will always return [code]60.0[/code] as there is no way to retrieve the refresh rate on that platform.
