Is the game running fullscreen?

It is possible to toggle fullscreen mode by changing this property:

	// Toggle fullscreen
	Screen.fullScreen = !Screen.fullScreen;

using UnityEngine;
using System.Collections;

public class Example : MonoBehaviour {
    void Example() {
        Screen.fullScreen = !Screen.fullScreen;
    }
}

import UnityEngine
import System.Collections

public class Example(MonoBehaviour):

	def Example() as void:
		Screen.fullScreen = (not Screen.fullScreen)

A fullscreen switch does not happen immediately; it will actually happen when the current frame is finished.
