Shortcut for an empty GUIStyle.

This style contains no decoration and just renders everything in the default font.

	function OnGUI () {
		// Make a button with no decoration
		GUI.Button(Rect(0,0,250,100), "I'm very bare", GUIStyle.none);
	}

using UnityEngine;
using System.Collections;

public class Example : MonoBehaviour {
    void OnGUI() {
        GUI.Button(new Rect(0, 0, 250, 100), "I'm very bare", GUIStyle.none);
    }
}

import System.Collections

public class Example(MonoBehaviour):

	def OnGUI() as void:
		GUI.Button(Rect(0, 0, 250, 100), 'I\'m very bare', GUIStyle.none)
