+| `GUILayoutOption[]` | EmptyLayoutOptions | Empty GUILayoutOption array. You can use this instead of nothing to avoid allocations.  For example: <code>GUILayout.Label("Hello world!", IMGUIUtils.EmptyLayoutOptions);</code>  At that point you might also want to use GUIContent (created once and stored) instead of string. |
