当 exSpriteFont.text 没有文字的时候，会发生 GetAABoundingRect 数组越界的问题 #12

Call Stack 如下：

IndexOutOfRangeException: Array index is out of range.
exGeometryUtility.GetAABoundingRect (UnityEngine.Vector3[] _vertices) (at Assets/ex2D/Core/Utilities/exGeometryUtility.cs:86)
exSpriteBase.GetAABoundingRect () (at Assets/ex2D/Core/Components/exSpriteBase.cs:472)
exSceneEditor.MapBoundingRect (Rect _rect, .exSpriteBase _node) (at Assets/ex2D/Editor/exSceneEditor.cs:1173)

exSceneEditor.Layout_SceneViewField (Int32 _width, Int32 _height) (at Assets/ex2D/Editor/exSceneEditor.cs:533)

应该在 GetAABoundingRect 里加上保护。
