WPF WindowChrome 自定義標題欄時窗體陰影效果設置

即將GlassFrameThickness值設置為"0,0,0,1"，此時即可獲得陰影效果，此陰影效果為系統默認（測試系統是Win10）

參考鏈接：https://stackoverflow.com/questions/5897495/shell-integration-library-windowchrome-with-drop-shadow

在MSDN沒查到相關說明

備注：在測試中發現將ResizeMode直接寫在Window標簽屬性上而不是以Style.Setter的方式賦值，當值為NoResize時，窗體會無陰影效果；當Win.SizeToContent = SizeToContent.WidthAndHeight，窗體會有黑色邊塊
