MapXtreme 2008水印處理方法

目前MapXtreme 2008的破解無法消除水印。既然無法去除，只好選擇土點的方法，把水印遮蓋住就行了。
         本人共使用了3個DIV.
         第一步：放置DIV
         第一個DIV用來存放map控件，第二個DIV放在MAP上用於覆蓋MAP,與map同大小。在overlay再嵌個div，高度與水印高度相同，遮住水印。OK，水印沒了。
         第二步更改代碼：        
          在interaction.js中加入代碼，使拖動時overlay與地圖圖片一同移動，這樣就實現了拖動時也不會出現水印。

修改DragInteraction.prototype.OnMove、DragInteraction.prototype.OnUp即可。
