//--------------------------------------------------
//  Desc: MS3D model Loader
//  Date: 2007.3.6 /update
//  Author: artsylee
//
//  Copyright (C) 2007 artsylee
//
//  Info: only support one texture & one material(2007_3_6)
//        Support Mulit-Texture, Mulit-Material, Mulit-Mesh(2007_3_8)
//		  改变纹理坐标转换以支持WOW模型导出(2007_3_8)
//		  只解释静态模型, 动画暂时不解释.
//  问题: 全屏切换时纹理消失.(估计是设备丢失时灯光问题)
