10 *修复获取安全区尺寸的正确数据
11 *重构适配数据的计算逻辑
12 *重构全屏显示
13 *新增RawImg自适应等比缩放（合并脚本）
14 *重构后适配可根据具体上下左右安全区范围做显示

基本完成UGUI适配功能
*Screen.safeArea不支持Android8.0及以下的信息获取，如果需要单独添加设备适配配置
当然也可以跟我一下 忽略。。。
针对折叠屏的适配，暂时可以在Android层添加onConfigurationChanged监听
然后在Unity里面调用一下适配刷新即可
折叠屏的适配-这里同样可以
1 if (!lastCanvasSize.Equals(mParentCanvesRT.sizeDelta))
2 {
3 lastCanvasSize = mParentCanvesRT.sizeDelta;
4 invokeRefreshFrame = true;
5 }
