截图优化 (#1480)
* BitBlt 优化 * BitBlt恢复Top-down * 渲染时翻转图像 * CaptureSession引用计数 * 恢复成无拷贝Mat * 合法性检查 * 优化截图预览窗口 * 保存截图文件必要时需要克隆一份Mat * BitBlt内存池 * 返回拷贝就不用对Session做引用计数了 * 移除CaptureImageRes * 优化DirectX * 更好地处理padding * BitBlt去掉padding 1920*1080的游戏窗口是4字节对齐的,因此不会有性能影响。这里主要用于测试。 * 修复修改窗口大小 * 合并CreateStagingTexture * 修复设备丢失崩溃 * WGC截图支持HDR * fix typo * CodeQA * 去掉1px窗口边框 * DirectX截图去掉A通道 * HDR转换使用GPU加速 --------- Co-authored-by: 辉鸭蛋 <huiyadanli@gmail.com>
