Tips screen aspect ratio

Our patch changes the game from 4:3 to 16:9 pretty much everywhere except for the tips screen. We can replace the background in the assets with a 16:9 image but even when we did that, it did not stretch to the edges in the game.

查找提示屏幕的渲染代码，可能在 UI 或屏幕管理类中。检查背景图像的加载和缩放方式；该问题提到了资源和拉伸。通过将背景资源替换为 16:9 图像进行测试，查看缩放逻辑是否需要调整。通过运行游戏并检查提示屏幕是否填满屏幕来验证修复。
