昨天发错地方了，重新发一下，顺便增加一个功能，无操作两秒自动隐藏按钮
webview + floaty.rawWindow 写的简易浏览器，可以一边看电影一边干别的（比如写代码:joy: :joy: ）如果你的浏览器自带浮窗就用不着了
浏览器功能：
- 网址访问
- 前进
- 后退
- 刷新
- 停止
窗口功能：
- 拖动 （窗口边缘，有一部分看不见的区域）
- 手势缩放窗口大小
- 自动隐藏按钮
效果
（:thinking_face: 按钮还是有点扎眼了，可以写个功能隐藏一下。还有就是上面三个符号有点坑）
（输入网址时会把窗口暂时移到看不见的地方，毕竟悬浮比较碍事）
隐藏按钮效果如下
（缩放大小有限制可以自己改，初始大小也最好调一下）
代码
简述：浏览器的几个功能都是调用webview的几个方法，很容易就实现了，没有设置webChromeclient之类的东西（试了一下，直接崩了 :disappointed: ）。缩放大小通过给webview设置ScaleGuestureDetector，效果就勉强吧。（代码可能有点乱，格式化的‘副作用’）

最后：
复制粘贴，或者下载文件即可食用。要用auto.js4.0版本或者自己把rawWindow改成window好像也没什么问题。
