QML弹出窗口组件，灯箱效果、动画效果，可拖拽
核心思路：一个mask层，一个最顶层，都用rectangle，禁止事件穿透
使用
Popup {
id: popup
200; height: 300
x: 200; y:100
z: 101
opacity: 0.8
visible: false;
radius: 5
...
}
popup.showMask = chk.checked;
popup.animationType = 'size';
popup.show();
注意
使用位移动画不能用anchors定位方式

万能的qml，编起UI好开心。
再也不用管div、css、box原型、相对定位、绝对定位、浏览器适配、低性能的canvas...坑爹的html+js，无穷尽的js框架，这么多年了，怎么都摞不顺，永远扶不直的阿斗。
自从用了qml，整个人心情都舒畅了，腰也直了，背也不弯了，考试天天考100分
