"""生成 Windows .ico 和安卓图标，用 _build/icon_source.png 作为源图。
|
|
|
|
原来是自己画一个蓝色圆角方块（lanremote.ui.make_icon_image）。
|
|
现在改成用作者给的那张图。
|
|
|
|
产物：
|
|
windows/app.ico 给 PyInstaller
|
|
android/res/drawable-{m,h,xh,xxh,xxx}dpi/ic_launcher.png
|
|
（并删掉旧的矢量 res/drawable/ic_launcher.xml，不然同名资源会冲突）
|
|
|
|
源图是方形线稿，安卓启动图标习惯留点边距，所以缩到 88% 再居中放。
