deepin20.9启动器修改大圆角为小圆角

获取源代码：

apt source dde-launcher

修改代码：

vim src/windowedframe.cpp，623行

case TopRight:
    path.moveTo(topLeft.x(), topLeft.y());
    path.lineTo(topRight.x() - m_radius, topRight.y());

    path.lineTo(bottomRight.x(), bottomRight.y());
    path.lineTo(bottomLeft.x(), bottomLeft.y());
    break;
