Box shadow helper is a helper which draws box shadows, similar to CSS box-shadow property. The only thing it's missing is the spread property.
Demo
```lang=cpp
Breeze::BoxShadowHelper::boxShadow(
&painter,
QRect(300, 200, 200, 200),
QPoint(0, 50),
96,
QColor(0, 0, 0));
```
// the size of the canvas is QSize(800, 600) //
