Summary:
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 but we don't need it pretty much.
Demo
Let's draw a box shadow for the rect QRect(300, 200, 200, 200) with the following params:
* blur radius: 96
* vertical offset: 50
* color: black
```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) //
{F5754369, layout=center, size=full}
