Box Decoration for RectangleComponent

### Problem to solve

The ability to style a rectangular position component with radius for border, border radius, border color, background color, border shadow (blur, color and offset), etc. and maybe hover over color.

I think this would be very useful for a lot of people, although this feature is definitely not urgent as the desired result can already be achieved (albeit with a bit of redundant code).

### Proposal

Maybe a mixin on PositionComponent could make sense ?
