Styling Vision Camera widget overlays?

Greetings.

I think it would be great if we had more control over the look/style of the Vision Camera overlays. E.g. rectangle stroke (width, color and opacity), fill (color and opacity) around the rectangle, maybe even fill (color and opacity) inside the rectangle?

One of my customer captures regions of a camera image stream for further processing. They would like to control how the snapshot overlay renders above the Vision Camera widget. Currently, the overlay always render as a red stroked empty rectangle surrounded by a slightly dark gray area. They would like to get rid of the red stroke and work using only with the gray translucent area around it.
