ScalingDot using screen width.

[Garrick3491]

Hello, I have a screen in my react native app that is using scaling dots within a box, however the scaling dots is using screen width so the dots are updating at the wrong points.

I can fix this locally by adding containerWidth as an optional prop. This defaults to width if not passed.

Is this something that we can add?
