More legible segments

[joshwcomeau]

This component mimics a "seven-segment display": https://en.wikipedia.org/wiki/Seven-segment_display

I chose a simple implementation at first: each segment is exactly the same shape and size, and I'm just rotating them around.

Unfortunately, this means the end result isn't as legible as it could be, especially with thicker segments. Compare this component to another seven-segment display using trapezoids around the edge pieces:

I think it would be good to move towards that alternative version, as the numbers are much easier to read.
